Van Heurck -- Synopsis des Diatomées de Belgique -- Index

Notes

Note 1. Achnanthes subsessilis Ehrenb. VanLandingham (p. 65). cites Kütz. 1833 as the correct authority, rather than Ehrenb.1838

Note 2. Achnanthes trinodis (W.Sm.) Grunow Original author given as Arnott (1861). VanLandingham (p. 68). cites W. Sm.1856 (Navicula trinodis) as the earliest name, rather than Arn. 1861 (Achnanthidium trinode)

Note 3. Achnanthidium cryptocephalum Nägeli ? = Achnanthes minutissima var. cryptocephala Grunow VanLandingham  (p. 72). shows Achnanthidium cryptocephalum Nägeli in synonymy with Achnanthes delicatula (Kütz.) Grunow. This latter taxon does not, however, appear to be the same one Grunow has illustrated here under Achnanthes minutissima var. cryptocephala Grunow. The attribution Nägeli ? is probably therefore in error in Van Heurck.

Note 4. Actinoptychus ? annulatus (G.C. Wall.) Grunow  noted as"genus novum ?"

Note 5. Actinoptychus ? annulatus var. ? minor Grunow  noted as "genus novum ?"

Note 6. Amphiprora alata (Ehrenb.) Kütz. Van Heurck's errata (index vol., p 115) show that Pl. 22, fig. 11, 12 are for Amphiprora alata, while fig. 14. is  for A. mediterranea

Note 7. Amphiprora mediterranea Grunow = Plagiotropis mediterranea Grunow.  Van Heurck's errata (index vol., p 115) show that Pl. 22, fig. 11, 12 are for Amphiprora alata, while fig. 14. is for A. mediterranea>.

Note 8. Amphiprora vitrea W.Sm. = Plagiotropis vitrea (W.Sm.) Grunow Van Heurck in error gives author as A.Schm. [A.W.F.Schmidt]

Note 9. Amphora acutiuscula Kütz.  Van Heurck (Texte p. 225) corrects figure number from 13 to 18

Note 10. Amphora angularis W.Greg. This figure (Pl 1, fig. 21) is given in Atlas as A. angularis var. hybrida Grunow.

Note 11. Amphora angulosa var. hybrida Grunow = Amphora angularis var. hybrida Grunow Van Heurck (errata, index volume p. 115) corrects name from Amphora angulosa to A. angularis.

Note 12. Amphora ocellata Donkin  Atlas gives this as A. ocellata Donkin f. minor.

Note 13. Anomoeoneis  A note in Atlas (caption page for Plate 12) refers to figs 1-3 as belonging to Pfitzer's "groupe Anomoeoneis"

Note 14. Bacteriastrum varians Lauder = Chaetoceros varians (Lauder) Van Heurck  Van Heurck,Texte indicates that he follows Kitton in rejecting Bacteriastrum as a genus, retaining it instead as a subgenus of Chaetoceros.

Note 15. Berkeleya dilwynii (C.Agardh) Van Heurck  In Atlas, Grunow is shown as the combining author.

Note 16. Berkeleya micans (Lyngb.) Van Heurck.  In the Atlas, Grunow is given as combining author.

Note 17. Biblarium leptostauron Ehrenb. ? = Fragilaria harrisonii (W.Sm.) Grunow  Van Heurck (index vol., p. 116) corrects spelling of genus from Bibliarium to Biblarium

Note 18. Biddulphia antediluviana (Ehrenb.) Van Heurck = Triceratium antediluvianum (Ehrenb.) Grunow   Van Heurck prefers Biddulphia over Triceratium in Texte ( p. 207) but not in Atlas.

Note 19. Biddulphia aurita var. minima [i.e. miniscula?] Grunow  The last item in the list of captions repeats the number 12. The correct figure number for this taxon should be 14.  Figure 11 matches Van Heurck (1896)  Pl. 20 (633, lower figure) which is called there var. minuscula Grunow.

Note 20. Biddulphia aurita var. minima Grunow  In Atlas this figure is identified. as var. miniscula Grunow, but Van Heurck's (1896) Pl. 20, fig. 632 matches Atlas Pl. 98, fig. 10 and is identified (1896) as var. minima Grunow. Van Heurck Texte (p. 205) has two entries for var. minima. One is probably intended as var. minuscula. See also errata (Texte p. 225).

Note 21. Biddulphia baileyi W. Sm. = Biddulphia mobiliensis (Bailey) Grunow In Texte (p. 205), Van Heurck gives B. baileyi as the correct name, but the combination B. mobiliensis (Bailey) Grunow which Van Heurck gives in the Atlas appears correct based on rules of nomenclature.

Note 22. Biddulphia ? cristata Grunow Van Heurck  Note (index volume, p.116) shows that Grunow [1884] established the genus Odontotropis for this taxon, with the name O. cristata (Grunow) Grunow.

Note 23. Biddulphia discigera Grunow  This figure resembles one of those given for Odontella in Round et al. (1990).

Note 24. Biddulphia favus (Ehrenb). Van Heurck = Triceratium favus Ehrenb.nbsp; Van Heurck makes this combination in Texte (p.208), but not in the Atlas.In Round et al. (1990),  Triceratium favus is given as the type species of the genus Triceratium. I chose to resolve the conflict in Van Heurck by following Round et al (1990).

Note 25. Biddulphia granulata Roper  The reference given in Texte (p. 206) to Atlas Pl. 101, fig. 4, appears to be incorrect for this species, since the caption in Atlas for Plate 101, Fig. 4 is given as B. mobiliensis, a different species.

Note 26. Biddulphia laevis W. Sm. nec Ehrenb. = Navicula laevis Ehrenb. VanLandingham does not list this synonym, nor does Van Heurck  (Texte p. 206)

Note 27. Biddulphia radiata Roper = Biddulphia smithii (Ralfs) Van Heurck   The Atlas and Texte are in conflict. VanLandingham (p. 550). gives the combination B. radiata (W.Sm.) Roper as a synonym of Cerataulus smithii Ralfs, which Van Heurck calls Biddulphia smithii (Ralfs) Van Heurck.

Note 28. Biddulphia turgida W. Sm. = Cerataulus turgidus Ehrenb. Van Heurck uses Biddulphia turgida in Texte, but Cerataulus turgidus in Atlas. The latter is regarded now as correct (Round et al. 1990). I have chosen to resolve the conflict in Van Heurck by following Round et al.

Note 29. Biddulphia weissflogii C.Janisch  Van Heurck (index volume, p. 116) corrects author from Grunow to C.Janisch.

Note 30. Ceratoneis arcus (Ehrenb.) Kütz.  In Atlas the name Kütz. is in parentheses.

Note 31. Cestodiscus obscurus A.W.F.Schmidt  This appears to be a printing error forCoscinodiscus obscurus A.W.F.Schmidt

Note 32. Cestodiscus radiatus Ehrenb.  Van Heurck notes this as a printing error for Coscinodiscus radiatus Ehrenb.

Note 33. Cestodiscus [sic] sol G.C.Wall.  Van Heurck corrects this to Coscinodiscus sol G.C.Wall.

Note 34. Chaetoceros paradoxum var. subsecunda Grunow   Van Heurck corrects the name from Ch. distans var. subsecunda to Ch. paradoxum var. subsecunda (index vol., p. 116)

Note 35. Chaetoceros varians (Lauder) Van Heurck  Van Heurck follows Kitton in rejecting Bacteriastrum as a genus but retains it as a subgenus of Chaetoceros.

Note 36. Climacidium [sic] frauenfeldii [sic] Grunow This name appears to be an error as VanLandingham notes (p. 759). The illustration Pl. 106, fig. 5 in the Atlas is identical to the illustration (p.462, fig. 193) in Van Heurck 1896, which bears the name Climacodium frauenfeldianum. Grunow. The name Climacidiumis considered a synonym for Eunotia, to which the specimen figured in Atlas Pl. 106, fig.5 clearly does not belong.

