HABIT Perennial. Culms 10–70 cm long. Ligule an eciliate membrane. Leaf-blades filiform.
INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 4.5–6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded.
GLUMES Glumes persistent; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous; without pits. Lower glume apex acuminate; awned. Upper glume lanceolate; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume surface asperulous. Upper glume apex acuminate; awned; 1 -awned.
FLORETS Fertile lemma elliptic; coriaceous; without keel; wingless; 5 -veined. Lemma surface asperulous; unwrinkled; without grooves. Lemma margins convolute; covering most of palea. Lemma apex truncate; awned; 5 -awned. Principal lemma awn dorsal; geniculate. Lateral lemma awns shorter than principal. Palea 0.75 length of lemma.
