HABIT Perennial. Culms erect; 50–150 cm long. Ligule a fringe of hairs. Leaf-blades coriaceous; stiff. Leaf-blade apex pungent.
INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets linear; subterete; 16–24 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; pubescent; pungent.
GLUMES Glumes persistent; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 1.1–1.3 length of upper glume; scarious; without keels; 9–11 -veined. Lower glume surface without pits. Lower glume apex acuminate. Upper glume lanceolate; 1.5–1.75 length of adjacent fertile lemma; scarious; without keels; 3–5 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma lanceolate; laterally compressed; coriaceous; without keel; wingless; 3 -veined. Lemma surface unwrinkled; without grooves. Lemma margins convolute; covering most of palea; ciliate. Lemma apex lobed; 2 -fid; incised 0.1 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; flexuous. Palea 1 length of lemma; 2 -veined. Palea keels approximate.
FLOWER Lodicules 2. Anthers 3. Stigmas 2.
