Cyperus pseudovegetus has been called “Cyperus vegetus Willd.” (M. L. Fernald 1950). The var. megalanthus Kükenthal of eastern Mexico and Central America recognized by M. F. Denton (1978b) is now considered a distinct species, C. megalanthus (Kükenthal) G. C. Tucker (see G. C. Tucker 1994).
Cyperus pseudovegetus is introduced in Massachusetts.
