Morphology General Habit
Annual; caespitose. Culms erect; 30-60 cm long; 3-6 -noded. Culm-internodes terete; striate; smooth. Culm-nodes constricted; glabrous. Leaf-sheaths 6-12 cm long; woolly; with tubercle-based hairs. Ligule a ciliolate membrane; 0.5 mm long; erose. Leaf-blades 10-20 cm long; 3-6 mm wide. Leaf-blade surface woolly. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 3-4; digitate; unilateral; 5-10 cm long. Central inflorescence axis 0.5-4 cm long; glabrous, or pubescent. Rhachis angular; 0.5 mm wide; scaberulous on margins. Spikelets in threes. Fertile spikelets pedicelled; 3 in the cluster. Pedicels unequal; 1-3 mm long; tip cupuliform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.8-2.4 mm long; with hairs extending 1 mm beyond apex; falling entire.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.8-2.4 mm long; with hairs extending 1 mm beyond apex; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes one the lower absent or obscure; shorter than spikelet; thinner than fertile lemma. Upper glume elliptic; 1.6-2.2 mm long; 0.9 length of spikelet; membranous; without keels; 3 -veined. Upper glume surface pubescent; with capitate hairs. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; with palea. Lemma of lower sterile floret elliptic; 1.8-2.2 mm long; 1 length of spikelet; membranous; (5-)7 -veined; prominently veined; pubescent; hairy between veins; with capitate hairs. Palea of lower sterile floret hyaline; 0.3 mm long. Fertile lemma elliptic; 1.6-2.2 mm long; cartilaginous; much thinner on margins; dark brown; without keel. Lemma surface striate. Lemma margins flat; covering most of palea. Lemma apex acute. Palea cartilaginous.