Note 37. Climacodium frauenfeldianum Grunow  The name of the genus was given in error as Climacidium and the epithet misspelled as frauenfeldii. See note 36.

Note 38. Cocconeis consociata Kütz. = Cocconeis scutellum f. parva Grunow In errata (index vol. p 115), Van Heurck corrects the spelling of the epithet of the synonym from consosiata (as given in the Atlas) to consociata.

Note 39. Colletonema lacustre (C.Agardh) Kütz.  In Texte (p. 111) the author is given incorrectly as (C.Agardh) Van Heurck.  Kützing (1849, p. 105) gives himself as author of the combination Colletonema lacustre, with Schizonema lacustre C.Agardh as synonym. Proper nomenclatural usage would then make the name Colletonema lacustre (C.Agardh) Kütz.

Note 40. Colletonema neglectum (Thwaites) W.Sm. partim = Schizonema neglectum Thwaites   In the Atlas the author is given, incorrectly, as Thwaites (W.Sm., partim)

Note 41. Coscinodiscus ? elongatus Grunow  This is almost identical to what Grunow calls Actinocyclus? elongatus  on the, same plate.

Note 42. Coscinodiscus lineatus Ehrenb.  The author is given in error as Ehrenb. (Kütz.) in Texte.

Note 43. Coscinodiscus minor Anglor. nec Ehrenb. = Coscinodiscus decipiens Grunow   VanLandingham could not find reference to "Anglor" in the literature. Possibly this is simply a gross typographical error for Auctor which could then mean an author other than Ehrenberg or perhaps The Author [Grunow or Van Heurck], not Ehrenberg

Note 44. Coscinodiscus normanii W.Greg. = Coscinodiscus subtilis var. normanii (W.Greg.) Van Heurck   Van Heurck (index vol. p 117) corrects spelling of epithet from normannicus to normanii.

Note 45. Coscinodiscus radiatus Ehrenb.  In errata (index volume, p. 117) Van Heurck says to read Coscinodiscus before fig. 5 in the caption. I interpret this as applying also to figures 4 and 6 which follow fig. 5 on the caption page.

Note 46. Coscinodiscus radiatus var. irregularis Grunow  In errata (index volume, p. 117) Van Heurck says to read Coscinodiscus before fig. 5 in the caption. I interpret this as applying also to figures 4 and 6 which follow fig. 5 on the caption page.

Note 47. Coscinodiscus sol Wallich ?  In errata (index volume, p. 117) Van Heurck says to read Coscinodiscus before fig. 5 in the caption. I interpret this as applying also to figures 4 and 6 which follow fig. 5 on the caption page.

Note 48. Coscinodiscus subtilis (Ehrenb. ?) Grunow  I am not certain why this species was included, since Van Heurck does not report it for Belgium, nor is it illustrated in the Atlas.

Note 49. Coscinodiscus sp. [Van Heurck]  The note in the caption says simply "indéterminé"

Note 50. Craspedodiscus stella Ehrenb. ? = Hyalodiscus stelliger Bailey   In the errata (index vol, p. 116) Van Heurck corrects spelling of generic name Craspepodiscus to Craspedodiscus

Note 51. Cyclotella kützingiana Thwaites  Chauvin, an author not cited elsewhere in connection with this oft-reported species is given as combining author. Grunow puts Thwaites in parentheses. Van Heurck does not refer to Atlas Plate 94, Fig. 5, in the Texte. In the Atlas this specimen is referred-to as an abnormal form.

Note 52. Cyclotella meneghiniana var. rectangulata (Bréb.) Grunow This taxon is referred-to in Texte (p. 214, under the species) but the illustrations in the Atlas are not mentioned in the Texte.

Note 53. Cyclotella operculata (C.Agardh) Kütz. Kützing  (1844) gives  Frustulia operculata Ag. as basionym.

Note 54. Cyclotella operculata var. mesoleia Grunow   Van Heurck appears to include var. mesoleia under the nominate, but still mentions it in the discussion of the species in Texte as a separate entity.

Note 55. Cyclotella operculata var. radiosa Grunow = Cyclotella comta var. radiosa Grunow  Van Heurck refers to ???C. operculata var. radiosa??? under C. operculata in Texte (p. 214) but also on the same page seems to give it as  C. comta var. radiosa 

Note 56. Cyclotella stelligera (Cleve et Grunow) Van Heurck Since Cleve et Grunow reported this as C. meneghiniana var. stelligera, the author of the present combination appears to be Van Heurck

Note 57. Cyclotella striata var. ? stylorum (Brightw.) Grunow  This taxon is neither described nor illustrated in the present work, but is reported in Texte as being found in Type 474

Note 58. Diatoma anceps (Ehrenb.) Grunow   This is now usually given as D. anceps (Ehrenb.) Kirchn.

Note 59. Diatoma ehrenbergii Kütz. = Diatoma elongatum var. ehrenbergii (Kütz.) Van Heurck This also mentioned in caption for Pl. 50, fig. 10-13 as being similar, but not identical, to D. tenue var. hybrida Grunow

Note 60. Diatoma vulgare var.β linearis W.Sm. = Diatoma vulgare var. linearis Van Heurck Others give the synonym simply as var.β W.Sm.

Note 61. Epithemia gibba [var. ?] This illustration was not referrred-to in text and shows only the middle portion of a valve with what appears to be a more or less medial canal. Whatever it is, this specimen appears to lie in an unusual position for an E. gibba, which is now considered a species of Rhopalodia, whose canal is almost never observed in so central a position due to the structure of the valve.

Note 62. Epithemia gibba var. ventricosa Grunow  In errata (index vol., p. 116) Van Heurck corrects the spelling of the epithet from ventricosum to ventricosa

Note 63. Epithemia hyndmanni W.Sm.  There appears to be some doubt about the spelling of the epithet. Van Heurck (index vol., p. 115) corrects hyndmanni to hyndmanii. VanLandingham (p. 1451) gives hyndmanii (hyndmannii).

Note 64. Epithemia intermedia Hilse = [?] Epithemia argus var. amphicephala Grunow  The capition shows E. alpestris W.Sm. in synonymy but also notes that E. intermedia Hilse is similar to E. alpestris W.Sm.

Note 65. Epithemia turgida (Ehrenb.) Kütz. "contenu cellulaire d'après M. Pfitzer"

Note 66. Epithemia turgida var. westermanni (Ehrenb.) Grunow  While Kützing (1844) transferred the taxon from Navicula to Epithemia at the species level (hence the combination Epithemia westermanni (Ehrenb.) Kütz.), it was Grunow (1862) who changed its status to that of a variety in another species of Epithemia, hence Epithemia turgida var. westermannii (Ehrenb.) Grunow.

Note 67. Epithemia westermannii (Ehenb. ?) Kütz. = Epithemia turgida var. westermannii (Ehrenb.) Grunow  Kützing (1844) gives the basionym as Navicula westermani Ehrenb. (1833). Kützing made the combination Epithemia westermanni in 1844.

Note 68. Eunotia falx W.Greg. = Pseudoeunotia hemicyclus (Ehrenb.) Grunow  The author of E. falx is given incorrectly as Grev.

Note 69. Eunotia gracilis (Ehrenb.) Rabenh. Van Heurck (index vol., p 116) indicates that the superfluous "Eunotia" in the caption should be stricken from the caption (i.e. making E. gracilis, not E. Eunotia gracilis)

Note 70. Eunotia polyglyphis var. hexaglyphis (Ehrenb.) Grunow  This is somewhat of a muddle, both nomenclaturally and systematically. Grunow erected the species E. polyglyphis without description or a named or implied nominate variety. The caption for Atlas Pl. 34, fig. 33, indicates that Ehrenberg's E. tetraglyphis, E. pentaglyphis and E. hexaglyphis are considered by Grunow to be part of the proposed species E. polyglyphis Grunow. Later authors, e.g. Hustedt in Rabenhorst (1932) and Patrick and Reimer (1966), have regarded all these entities as variants of the same species. Hustedt (1932) employs the name E. polyglyphis Grunow.  Patrick and Reimer reject this as an invalid name for reasons noted above and emend Ehrenberg's description of E. hexaglyphis to include those forms described by Ehrenberg as E. tetraglyphis and E. pentaglyphis.

