• Comment: Clarke indirectly refers to the intended basionym, Elynanthus octandrus Nees, via his citation of "B. VII. 377 sub Elynanthus Nees" [i.e. G.Bentham, Fl. Austral. 7: 377 (1878)]. However, as the genus Tetrariopsis had not been validly published the species name is also invalid (ICN Art. 35.1 (Melbourne Code, 2012)).
