|Sphenophora F.T. Kützing 1833, pg. 39 (567)|
|Comments||SVL says Sphenophora Ehrenberg 1838 (pub. 000288) p. 216 (subgenus of Gomphonema Agardh). This information is in part erroneous, the name Spenophora appears indeed p. 216 in the German discussion on Gomphonema where it is accredited to Kutzing 1833 and given as a subgenus of Gomphonema. Kutzing 1833 (000594) p. 39 (567) introduced this name as a subgroup within Gomphonema (Kutzing divided Gomphonema Ag. into 3 subgroups a) Cymbophora, b) Paltonophora, c) Sphenophora). Sphenophora is qualified by Kutzing as Gomphonemata genuina (true Gomphonema). Several species are described for the group Sphenophora but no type is given.|