Note 71. Eunotia praerupta Ehrenb.  Van Heurck (Texte p. 225) corrects spelling of specific epithet from proerupta to prarerupta

Note 72. Eunotia praerupta Ehrenb. [?]   Van Heurck refers to this specimen thus "forme voisine de l' Eunotia praerupta var. inflata (f. 17) se rapprochant davantage de la var. genuina"

Note 73. Eunotia praerupta var. inflata f. curta Grunow  Van Heurck refers to this figure as E. praerupta f. curta

Note 74. Fragilaria brevistriata Grunow As Patrick and Reimer (1966) note, since the taxon F. brevistriata var. brevistriata Grunow was not described until 1885, all of the varieties of F. brevistriata listed on Plate 45 of the Atlas are nomenclaturally invalid.

Note 75. Fragilaria brevistriata var.? lapponica Grunow = Fragilaria lapponica Grunow   Considered as a variety of F. brevistriata, this name would appear to be invalid for reasons noted in Note 74.

Note 76. Fragilaria brevistriata var. mormorum Grunow  Invalid name. See note 74.

Note 77. Fragilaria brevistriata var. pusilla Grunow Invalid name. See note 74.

Note 78. Fragilaria brevistriata var. subacuta Grunow  Invalid name for reasons given in note 74. Also, Van Heurck (Texte p. 157) assigns the specimen shown to Fragilaria brevistriataGrunow, that is, to the implied nominate variety.

Note 79. Fragilaria brevistriata var. subcapitata Grunow  Invalid name. See note 74.

Note 80. Fragilaria capucina var. acuta (Ehrenb.) Rabenh.   The author of this combination is given incorrectly as Grunow.

Note 81. Fragilaria crotonensis Kitton  The author of this combination is given incorrectly as (A.M.Edwards) Kitton.

Note 82. Fragilaria virescens Ralfs  "contenu du frustule d'après Borscow".

Note 83. Gaillonella biseriata Ehrenb.[1842] = Melosira arenaria Moore Ehrenb.   The date 1842 is significant, the usage in Ehrenb. 1854 being different.

Note 84. Gaillonella nummuloides (Dillwyn) Bory = Melosira nummuloides (Dillwyn) C.Agardh  Bory was the combining author, not the author of the basionym.

Note 85 Gaillonella varians Ehrenb. [1838, in part] = Melosira arenaria Moore Ehrenb.  The date is significant because of a difference in usage in Ehrenb. 1838 from that in Ehrenb. 1836.

Note 86. Gomphonema angustatum (Kütz.) Rabenh.  The author is given in error as Kütz. alone.

Note 87. Gomphonema dichotomum β sessile Kütz. [pro parte ?, sensu Grunow in Van Heurck 1880] = Gomphonema montanum var. subclavatum Grunow  In Kützing (1844),   Taf. 13 (I) 6 illustrates G. dichotomum β sessile by three specimens drawn in situ. Two of these (the pair on the right in the group, both in girdle view) are clearly some form of Gomphonema. The figure on the left, in valve, view does not appear to resemble a Gomphonema, at least not that called G. montanum var. subclavatum Grunow..  Kützing (1844, 2er Abdruck 1865,  p. 86) further places Exilaria truncata Kütz. (1833) in synonymy with G. dichotomum β sessile. Van Landingham (p. 1644) places Exilaria truncata Kütz. (1833)  in synonymy with Synedra vaucheriae var. truncata (Grev., Ralfs in Pritchard 1861) Rabenh. 1864. The specimen illustrated in the left-hand figure in Kütz. 1844 (1865), Taf. 13 (I) 6, is in valve view and appears more or less linear and symmetric to both longitudinal and transverse valve axes and thus could well be a Synedra or Fragilaria. , but I think the other two cells could not. If Kützing had a "gomphonemoid" taxon in mind when he described Exilaria truncata, the left-hand specimen in Kütz. 1844 (1865) Taf. 13 (I) 6 would not appear to be the same thing. The pair of cells shown in girdle view, on the other hand, would be difficult to assign beyond genus.

Note 88. Gomphonema exiguum Kütz. var. minutissima (Kütz.) Grunow  In the caption to Plate 4, fig. 8, Van Heurck in error lists the species as Stauroneis anceps var. linearis Grun. [i.e. Grunow]

Note 89. Gomphonema gracile var. auritum (A.Braun) Van Heurck Van Heurck in errata (index vol., p. 115) corrects the range of figures for this taxon from 15,18 to 15-18.

Note 90. Gomphonema olivaceum (Lyngb.) Kütz.  The author is given in error as Ehrenb. in the Atlas.

Note 91. Gomphonema olivaceum var. ? subramosum (C.Agardh. ?) Grunow  Reference is made (!) to Küzting's specimen.

Note 92. Gomphonema subramosum C.Agardh. ? = Gomphonema olivaceum var. ? subramosum (C.Agardh) Grunow  Reference is made (!) to Küzting's specimen.

Note 93. Gomphonema subtile f. augusta [sic] Grunow  Forma augusta may possibly be a misprint for f. angusta, but in any case Van Heurck (1896)  considered this figure to represent part of the nominate form.

Note 94. Gomphonema tenellum Kütz. The caption has the note "nec W.Sm."

Note 95. Goniothecium rogersii Ehrenb. = Gomphonema odontella (var.? f. ?) The author of the caption  mentions Goniothecium rogersii Ehrenb. in the caption to Goniothecium odontella var. danica (Grunow) Grunow, noting that (G. rogersii Ehrenb.) is also a form ("une forme") of Goniothecium odontella.

Note 96. Grammatophora angulifera var. australiensis Grunow = Grammatophora angulosa var. australiensis Grunow  The specific epithet angulifera  is noted by Van Landingham (p.1967) as probably a typographical error forangulosa

Note 97. Grammatophora marina var. tropica (Kütz.) Grunow  Van Landingham (p. 1978) gives the combining authors as Cleve et Möller

Note 98. Grammatophora oceanica var. novae-zeelandiae Grunow = ? Grammatophora marina var. macilenta (W.Sm.) Van Heurck  This figure is called by Van Heurck (Texte p. 164) Grammatophora marina var. macilenta (W.Sm.) Van Heurck.

Note 99. Hantzschia amphioxys (Ehrenb.) Grunow  The specific epithet is misspelled amphyoxis here and elsewhere.

Note 100. Hyalodiscus franklini (Ehrenb. ?) Grunow = Hyalodiscus scoticus (Kütz.) Grunow  This name may be a confusion of Podosira franklini Grunow (= Hyalodiscus scoticus (Kütz.) Grunow) and Hyalodiscus franklini Cleve (a synonym of Hyalodiscus subtilis Bailey). Another synonym of Hyalodiscus subtilis Bailey is Craspedodiscus franklini Ehrenb. To further complicate matters, a note, presumably written by Grunow, in the caption to Atlas Pl. 84, fig. 15-17, (Hyalodiscus scoticus (Kütz.) Grunow) refers to this as "une petite form d' H. subtilis" The name may therefore also represent a new combination, promptly scrapped in favor of H. scoticus.

Note 101. Isthmia nervosa Kütz.  This species is indicated as being found in Type 485.

Note 102. Licmophora gracilis (Ehrenb.) Grunow  The author is given in error as (Kütz.) Grunow

Note 103. Licmophora hyalina (Kütz.) Grunow  Van Heurck (index vol. p. 116) corrects the legend D. hyalina to L. hyalina

Note 104. Liparogyra dendroteres Ehrenb. = Melosira roeseana var. dendroteres (Ehrenb.) Grunow  The epithet dendroteres is uniformly misspelled dentroteres in Van Heurck.

