Leaf blade linear-lanceolate, 7–17 × 1.2–1.6 cm, both surfaces glabrous or abaxially proximally pilose. Pseudospikelets solitary or several clustered at each node of flowering branch, linear to linear-lanceolate, slightly compressed, to 4 cm, prophylls obtuse, keels ciliolate; gemmiferous bracts 3–5, narrowly triangular or subovate, glabrous, obtuse; fertile florets 6–12; rachilla internodes 2–4 mm. Glumes usually absent; lemma ovate-oblong, 5–9.5 mm, many veined, apex obtusely acute or acute with fine tip; palea usually slightly longer than lemma, keels ciliolate, 3–5-veined between keels; lodicules 3, unequal, obovate, ca. 1.4 mm, obtuse, margins ciliate. Filaments distinct; anther obtuse at apex. Ovary narrow, apex thickened and hispidulous; style slender, hispidulous; stigmas 3. New shoots May–Jun, fl. Aug–Dec.
