Plants annual. Culms up to 90 cm long. Blades 2.5-18 cm by 3-8 mm. Racemes 3-14, longest 4-16 cm long, common axis up to 5 cm long. Rachis usually without
setae. Spikelets usually homomorphous, lanceolate, 2.75-4 mm long. Glumes dissimilar. Lower glume absent, or rarely up to 0.2 mm long. Upper glume 0.3-1 mm
long, 0.15-0.3 times as long as the spikelet. Sterile lemma with at most a few hairs between the bristles in the second interspace, 7-nerved, inequidistant, those of the
sessile spikelets sometimes subglabrous and more or less equidistantly nerved, spikelets then heteromorphous. Fertile floret yellowish, occasionally purplish in fruit.
Anthers 0.9-1 mm long, purple, connective zone yellow. Stigma purple. Notes

Plants annual, tufted or loosely tufted. Culms 30-110 cm long, geniculate at base, or creeping, rarely rooting at the lower nodes, branched mainly at base. Sheaths
glabrous. Ligule 1-3 mm long, truncate, erose, membraneous. Blades 20-60 cm by 8- 10 mm, ascending, soft, glabrous. Inflorescence composed of racemes. Racemes 2-
10, digitate, unilateral, 4-20 cm long. Rachis broadly winged, with sharp-edged midrib. Spikelets in threes: fertile spikelets pedicelled, 3 in the cluster. Pedicels
unequal, ciliate, hairy at the tip, with up to 1 mm long hairs. Fertile spikelets comprising 1 basal sterile florets, 1 fertile florets, without rhachilla extension; elliptic,
1.7-2.6 mm long, with hairs extending 0.4-0.9 mm beyond apex, falling entire. Glumes dissimilar. Lower glume absent, or obscure. Upper glume elliptic, 0.8 times
length of spikelet, membraneous, 3-nerved; surface pubescent, with clavate hairs, apex acute. Florets: basal sterile florets barren, without significant palea; lemma elliptic, as
long as spikelet, membraneous, 5-7-nerved, inequidistant, pubescent, or pilose, hairy between nerves, with clavate hairs, bearing hairs 0.3-0.9 mm long, acute. Fertile
lemma elliptic, 1.7-2.8 mm long, cartilaginous, without keel; margins flat, apex acute. Palea cartilaginous. Anthers 0.4-0.8 mm long, dark purple. Caryopsis flattened.
