Plants cespitose, with caudices or knotty crowns. Basal rosettes well-differentiated. Culms 18-100 cm, decumbent to erect, usually glabrous; nodes bearded or glabrous; fall phase often much branched and rebranched, with smaller blades and panicles than those of the culms. Cauline leaves 3-7; sheaths usually glabrous, lower sheaths sometimes pilose; ligules 0.2-0.8 mm, of hairs, or absent. Primary panicles exserted. Spikelets ellipsoid to obovoid, glabrous or pubescent. Upper florets acute to obtuse.

Discussion

Gene exchange between the subspecies of Dichanthelium dichotomum, and between D. dichotomum and other species in the genus, appears to be rather common.
