HABIT Perennial. Culms erect; 20–60 cm long. Ligule an eciliate membrane. Leaf-blades coriaceous.
INFLORESCENCE Inflorescence composed of racemes.
Racemes single; bilateral. Rhachis fragile at the nodes; semiterete. Spikelet packing broadside to rhachis; lax.
Spikelets appressed; solitary. Fertile spikelets sessile.
FERTILE SPIKELETS Spikelets comprising 3–6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4.5–7 mm long; falling entire; deciduous with accessory branch structures. Rhachilla internodes definite.
GLUMES Glumes collateral; shorter than spikelet; firmer than fertile lemma. Lower glume oblong; 1 length of upper glume; coriaceous; without keels; 5 -veined. Lower glume lateral veins ribbed. Lower glume surface without pits. Lower glume apex obtuse. Upper glume oblong; 1–1.4 length of adjacent fertile lemma; coriaceous; without keels; 5 -veined. Upper glume lateral veins ribbed. Upper glume apex obtuse.
FLORETS Fertile lemma elliptic; membranous; without keel; wingless; 5 -veined. Lemma surface unwrinkled; without grooves. Lemma apex obtuse. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Anthers 3. Ovary glabrous.
FRUIT Caryopsis with adherent pericarp; oblong; dorsally compressed. Hilum elliptic.
