HABIT Perennial. Rhizomes short. Culms 40–70 cm long. Ligule a ciliolate membrane. Leaf-blade midrib evident.
INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 12–15 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pilose.
GLUMES Glumes lower persistent, upper deciduous; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 0.66 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume lateral veins ribbed. Lower glume surface without pits. Lower glume apex acute. Upper glume lanceolate; 0.5 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume lateral veins ribbed. Upper glume apex acute.
FLORETS Fertile lemma lanceolate; coriaceous; without keel; wingless; 3 -veined. Lemma surface asperulous; unwrinkled; without grooves. Lemma apex dentate; 2 -fid; incised 0.2 of lemma length; setaceously attenuate; awned; 1 -awned. Principal lemma awn from a sinus. Apical sterile florets 1 in number; barren; linear. Apical sterile lemmas awned.
