HABIT Perennial; caespitose; clumped loosely. Rhizomes absent, or short. Culms erect; 30–60 cm long. Ligule an eciliate membrane. Leaf-blades convolute; 1–2.5 mm wide; coriaceous; stiff. Leaf-blade surface ribbed; smooth.
INFLORESCENCE Inflorescence a panicle.
Panicle open; oblong, or ovate; loose, or effuse; 10–20 cm long. Primary panicle branches 3–6 cm long. Panicle branches smooth.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 2(–3) fertile florets; with a barren rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 4.2–6.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; exceeding apex of florets; similar to fertile lemma in texture; shiny. Lower glume lanceolate; 4.2–6.5 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 4.2–6.5 mm long; 1.3 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.
FLORETS Fertile lemma oblong; 3.2–4 mm long; membranous; shiny; without keel; 5 -veined. Lemma apex erose, or dentate; 4 -fid; awned; 1 -awned. Principal lemma awn dorsal; arising 0.25 way up back of lemma; straight; 2.5–3 mm long overall; not or scarcely exserted from spikelet.
FLOWER Anthers 3; 1.7–2.3 mm long. Ovary glabrous.
FRUIT Caryopsis with adherent pericarp. Hilum punctiform.
