Lateral branches dendroid. Branch complement one to three; in a clump; subtended by a bare patch above the node; with subequal branches. Leaves distichous. Leaf-sheaths 1 cm long; glabrous on surface; outer margin hairy. Leaf-sheath oral hairs setose; 5-15 mm long. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 1.5-3 cm long; 4-6 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade surface glabrous. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes; terminal and axillary. Racemes 1; single; straight; bilateral; 10-20 cm long; bearing 8-15 fertile spikelets on each. Rhachis glabrous on surface. Spikelet packing distant. Spikelets deflexed; clustered at each node. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 2 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 15 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 2 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 15 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume ovate; chartaceous; without keels. Lower glume apex acute. Upper glume lanceolate. Upper glume apex acute.
    Florets
    Basal sterile florets barren; persisting on inflorescence. Lemma of lower sterile floret similar to fertile lemma. Fertile lemma lanceolate, or ovate; 10 mm long; chartaceous; without keel; 3-5 -veined. Lemma margins ciliolate; hairy above. Lemma apex obtuse; mucronate. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
