Plants annual. Culms up to 100 cm long, decumbent. Ligule an eciliate membrane. Blades 5-30 cm by 2-10 mm. Inflorescence composed of racemes.
Racemes 4-12, digitate, unilateral, 4-12 cm long. Rachis narrowly winged, angular, glabrous on surface, scabrous on margins. Spikelets in pairs: fertile spikelets
pedicelled, 2 in the cluster. Pedicels unequal. Fertile spikelets comprising 1 basal sterile florets, 1 fertile florets, without rhachilla extension; lanceolate, 2-3 mm long,

surface pubescent, apex acute. Florets: basal sterile florets barren, without significant palea. Lemma elliptic, as long as spikelet, membraneous, 7-nerved, pubescent and
setose, eciliate on margins, acute. Fertile lemma 2-3 mm long, elliptic, cartilaginous, much thinner on margins, without keel; margins flat, apex acute. Palea cartilaginous.
