Synonymy: Not Applicable

Common name: Cupgrasses.

Description:
Annual or perennial; leaf blade flat; ligule of hairs.

Inflorescence a panicle of racemes; spikelets 1-flowered, acute, dorsally compressed, erect, adaxial (i.e. with the first glume towards the axis), supported on a hardened disk-like callus which is articulated on the short pedicel, arranged in 1 or 2 rows along one side of the slender racemes; first glume vestigial; second glume and sterile lemma faintly 5-nerved, the lemma rather shorter than the glume, the sterile lemma shorter, coriaceous, ovate, mucronate; the palea also hardened, similar but not mucronate. (The callus is thought to represent a rudimentary glume in which case what is called here the second glume is actually a sterile lemma).

Distribution:  About 20 species from warm areas.
