HABIT Perennial. Culms erect; 60–70 cm long. Ligule a fringe of hairs.

INFLORESCENCE Inflorescence composed of racemes.

Racemes borne along a central axis; unilateral. Rhachis angular. Spikelet packing lax.

Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels linear.

FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite. Floret callus evident; pubescent.

GLUMES Glumes persistent; shorter than spikelet. Lower glume lanceolate; 0.8–1 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 elliptic; 1.2 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume apex acute.

FLORETS Fertile lemma lanceolate; membranous; keeled; wingless; 3 -veined. Lemma midvein ciliate. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus. Apical sterile florets 1 in number; barren; lanceolate. Apical sterile lemmas awned.
