Annual; caespitose. Culms erect, or geniculately ascending; 25-30 cm long. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 8-17 cm long; 3-5 mm wide. Leaf-blade surface scaberulous; glabrous, or pilose.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; not deciduous as a whole. Racemes 1; single; linear; smoothly terete; bilateral; 5-10 cm long; 5-8 mm wide; bearing 9-11 fertile spikelets on each. Rhachis fragile at the nodes. Spikelet packing broadside to rhachis. Rhachis internodes oblong; falling with spikelet above. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets absent, or rudimentary; 0-2 in number. Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6-8 mm long; falling entire; deciduous with accessory branch structures.
Sterile
Basal sterile spikelets absent, or rudimentary; 0-2 in number.
Fertile
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6-8 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume oblong; 5-6 mm long; 1 length of upper glume; coriaceous; without keels; 7-9 -veined. Lower glume lateral veins unequally thickened; ribbed. Lower glume apex with a unilateral tooth; truncate. Upper glume oblong; 5-6 mm long; 0.8-0.9 length of adjacent fertile lemma; coriaceous; without keels; 7-9 -veined. Upper glume lateral veins unequally thickened; ribbed; parallel at apex. Upper glume apex with a unilateral tooth; truncate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong, or ovate; 6-7 mm long; coriaceous; without keel; 5 -veined. Lemma apex entire; truncate; awned, or awned only on distal spikelets; 1 -awned. Principal lemma awn subterete below; 30-40 mm long overall (lower spikelets 0-18). Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2. Ovary pubescent on apex.
