Cyperus pseudothyrsiflorus is a plant species native to Nuevo León, New Mexico and Texas,[3][4][5] It occurs in cultivated fields and other disturbed areas at elevations of less than 1000 m (3400 feet).[6]
Cyperus pseudothyrsiflorus is a perennial herb spreading by underground rhizomes. Stems are triangular in cross-section, up to 40 cm (16 inches) tall.[6]
It is a member of Cyperus, subgenus Cyperus,[citation needed] section Umbellati.[1] It was first formally described as a new variety of C. uniflorus by Georg Kükenthal in 1937,[7] but was promoted to an independent species in 1997.[1] It is very similar to C. uniflorus,[1][8] which is now known as C. retroflexus.[1]