Note 105. Mastogloia dansei var. elliptica (C.Agardh) Grunow  In the Texte (p. 70) this variety is mentioned,  but without description.

Note 106. Melosira binderana Kütz. = Melosira crenulata f. binderana (Kütz.) Van Heurck  The epithet binderana is uniformly misspelled binderiana in both Texte and Atlas. I have seen Kützing 1844 (2er Abdruck 1865). There, species 14 is Melosira italica (Ehrenb.) Kütz.  M. crenulata is given under the same number as β Melosira crenulata and M. binderana is given as γ Melosira binderana

Note 107. Melosira borreri var. octagona [author?]  This taxon is mentioned in the caption to the illustration for Melosira juergensii var. subangularis Grunow (Pl. 86, fig. 9)

Note 108. Melosira crenulata var. italica (Ehrenb.) Grunow  The author is given in error as (Kütz.) Grunow

Note 109 Melosira granulata var. decussata Grunow  The note in the caption reads "passant en partie à la var. decussata"

Note 110. Melosira granulata var. jonensis f. curvata Van Heurck?  The caption for this illustration does not carry the asterisk (*) indicating Grunow as illustrator (and presumed author). Van Landingham (p. 2208) names Grunow.

Note 111. Melosira granulata var. jonensis f. procera Van Heurck?  The caption for this illustration  does not carry the asterisk (*) indicating Grunow as illustrator (and presumed author). Van Landingham (p. 2208) names Grunow.

Note 112. Melosira juergensii var. octogona Grunow = Melosira juergensii var. subangularis Grunow   In Texte (p. 199), Van Heurck refers to this as a synonym of M. juergensii var. subangularis Grunow [in Van Heurck 1882].

Note 113. Melosira lineata (Dillwyn) C.Agardh = Melosira borreri Grev.  The author of the synonym is  given as C.Agardh alone.

Note 114. Melosira lyrata (Ehrenb.) Kütz. Spelling of specific epithet according to Kützing 1844 is lirata. Also, the author is given in error in the Atlas as (Ehrenb.) Grunow.

Note 115. Melosira moniliformis (O.F.Müll.) C.Agardh = Melosira borreri Grev.  The author of the synonym is given as C.Agardh alone.

Note 116. Melosira nummuloides (Dillwyn) C.Agardh  The author is given in error as (Bory) C. Agardh.

Note 117. Melosira nummuloides Ehrenb. [?]  No such combination could be found. It appears rather to be a confused combination of Melosira hormoides Mont. and Podosira nummuloides Ehrenb. both of which have been referred to Podosira hormoides (Mont.) Kütz., which is given in error in the Atlas as Podosira hormoides Mont.

Note 118. Melosira roeseana var. dendroteres (Ehrenb.) Grunow   Grunow notes that various forms (normalis, elongata, spiralis and porocyclia) are all found together with all intermediates in some habitats. I do not believe therefore that Grunow intended to use these words as names of taxa. If so considered (i.e. f. normalis Grunow, f. elongata Grunow, f. spiralis Grunow and f. porocyclia Grunow) they would perhaps invalidate the combination M. roeseana var. dendroteres (Ehrenb.) Grunow for which no nominate forma (f.) was designated.

Note 119. Melosira varians C.Agardh  The caption for fig. 9 is absent.

Note 120. Meridion circulare (Grev.) C.Agardh ?  The note in the caption for this figure reads "forme intermediaire entre M. circulare et M. constrictum"

Note 121. Meridion circulare var. constrictum (Ralfs) Van Heurck ? The note in the caption for this figure reads "forme intermediaire entre M. circulare et M. constrictum"

Note 122 Micromega floccosum Kütz. = Schizonema Kützingii Rabenh.  Micromega floccosum Kütz. was, according to Kützing 1844 (1865 printing), based on an unpublished name Schizonema floccosum, "Rudolphi, ined." given to specimen(s) found in Binder's herbarium. Also in Kützing 1844 (1865 printing), one finds the name Schizonema floccosum Kütz. for a different species. When both Micromega and Schizonema were accepted as separate genera, as Kützing did in 1844, there was no nomenclatural difficulty. When Micromega was abandoned in favor of Schizonema, both species would have had the epithet "flocculosa" in the same genus. Rudolphi's Schizonema floccosum was an invalid name. Kützing's Schizonema floccosum was valid. The validly named Micromega flocculosa Kütz. was renamed when it was transferred to Schizonema. The new name was Schizonema kützingii Rabenh.

Note 123. Navicula ambigua f. craticula Van Heurck  In the Atlas this is given as "N. ambigua, forme craticulaire"

Note 124. Navicula aspera Ehrenb.  The Texte incorrectly gives the illustration number as Suppl. fig 27

Note 125. Navicula atomoides [?] Grunow = Navicula minima Grunow ?  The note in the caption to this illustration is "forme moyenne entre le N. atomoides et le N. minima"

Note 126. Navicula atomus (Autor nec Kütz.) = Navicula muralis f. minuta Grunow   For reasons given in Note 128 (N. atomus Nägeli) "Autor" is probably Van Heurck rather than Grunow, and the name "f. minima" should perhaps be ascribed to Van Heurck.

Note 127. Navicula atomus formae tenuistriatae Grunow In the index volume, p. 115, Van Heurck corrects the spelling of the epithet from tenustriata to tenuistriata. The caption for the figure, however, gives "[N. atomus] formae tenustriatae. The note in the errata suggests that the intended name was probably Navicula atomus f. tenuistriata [Grunow]

Note 128. Navicula atomus Nägeli [sic]  Perhaps better given as N. atomus (Kütz.) Grunow, as noted in VanLandingham (p 2442). Kützing described Amphora ? atomus in 1844; in 1849 he listed Synedra atomus Nägeli in litt. = Amphora atomus Kütz. [1844], the latter evidently intended by Kützing (at least. by 1849) as a synonym. There is no listing in Kützing 1849 for Amphora atomus in the section on the genus Amphora. Of the group of illustrations of A. atomus (Taf. 30 fig. 70) in Kütz. 1844, the last could possibly be one of the smallAmphorae. The others look more like minute Naviculae. None match the current circumscription of Synedra, or indeed, I think, that given in Kützing 1849. Grunow (1860) apparently made the combination Navicula atomus (Kütz.) Grunow. The synonymy given for Navicula atomoides Grunow (Van Heurck Atlas Pl. 14 fig. 12) is doubly puzzling:: "N. atomus Autor. nec Kg." If the "Autor" in question is Grunow (who drew the figure), then the "nec Kg." collides with N. atomus (Kütz.) Grunow (1860) as given in VanLandingham. This would make N. atomus Grunow in Van Heurck an unlikely choice of names by Grunow. If "Autor" refers to Van Heurck, it is again odd, considering that Pl. 14, fig. 24, is given as N. atomus Naegeli, Kütz. in the Atlas and N. atomus Naeg. in text. There is no listing in Van Landingham for either Navicula atomus Grunow or Navicula atomus Van Heurck. Today N. atomoides Grunow (Atlas Pl. 14  fig.12) is regarded as the same as N. minima Grunow, while N. atomus Grunow (Atlas Pl. 14 fig.15) is, as noted in Patrick and Reimer 1966, given properly as N. atomus (Kütz.) Grunow. The Grunow in Van Heurck illustration (Atlas Pl. 14 fig. 24) is referred-to neither in VanLandingham nor in Patrick and Reimer 1966, though both make reference to the species Synedra atomus Naeg. in litt. reported in Kütz. 1849, which is apparently what Van Heurck (in the Texte) calls Navicula atomus Naegeli and which Grunow (if it were he who wrote the plate caption as well as making the drawing) refers to as N. atomus Naegeli !, Kütz. My guess is that Van Heurck wrote the caption and that the (!) refers to Grunow's specimen. The "Autor" would thus be Van Heurck and as noted, N. atomus Van Heurck appears to be a nomen nudum.. Such a lot of ink to have spilled on such a wretched group of organisms.

