Filicites (Sphenopteris)
Discussion
The name Sphenopteris was first validly published by Brongniart (1822: 233) for a section of the fossil-genus Filicites Schloth. ex Brongn. (Brongniart, 1822). The taxon was shortly afterwards raised in rank to genus by Sternberg (1825) but who illegitimately altered the spelling to Sphaenopteris. Brongniart (1828a,b) accepted the change in rank but reverted to the original spelling, Sphenopteris (see also Sternberg, 1833), and this is how the name is normally used today.
Taxonomy
Filicites (Sphenopteris) was named by Brongniart (1822) [It should be considered a section of Filicites, and not as a subgenus.]. It is considered to be a form taxon.
It was reranked as Sphenopteris by Knowlton (1919), Lakhanpal et al. (1976), Lapasha and Miller (1985), Chandra and Tewari (1991), McLoughlin et al. (1995), Dilcher et al. (2005), Cleal and Thomas (2023).
It was assigned to Filicites by Brongniart (1822); to Pteridophyta by Knowlton (1919); to Filicales by Lakhanpal et al. (1976), Lapasha and Miller (1985), Chandra and Tewari (1991), McLoughlin et al. (1995); to Sphenopteridae by Dilcher et al. (2005); and to Lyginopteridales by Cleal and Thomas (2023).
