Notes from Flann et al. 2010 Taxon 59: Type - Helenium quadridentatum Labill. (T. quadridentatus (Labill.) Less.) Notes: ING ascribes the generic name to Lessing (1832), considering (correctly) that Cassini (l.c.: 272) unequivocally accepts the taxon at subgeneric level. However, in the preceding generic synopsis (p. 264) he equally unequivocally places it on the same level as the other genera he enumerates. This is, therefore, a rare exception in which Cassini validly publishes alternative names of different rank (see also Pyrarda). ING furthermore treats Tetrodus as homotypic with Mesodetra Raf. 1817, but this again is inaccurate, because Mesodetra is typified by M. alata (Jacq.) Raf. (Rudbeckia alata Jacq. 1795), which is a later taxonomic synonym of, but not an illegitimate substitute for, Helenium quadridentatum Labill. 1792. The combination ‘T. quadridentatus’ was not published by Cassini. [Flann et al. 2010 Cassini Genera] [details]