Note 129. Navicula bottnica Grunow   The last entry on caption page misprinted 23, but should be 33

Note 130 Navicula brevis W.Greg.  Atlas caption adds the words "magis typica"

Note 131. Navicula cincta f. minuta Van Heurck This taxon is given in the Texte, but without illustration, description or Type number.

Note 132. Navicula cryptocephala var. intermedia Van Heurck  Variety  intermedia is mentioned in Texte (p. 84) without illustration number.

Note 133. Navicula cryptocephala var. veneta (Kütz.) Rabenh.  In Texte this is reported as illustrated by both fig. 3 and fig. 4. In Atlas the caption for fig. 4 says that it is the same as fig. 2, i.e. N. cryptocephala var. exilis

Note 134. Navicula dicephala Ehrenb.  Author given as W.Sm. but should be Ehrenb.

Note 135. Navicula falaisensis Grunow  In errata (index vol. p. 115) Van Heurck corrects the spelling of the epithet from falaisiensis to falaisensis.

Note 136. Navicula formosa W.Greg.  The caption adds the word "typica". I think this was a descriptive remark, not a formal name.

Note 137. Navicula gracilis Ehrenb.  The Texte gives the author incorrectly as Kütz. The caption for the figure in the Atlas errs in giving the author as (Ehrenb.) Kütz.

Note 138. Navicula kamorthensis Grunow   This species is mentioned in the caption for Pl. 11, fig. 20, (Navicula humerosa Bréb. )

Note 139. Navicula lamprocampa Kütz. ? = Nitzschia lamprocampa Hantzsch  Kützing's illustration (1844 Taf. 4, fig. V (4)) looks like a Nitzschia of some sort. Taf. 4 fig V (1-3) are shown with a sigmoid raphe along the center line of the valve and perhaps represent a Pleurosigma or Gyrosigma.

Note 140. Navicula lanceolata f. curta Grunow  The Texte gives the illustation number as to Pl. 7, fig. 17, but should read Pl. 8, f. 17.

Note 141. Navicula lata var. minor W.Greg.  The Texte indicates this as present in Type no. 63 and refers to it as intermediate between N. borealis Ehrenb. and N. lata Bréb. There is neither illustration nor further description.

Note 142. Navicula lyra Ehrenb.  In Atlas the terms "elliptica" for fig. 2 and "typica" for fig. 1 are evidently intended as descriptions, not names.

Note 143. Navicula menisculus var. upsalensis Grunow = Navicula peregrina var. menisculus f. upsaliensis (Grunow) Van Heurck In the index vol. (p. 115) Van Heurck says that N. upsaliensis should be read as N. upsalensis. However this taxon is actually named in the Texte as Navicula peregrina var. menisculus f. upsaliensis, with the "i" again inserted.

Note 144. Navicula minima [?] Grunow  Note in caption reads "forme moyenne entre le N. minima et le N.atomoides"

Note 145. Navicula molaris Grunow   The figure is misnumbered 20 in the caption.

Note 146. Navicula mutica Kütz. [?] = Navicula mutica var. goeppertiana (Bleisch) Grunow   The caption reads "type original du Navicula mutica Kütz."

Note 147. Navicula ostrearia (Gaillon) Bory = Navicula fusiformis var. ostrearia (Gaillon) Grunow  The author is given as Turpin nec Bréb., but Van Landingham (p. 2706) gives the basionym as Vibrio ostrearius Gaillon 1820 and shows the combination as Navicula ostrearia (Gaillon) Bory 1824. Turpin's figure is indicated as published in 1828.

Note 148. Navicula parva (Ehrenb.) Ralfs = Navicula stauroptera var. parva Grunow The caption is misnumbered Plate 6  fig. 5.

Note 149. Navicula permagna (Bailey) A.M.Edwards  The original author is given in Texte and Atlas as Bailey. The basionym is Pinnularia permagna Bailey.

Note 150. Navicula polyonca Bréb.  In the key to species (Texte p. 75) the name is given in error as N. mesolyta

Note 151. Navicula rabenhorstii Grunow   The Texte indicates that this species is present in Type no. 63 and notes that it is intermediate between N. borealis Ehr. and N. lata Bréb. The name is given Without illustration or further description.

Note 152. Navicula schumanniana Grunow   In Texte (p. 225) Van Heurck corrects spelling of specific epithet from schumaniana to schumanniana

Note 153. Navicula serians Bréb.  In the Atlas the author is given as (Bréb.) Kütz.. Van Landingham (p. 2796) gives the author as Bréb. in Kütz.

Note 154. Navicula serians var. brachysira Van Heurck  The figure number in Texte is misprinted as 126, which is actually the Type number.

Note 155. Navicula splendida W.Greg.  In discussion of Navicula bomboides the illustration for N. splendida is given as Pl. 5 fig. 14, but should have been given as Pl. 9, fig. 4.

Note 156. Navicula thuringiaca Kütz. = Pleurosigma angulatum (J.T. Quekett) W.Sm. Van Heurck gives the combination Pl. thuringiaca [(Kütz.) Ralfs] (corrected to Pl. thuringiacum on p. 115, index vol.) as being the proper name, but rejects it in favor of the later, but better known, name Pl. angulatum. Patrick and Reimer (1966, p. 332) note that Kützing placed Frustulia attenuata Kütz. ex parte (1833) in synonymy with his N. thuringiaca (1844). Patrick and Reimer note further that the Kützing material for F. attenuata does not appear to contain specimens corresponding to what Kützing figured as N. thuringiaca. They concluded that retention of the name Pl. angulatum (J.T. Quekett) W.Sm. was preferable to changing it "on quite dubious grounds."

Note 157. Navicula trevelyana Donkin  The illustration should only be fig. 6, not fig. 5, 6 as given in Texte.

Note 158. Navicula tuscula Ehrenb.  The author is given as (Ehrenb.) Grunow in the Atlas.  Ehrenberg seems to have used both Pinnularia and Navicula as generic names for this species in 1840 (41) but most authorities accept Navicula as prior.

Note 159. Nitzschia amphibia var. acutiuscula Grunow  The varietal epithet is corrected (index vol. p 116) from actiuscula to acutiuscula

Note 160. Nitzschia amphioxys W. Sm. = Hantzschia amphioxys (Ehrenb.) Grunow  The specific epithet is misspelled amphyoxis for both the name and synonym.

Note 161. Nitzschia closterium Eulenst. = Nitzschia reversa W.Sm.  Grunow  also considers Synedra closterioides Grunow synonymous, but this is not recognized by later authors.

Note 162. Nitzschia distans var. tumescens Cleve et Möller  The author is  given in error as Grunow.

Note 163. Nitzschia fasciculata (Grunow) Grunow  The species Nitzschia sigmoidea has as basionym Bacillaria sigmoidea Nitzsch (1817). William Smith reassigned this species to the genus Nitzschia in 1853 as Nitzschia sigmoidea (Nitzsch) W.Sm. The epithet "sigmoidea" was at that point no longer nomenclaturally available for any other species of Nitzschia. William Smith erected Homoeocladia sigmoidea in 1856 for the species now known as Nitzschia fasciculata. Grunow, in 1878, erected the species Homoeocladia fasciculata. This latter name would, in the genus Homoeocladia, be a synonym for Homeocladia sigmoidea W.Sm. However, when Grunow reassigned his Homoeocladia fasciculata to the genus Nitzschia as Nitzschia sigma var. fasciculata (Grunow 1878 and later), When Grunow (in Van Heurck 1880-1885) revaluated it as a species (Nitzschia fasciculata (Grunow) Grunow), "fasciculata" was the oldest available epithet for the species in the genus Nitzschia.

