Description
"Annuals or perennials. Leaves primarily basal and low cauline; blade margins usually scaberulous; ligules membranous. Spikelets plano-convex, terminal floret fertile, basal floret sterile. Frist glume usually absent, sterile lemma resembles 2nd glume; fertile lemma and paleas indurate, lustrous, yellowish or brownish. These plants are all important forage grasses." </ref name="Radford et al 1964">Radford, Albert E., Harry E. Ahles, and C. Ritchie Bell. Manual of the Vascular Flora of the Carolinas. 1964, 1968.

Racemes 3-5, racemose, ascending, 2-6 cm long; rachis wing scaberulous, 1-1.2 mm wide. Spikelets broadly obovoid to suborbicular, flattish, 2.2-3.2 mm long, in 4 rows, 2 rows rudimentary; pedicels scaberulous angled, 0.1-1 mm long.
