HABIT Perennial. Culms 80–120 cm long. Ligule a ciliolate membrane. Leaf-blade base with a false petiole. Leaf-blades elliptic. Leaf-blade venation with distinct cross veins.
INFLORESCENCE Inflorescence composed of racemes.
Racemes borne along a central axis; unilateral. Rhachis angular.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 5–5.5 mm long; falling entire. Spikelet callus pubescent. Rhachilla internodes elongated between glumes.
GLUMES Glumes shorter than spikelet. Lower glume lanceolate; 0.8–0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acute. Upper glume lanceolate; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume apex acute; mucronate.
FLORETS Fertile lemma oblong; membranous; without keel; wingless; 3–5 -veined. Lemma midvein scaberulous. Lemma lateral veins obscure. Lemma surface unwrinkled; without grooves. Lemma apex acute; awned; 1 -awned. Principal lemma awn curved. Apical sterile florets 1 in number; barren; oblong. Apical sterile lemmas awned.