Note 164. Nitzschia frustulum (Kütz.) Grunow, [partim?] = Nitzschia frustulum var. perminuta Grunow  Van Heurck, in errata  (index vol. p. 116), corrects the name in parentheses in the caption from (N. frustulum Kütz. !) to (S. frustulum Kütz. !). The (!) would seem to indicate that Grunow had seen Kützing's type specimen ofSynedra frustulum (= Nitzschia frustulum (Kütz.) Grunow), though it might mean that he was referring to his own specimen (Grunow in Cleve et Grunow 1880) used in making the transfer of the species from Synedra to Nitzschia. In the first case, the statement might make Nitzschia frustulum var. perminuta Grunow a nomen nudum. In the second case, it might invalidate the combination Nitzschia frustulum (Kütz.) Grunow. A third possibility is that the statement simply indicates that the present taxon belongs to the species N. frustulum (Kütz.) Grunow without asserting that it is the same as the nominate variety.

Note 165. Nitzschia frustulum f. subserians Grunow  This is one of many "idem" notations that is difficult to interpret, referring as it does to the entry N. (frustulum var.) HANTZSCHIANA Rabenh. Some consider the intended combination to be Nitzschia frustulum f. subserians, others Nitzschia hantzschiana f. subserians. One might even argue for N. frustulum var. hantzschiana f. subserians. I have left it in the form shown, without any particular reason for choosing it.

Note 166. Nitzschia frustulum var. perpusilla (Rabenh.) Grunow The author is given in error as Rabenhorst alone.

Note 167. Nitzschia levidensis ? = ? Nitzschia tryblionella var. levidensis (W.Sm.) Grunow  The note in the caption reads "forme se rapprochant du N. levidensis"

Note 168. Nitzschia macilenta W.Greg.  The author is given in error as W.Sm.

Note 169. Nitzschia panduriformis W.Greg   The author is given incorrectly as Grunow

Note 170. Nitzschia panduriformis var. minor Grunow = Nitzschia panduriformis W.Greg.  Van Heurck includes fig. 4 in his list of illustrations for the nominate.

Note 171. Nitzschia romana Grunow  Note in caption to fig. 12 refers to "N. fonticold" which is a tyographical error for N. fonticola.

Note 172. Nitzschia rostrata Grunow = Nitzschia reversa W.Sm.  This is given by Grunow as a synonym of Synedra closterioides Grunow but is not recognized as such by later authors.

Note 173. Nitzschia serians (Bréb.) Rabenh. [sensu Grunow in Van Heurck] = Nitzschia thermalis f. brevis ? Grunow This, I think, is not a correct combination. Brébisson's Frustulia serians is the taxon reported in Patrick and Reimer (1966) as Anomoeoneis serians (Bréb. ex Kütz.) Cleve, and which is given in Kützing (1844) as Navicula serians ( De Brébisson, ex specim.). Grunow's illustration for Plate 59 fig. 23 is clearly a Nitzschia.

Note 174 Nitzschia sigma var. rigida (Kütz.) Grunow  The caption to fig. 3 has note: "petite forme tenant le milieu entre la var. rigida et la var. sigmatella"

Note 175. Nitzschia sigma var. sigmatella (W.Greg.) Grunow  The caption to fig. 2 puts a (?) after the author W.Greg.; caption to fig. 3 has note: "petite forme tenant le milieu entre la var. rigida et la var. sigmatella"

Note 176. Nitzschia sigmoidea (Nitzsch) W.Sm.  Both Texte and Atlas give the author as (Ehrenb.) W.Sm. However, the basionym is Bacillaria sigmoidea Nitzsch (1817). Ehrenberg (1832) placed the species in the genus Navicula as Navicula sigmoidea. William Smith made the transfer to Nitzschia.

Note 177. Nitzschia sinuata var. tabellaria (Grunow) Grunow  The basionym is Denticula tabellaria Grunow

Note 178. Nitzschia stagnarum Rabenh. = Nitzschia stagnorum (Rabenh.) Grunow The epithet stagnarum is a misspelling of stagnorum.

Note 179. Nitzschia stagnorum (Rabenh.) Grunow  The epithet stagnorum is misspelled as stagarum and author given in error as Rabenhorst. The basionym is Nitzschia thermalis var. stagnorum Rabenh. The change in rank was made by Grunow in 1880.

Note 180. Nitzschia tabellaria (Grunow) Grunow = Nitzschia sinuata var. tabellaria (Grunow) Grunow   The basionym is Denticula tabellaria Grunow

Note 181. Nitzschia tenuis Eulenst. = Nitzschia subtilis (Kütz.) Grunow  The author given as W.Sm. ??, but Nitzschia tenuis W.Sm. is a different species, now considered to be Nitzschia tergestina (Kütz.) Ralfs. Van Landingham (p. 3127) notes that the species referred-to in Van Heurck as a synonum of N. subtilis is from Eulenstein (1868) fide De Toni 1892.

Note 182. Nitzschia thermalis (Ehrenb.) Auersw.  The author is given by both Van Heurck and Grunow as (Kütz.) Grunow, making reference to Surirella Kütz. Kützing 1844 reported this taxon as Surirella thermalis. The synonymy Kützing gave indicates that Pinnularia ? thermalis Ehrenb. (1841) may be the oldest published name. (The only earlier name given in Kützing's synonymy was Cymbella minor C.Agardh (1830), which is now considered to be Cymbella cistula (Ehrenb.) Kirchn.) Considered as a species of Surirella, the proper name for the present taxon would be Surirella thermalis (Ehrenb.) Kütz. Auerswald apparently was the first to transfer the species to the genus Nitzschia.

Note 183. Nitzschia vermicularis (Kütz.) Hantzsch  The author is given in error as (Kütz.) Grunow in Texte.

Note 184. Odontella favus Ehrenb. = Triceratium favus Ehrenb.  This equivalence is given in the Atlas, but not in Texte ( p. 208)

Note 185. Paralia sulcata Heib. = Melosira sulcata (Ehrenb.) Kütz.  I could not find reference to Paralia sulcata Heib. in Van Landingham. There is a reference (VanLandingham p. 3178) to Paralia marina (W.Sm.) Heib., a combination referred to as a synonym of Melosira sulcata (Ehrenb.) Kütz.

Note 186. Plagiotropis gibberula Grunow  There are two figures numbered. 11 in the captions to the plate, but, this one should be 12, I believe.

Note 187. Plagiotropis mediterranea Grunow  The caption gives fig. 12, but should, I think, be fig. 14.

Note 188. Plagiotropis vitrea (W.Sm.) Grunow  The original author given in error as A. Schm. [A.W.F.Schmidt]

Note 189. Pleurosigma attenuatum (Kütz.) W.Sm.  Van Heurck's correction (index vol., p. 115) appears to contain an error for the genus (Navicula instead of Pleurosigma). As stated, it reads "[Lisez] Navicula attenuata Kütz. au lieu de var. attenuata Kütz." If one considers this species as a member of the genus Pleurosigma, the correct name would be Pl. attenuatum (Kütz.) W.Sm., as noted in VanLandingham (p. 3362).

Note 190. Pleurosigma eximium (Thwaites) Grunow  The author given in Texte as (Thwaites) Van Heurck, but the species was first described as Schizonema eximium Thwaites (as noted in the capition to Pl. 21, fig. 2) and Grunow  (in Cleve et Grunow 1880) first made the present combination. Hence the name Pleurosigma eximium (Thwaites) Grunow.

Note 191. Pleurosigma obtusatum Sull. et Wormley [sensu Van Heurck] = Pleurosigma eximium (Thwaites) Grunow   Van Heurck says this is synonymous with Endosigma eximium (Thwaites) Bréb., which he refers to in Texte (p 119) as Pleurosigma eximium Van Heurck. Van Landingham does not list Pleurosigma obtusatum Sull. et Wormley as a synonym of the present taxon, but reports it as a species in its own right.

