• Comment: Clarke cites "Var. β. cyrtostachys" under Cyperus eragrostis and lists "C. cyrtostachys (sp.), Miq. Fl. Ind. Bat. iii. p. 257." [i.e. F.A.W.Miquel, Fl. Ned. Ind. 3(2): 257 (1856)] in synonymy. However, since Miquel published the name at varietal rank Clarke's publication is here treated as a secondary reference.
