| Comments | Type by monotypy. Type by monotypy. Comments: Described as new in Ehrenberg 1840, p. 161 (ref. 000292) with one species included, P. nummuloides (Mont.) Ehr. It is also described as new in Ehrenberg 1840, p. 48 (ref. 000290); in this paper, one species is included, P. nummuloides (p. 78), for which Ehrenberg gives as synonyms Trochiscia moniliformis Montagne 1837 and Melosira hormoides Montagne msc. 1838. Podosira is also introduced as a new genus in Ehrenberg 1843, p. 402 (ref. 000294), and illustrated pl. I/III, fig. 34 (Podosira moniliformis). See also Ehrenberg 1841 (ref. 0953) p. 128 (ref. 0290 and 000953 are identical except for pagination). It is unclear which one of these two 1840 Ehrenberg's publications (ref. 000292 and 000290) was published first. Farr et al. (1979) give as original reference Ehrenberg 1840, p. 161 (ref. 000292). |