Note 192. Pleurosigma parkeri M.B.Harrison? Van Heurck gives simply M. Harrison (probably the "M" is "Monsieur"). I have seen the original published description and it is titled simply "Communication from Harrison"

Note 193. Pleurosigma rigidum W.Sm.  This species is mentioned in Texte (p. 116) in the discussion of Pleurosigma affine var. nicobarica Grunow.

Note 194. Pleurosigma scalprum (Gaillon in Turpin ) Ralfs   Van Heurck, in caption to Pl 20, fig. 4, gives author as Grunow. He continues, however, noting that Navicula scalprum Gaillon in Turpin is perhaps the same thing: "Nav. scalprum Gaillon et Turpin ?" Van Heurck evidently missed Ralfs as the first to make the present combination and apparently regarded Grunow as having done so. The combination would in this case have been Pleurosigma scalprum (Gaillon in Turpin) Grunow. Van Heurck and Grunow both typically omit the names of all but the combining author of the taxon in question, hence the given combination Pleurosigma scalprum Grunow. A moot point since this taxon is a Gyrosigma.

Note 195. Pleurosigma spencerii var. smithii Grunow  Pleurosigma spencerii W.Sm. is shown as a synonym. This would appear to turn the rules of nomenclature upside down.

Note 196. Podosira hormoides (Mont.) Kütz.  The author is given in error as Kütz. alone.

Note 197. Podosphenia gracilis Ehrenb.  The author is given in error as Kütz.

Note 198. Pterotheca aculeifera Grunow = Pyxilla ?? aculeifera Grunow  Beneath the caption to Plate 83, fig. 10-11 (Pyxilla ?? kittoniana), Grunow made the following note "Pourait bien former un nouveau genre: Pterotheca Grun., auquel on rapporterait aussi les fig. 7, 8, 13 et 14." He suggested that such a genus might be appropriate, but he did not provide a circumscription of the proposed genus, nor did he designate a type species. This was done later by other authors, but at the time the note was written the genus Pterotheca was informally proposed, but not formally erected.

Note 199. Pyxilla ?? aculeifera Grunow  See Note 198.

Note 200. Rhaphoneis amphiceros var. rhombica Grunow    The generic name is misspelled Raphoneis in Texte, but not in Atlas.

Note 201. Rhizosolenia styliformis Brightw.  In errata, Van Heurck (index vol., p 116) corrects the figure numbers in the first line of the caption from 1-2 to 1-3

Note 202. Sceptroneis australis var. ? auklandica Grunow = Trachysphenia australis var. auklandica Grunow  The spelling auklandica is as given in the Atlas.

Note 203. Schizonema albicans (Kütz.) [?]   Plate 15 is credited to Grunow. The name in the caption for Plate 15, fig. 20 is Sch. albicans (Kütz nec Menegh.). The caption continues, referring to Micromega albicans Kütz. as a synonym. It is uncertain which author transferred this species from Micromega to Schizonema. Van Landingham (p. 3643) has, I think, misread the caption. The writer of the caption, presumably Grunow, indicated by (!) that he had seen Kützing's specimen of Micromega albicans. If Grunow meant by (Kütz nec Menegh.) that Schizonema albicans, based on Micromega albicans Kütz (1844), is not the same as Schizonema albicans sensu Meneghini (1845?), this could mean that he felt that Meneghini had misinterpreted his own specimen, or that Meneghini made use of the epithet "albicans" for a new and unrelated species of Schizonema. Kützing continued to employ the name Micromega albicans in Species Algarum (1849). If Grunow was in error, and Meneghini in fact correctly transferred Micromega albicans Kütz. to Schizonema, the name should be Schizonema albicans (Kütz.) Menegh. If Grunow was correct, and especially if he himself in fact made the transfer to Schizonema , the epithet "albicans" should not have been used, since it was already in use for Meneghini's species (Schizonema albicans Menegh.), Kützing's species Micromega albicans would then have required a new name when transferred to the genus Schizonema.

Note 204. Schizonema apiculatum var. fastigiatum (Kütz.) Grunow  The basionym is Micomega fastigatum Kütz. (1849, p. 108). Note spelling of the epithet. In the same description Kützing referred (as a synonym?) to the Schizonema ramosissimum in Berkeley's herbarium.

Note 205. Schizonema araneosum Autor, partim [i.e. sensu Grunow, partim ?] = Schizonema comoides (Dillwyn) C.Agardh  Grunow does not name the original author, but the name is referred-to in Van Landingham (p. 3644) as Schizonma araneosa Kütz. (1844). It is interesting that Kützing, in his description of that taxon, cited as synonyms Conferva araneosa D.Mohr, Conferva comoides Dillwyn, and Schizonema comoides C.Agardh.

Note 206. Schizonema crucigerum W.Sm.  There is an error in numbering on the plate, with "fig. 2" appearing twice.  Van Heurck notes this (index vol. p. 115) and corrects the first "fig. 2" to "fig. 1b" although this drawing actually has no number on the plate.

Note 207. Schizonema hyalinum (Kütz.) Menegh.  The combining author given in error as Rabenhorst.

Note 208. Schizonema myxacanthum var. intermedia Grunow  The index volume (p. 115) corrects the varietal epithet from intermedium to intermedia

Note 209. Schizonema sp. ? [Grunow]   The caption contains the note "Sch. vivant dans les gaines du Berckeleya patens (Kütz.) Grun. et du Sch. comoides Ag."

Note 210. Schizonema torquatum (Harv.) Meneghini  The author is given in error as W.Sm. The writer of the caption, presumably Grunow, indicated that he had seen (!) William Smith's specimen. Van Landingham, (p. 3663), gives the basionym as Schizonema smithii var. torquatum Harv., and (on p. 3662) credits Meneghini as the author of the combination Schizonema torquatum.

Note 211 Sphenella vulgaris Kütz. = [?] Gomphonema olivaceum var. vulgaris Grunow  In the Texte, S. vulgaris is given in text as a synonym of Gomphonema angustatum var. vulgaris Grunow. Kützing's illustration for Sphenella vulgaris (Kützing 1844/1865) does not resemble Atlas Pl 25, fig. 21. Kützing recognizes Gomphonema olivaceum and illustrates it in a way that does not resemble his illustration of Sphenella vulgaris. This latter species was later referred to the genusGomphocymbella as G. vulgaris (Kütz.) O.F.Müll. Grunow's illustration of Gomphonema olivaceum var. vulgaris is clearly that of a variety of Gomphonema olivaceum. I therefore do not feel that Van Landingham (p.1938) was correct in placing Gomphonema olivaceum var. vulgaris Grunow in synonymy with Gomphocymbella vulgaris (Kütz.) O.F. Müll., nor was Van Heurck, in my opinion, correct in indicating Sphenella vulgaris Kütz. as a synonym of Gomphonema olivaceum var. vulgaris Grunow.

Note 212. Stauroneis anceps var. linearis (Ehrenb.) Brun  In the caption to Plate 4, fig. 8, Van Heurck in error lists the species as Stauroneis anceps var. linearis Grun. [i.e. Grunow]

Note 213. Stauroneis legumen (Ehrenb.) Kütz.  The author is given in error as Ehrenberg alone. Kützing 1849 (p. 92), lists himself as author of this combination, citing Stauroptera legumen Ehrenb. as basionym.

Note 214. Stauroneis linearis Ehrenb. = Stauroneis anceps var. linearis (Ehrenb.) Brun   Van Heurck gives the basionym in error as Stauroneis linearis Kütz., but Kützing 1844 (1865 printing) clearly indicates his source as Ehrenberg 1843.

