Conservation

LC - least concern

Morphology General Habit

Annual; caespitose. Culms erect; 71-90 cm long. Culm-internodes distally pilose. Leaf-sheaths pilose. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 1 mm long. Leaf-blades 20-45 cm long; 2-5 mm wide. Leaf-blade surface smooth, or scaberulous; pilose; hairy on both sides.

Morphology Reproductive morphology Inflorescences

Inflorescence composed of racemes. Peduncle pubescent above. Racemes 1; single; bilateral; (3.5-)5-6.5 cm long; 10-15 mm wide. Rhachis fragile at the nodes; flattened; ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 1.5-1.75 mm long; falling with spikelet above. Spikelets solitary. Fertile spikelets sessile.

Morphology Reproductive morphology Inflorescences Spikelets

Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10-12 mm long; falling entire; deciduous with accessory branch structures.

Fertile

Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 10-12 mm long; falling entire; deciduous with accessory branch structures.

Morphology Reproductive morphology Inflorescences Bracts Glume

Glumes similar; shorter than spikelet. Lower glume oblong; asymmetrical; 7-10 mm long; 1 length of upper glume; coriaceous; 2-keeled; keeled all along; winged on keel (1 keel); winged near apex, or above; 5-9 -veined. Lower glume surface pubescent. Lower glume apex with a unilateral tooth. Upper glume oblong; asymmetrical; 7-10 mm long; 0.9-1 length of adjacent fertile lemma; coriaceous; 2-keeled; keeled all along; winged on keel (1 keel); winged near apex, or above; 5-9 -veined. Upper glume lateral veins divergent at apex. Upper glume surface pubescent. Upper glume apex with a unilateral tooth.

Morphology Reproductive morphology Flowers Florets

Fertile lemma elliptic; 10-12 mm long; coriaceous; without keel; 9-11 -veined. Lemma surface pubescent. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn 50-60(-90) mm long overall. Palea 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped; 1 in number.
