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." [1]
"Erect perennial from short rhizomes; culms 6-9 dm tall, nodes and internodes glabrous. Blades to 20 cm long, 1.5-4 mm wide, glabrous or villous on both surfaces, occasionally pilose basally above; sheaths glabrous, villous or sparsely papillose above, margins smooth; ligules 2-2.5 mm long. 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. Second glume and sterile lemmas 3-nerved, yellowish green , margins scarious, obtuse 2.2-3.2 mm long; fertile lemma and palea nerveless, papillose, obtuse, 2.2-3.2 mm long. Grain brownish, broadly ellipsoid, flat, 2 mm long." [1]