Note 215. Stauroneis spicula W.J.Hickie  In the index volume (p. 115) Van Heurck corrects the author from Dickie to Hickie

Note 216. Stephanodiscus astraea var. [Grunow]  The caption to plate 95, fig. 9, has the note "forme intermediaire entre le St. astraea et la var.minutula"

Note 217. Stephanodiscus hantzschianus [i.e. hantzschii] Grunow  The epithet hantzschianus is not accepted.

Note 218. Stephanodiscus hantzschianus [i.e. hantzschii] var. pusilla Grunow  If recognized, taxon should be named Stephanodiscus hantzschii var. pusilla Grunow.

Note 219. Surirella angusta Kütz. = Surirella ovalis var. angusta (Kütz.) Van Heurck  In Texte the figure number is given as 12.  The Atlas uses fig. 13, which is correct.

Note 220. Surirella curvula Bréb. = Nitzschia lanceolata W.Sm. This synonymy is according to the writer, probably Grunow, of the caption for Plate 68, fig. 1.

Note 221. Surirella [sic] librile Ehrenb. = Cymatopleura solea (Bréb.) W.Sm.  The combination Surirella librile Ehrenb. is almost certainly an error. Ehrenberg (1838) described Navicula librile which is listed in Kützing 1849 as a synonym of Surirella solea Bréb., but there does not appear to be evidence that Ehrenberg made a transfer of the species to Surirella, as the name S. librile Ehrenb. implies.

Note 222. Surirella ovalis Bréb.  Fig. 4 is a monstrosity and was so indicated by Van Heurck.

Note 223. Surirella ovalis var. angusta (Kütz.) Van Heurck  In Texte the figure number is given as 12. The caption refers to fig. 13, which is correct.

Note 224. Surirella ovalis var. pinnata (W.Sm.) Van Heurck  In Texte given as fig. 13. Caption refers to fig. 12, which is correct.

Note 225. Surirella ovata Kütz. = Surirella ovalis var. ovata (Kütz.) Van Heurck   In Atlas these figures are referred-to as "Surirella ovata Kütz., varietes diverses"

Note 226. Surirella ovata var. aequalis Kütz.  For reasons unknown, Van Heurck let this variety of S. ovata stand while transferring all others (including the nominate) to S. ovalis.

Note 227. Surirella pinnata W.Sm. = Surirella ovalis var. pinnata (W.Sm.) Van Heurck  In Texte the illustration number is given as fig. 13. The caption refers to fig. 12, which is correct.

Note 228. Synedra acula Kütz. = Synedra acus var. acula (Kütz.) Grunow  Kützing's spelling (1844, 1865 printing. p.65) in both the text and register is acula and he retained that spelling in 1849. Not the same as Synedra acuta Ehrenb. which was also recognized by Kützing (1844 1865 printing) on p. 66.

Note 229. Synedra acus Kütz.  The author is given as (Kütz.) Grunow in Texte, based on Grunow 1862. In Atlas the author of the same figure is given as Kütz., Grun. l.c. The correct combination is, however, given in Kützing 1844 (1865 printing), p. 68.

Note 230. Synedra affinis var. ? lancettula Grunow   Caption numbering after fig. 25 restarts with 24. The present figure should be labeled fig. 28

Note 231. Synedra affinis var. ? rupicola Grunow Caption numbering after fig. 25 restarts with 24. The present figure should be labeled fig. 27.

Note 232. Synedra amphicephala var. ? [Grunow]  Caption has note "striis tenuioribus"

Note 233. Synedra deformis f. perminuta [?] = Synedra capitellata var. cymbelloides Grunow The author for this combination is not given, only the note "teste W.Arn." The author of the nominate variety (Synedra deformis var. deformis) is W.Sm.  Arnott's name is customarily given in the present work simply as Arn., so perhaps what Grunow intended to write was Synedra deformis W.Sm., f. perminuta, teste Arn. The combination S. deformis f. perminuta is, however, not listed in Van Landingham.

Note 234. Synedra demerarae Grunow   Caption numbering after fig. 25 restarts with 24. The present figure should be labeled fig. 29.

Note 235. Synedra fulgens (Kütz.) W.Sm.   Kutzing (1844, repr. 1865) refers to Exilaria fulgens Grev., and implies synonymy, in his description (1844/1865) of Licmophora fulgens. Therefore the correct name for the present taxon should be S. fulgens (Grev.) W.Sm. as is listed in VanLandingham (p. 3914).

Note 236. Synedra gaillonii (Bory) Ehrenb.  The specific epithet is misspelled gallionii in Texte.

Note 237. Synedra parva [?] = Synedra barbatula Kütz.  The author for S. parva is not given explicitly, only the note: "teste Arnott"). The species referred-to is probably Synedra parvaKütz.

Note 238. Synedra parvula Kütz. = Synedra vaucherii var. parvula (Kütz.) Rabenh.  In the Atlas the author given as (Kütz., partim?) Grunow. The author is not given in Texte.

Note 239. Synedra pulchella (Ralfs) Kütz.  Kützing 1844 (1865 printing) gives the basionym as Exilaria pulchella Ralfs, ex. specim.

Note 240. Synedra radians Kütz.  The author is given in both Texte and Atlas as (Kütz.) Grunow, but Kützing made this combination in 1844.

Note 241. Synedra rumpens Kütz. In the caption the name is given as Synedra rumpens Kütz., genuina !.

Note 242. Synedra tenella Grunow   Caption numbering after fig. 25 restarts with 24. The present figure should be labeled fig. 26.

Note 243. Synedra undulata (Bailey) W.Greg.  Van Landingham (p.3962) indicates author should be Bailey alone.

Note 244. Synedra vaucheriae var. parvula (Kütz.) Rabenh.  The author is given in error as (Kütz., partim?) Grunow in Atlas. The Texte does not indicate the author.

Note 245. Synedra vitrea (Bory) Kütz. = Synedra ulna var. vitrea (Bory) Van Heurck   The basionym appears to be Echinella vitrea Bory ex. Leormand. Herb. according to Kützing (1844, 1865 printing)

Note 246. Thalassiosira nordenskioldii Cleve  In errata (index vol. p 116), Van Heurck corrects the spelling in the caption from Thalasiosira to Thalassiosira.

Note 247. Trachysphenia australis var. ? auklandica Grunow  Note spelling "auklandica" rather than "aucklandica"

Note 248. Triceratium californicum Grunow  The illustration looks like a Lampriscus as understood by Round  et al. (1990).

Note 249. Triceratium laeve var. annulifera Grunow  The figure numbers in the caption are given as 11-11. Van Heurck (index vol. p. 116) corrects this to fig. 11-12, but there is no fig. 12 on the plate. My best guess is that he intended the correction as fig. 10-11, as I have shown.

Note 250. Triceratium sculptum Shadbolt   In Texte Van Heurck prefers Biddulphia to Triceratium.

Note 251. Triceratium shadboltianum Grev.  This specimen appears similar to Lampriscus as shown in Round et al. (1990). Note the spines on what might be suspected to be pseudocelli.

Note 252. Triceratium shadboltianum f. pentagona Grunow  The specimen illustrated appears like a Lampriscus as shown in Round et al. (1990).

Note 253. Triceratium sinense A.F.Schwarz = Actinoptychus annulatus Grunow   The words (genus novum?) are added.  Van Heurck (index vol., p. 117) corrects spelling of epithet from sinence to sinense and corrects the name of the author from Schwartz to Schwarz.

Note 254. Triceratium striolatum (Ehrenb.) Roper = Biddulphia rhombus var. trigona Cleve  The Atlas gives the author as Ehrenb.; VanLandingham (p. 4085) has entries for T. striolatum Ehrenb.(1839,1840) and T. striolatum sensu Roper 1854  non Ehrenb. (1839,1840).

Note 255. Vanheurckia rhomboides var. crassinervia (Bréb) Grunow   Varietal epithet is given in Texte as  crassinervis.

Note 256 Vanheurckia vulgaris (Thwaites) Van Heurck  Atlas gives Vanheurckia ? vulgare Thwaites
