The individual genera are diagnosed by a combination of several characters (Table 2), the most notable being the presence of a gynophore and ligule in Ficinia (including Desmoschoenus), presence of two or three scales in the lower florets in Hellmuthia, and perennial growth form and spiral glume arrangement in Scirpoides, whereas Isolepis includes predominantly annual species with a spiral glume arrangement.

Other important structures used for identification purposes, such as the ligule (Figures 4 and 5), collar (Figures 6 and 7), and auricles (Figures 8 and 9), are found at the collar area where the leaf sheath and blade join (Figures 10 to 13).
