| Comments | Gomphonema Agardh 1824 is rejected vs Gomphonema Ehrenberg 1832 (nom. cons.) (see ICBN 1956, p. 200, ref. 006916). No type is listed in ICBN 1956 (ref. 006916), G. geminatum is given as type in ICBN 1961 (ref. 006910), p. 208. In original publication, Latin description of the genus p. XVI and Latin descriptions of 2 species G. paradoxum (p. 11) and G. geminatum (p. 12), no type designated. Farr et al. 1979 indicate that the type (G. geminatum) was designated by Kutzing 1844 (ref. 000595), p. 86, 122. Kützing transferred Echinella paradoxa (on which G. paradoxum is based) to genus Rhipidophora (p. 122), retaining Gomphonema geminatum within genus Gomphonema (p. 86). Kützing's action by itself does not constitute lectotypification of the genus. Pre-conservation lectotypification with G. geminatum is effected by Boyer 1927, p. 187 (ref. 000155). Nomenclatural synonym: Didymosphenia M. Schmidt 1899 (nom. cons.). |
