Leaves mostly basal. Leaf-sheaths as wide as blade at the collar; smooth; glabrous on surface. Ligule a ciliate membrane; 0.5-1 mm long. Leaf-blades convolute; 10-50 cm long; 2-6 mm wide; coriaceous; stiff; glaucous. Leaf-blade surface ribbed. Leaf-blade margins scabrous. Leaf-blade apex attenuate; filiform.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes numerous; borne along a central axis; closely spaced; in a multilateral false spike; spreading; oblong; unilateral; 1-2 cm long. Central inflorescence axis 15-40 cm long. Rhachis semiterete; puberulous on surface. Spikelet packing broadside to rhachis; crowded. Spikelets spreading; solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-18 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed strongly; 2.5-13 mm long; falling entire. Rhachilla internodes eventually visible between lemmas.
Fertile
Spikelets comprising 2-18 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed strongly; 2.5-13 mm long; falling entire. Rhachilla internodes eventually visible between lemmas.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume ovate; 0.7-1.5 mm long; 0.5 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 1.1-2 mm long; 0.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile florets free at tip. Fertile lemma ovate; laterally compressed; 1.5-1.8 mm long; membranous; keeled; 3 -veined. Lemma midvein scaberulous. Lemma lateral veins obscure; close to margins. Lemma apex acute. Palea oblong; 1 length of lemma; 2 -veined. Palea keels scaberulous. Palea apex entire; acute. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; cuneate; fleshy; entire; emarginate. Anthers 3; linear. Stigmas 2; laterally exserted.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ovoid; trigonous; without sulcus. Embryo 0.3-0.4 length of caryopsis. Hilum punctiform. Disseminule comprising a spikelet.
