HABIT Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; woody. Culm-internodes terete. Lateral branches dendroid. Ligule an eciliate membrane.

INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in globose clusters; 0.5–1 cm long; dense; pubescent on internodes; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.

Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 2–4 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 12–17 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.

GLUMES Glumes two; persistent; similar; shorter than spikelet. Lower glume ovate; 6–8 mm long; coriaceous; without keels. Lower glume surface pubescent. Lower glume apex acute. Upper glume ovate; 6–8 mm long; chartaceous; without keels. Upper glume primary vein thickened. Upper glume surface pubescent. Upper glume apex acute.

FLORETS Fertile lemma ovate; 8–12 mm long; chartaceous; without keel; 16–20 -veined. Lemma surface pubescent. Lemma apex acute; mucronate. Palea chartaceous; 2-keeled but the uppermost without keels. Palea keels ciliolate.
