Leaf blade linear-lanceolate to lanceolate, 5–12 × 0.8–1.7 cm, abaxially densely pubescent, adaxially glabrous. Pseudospikelets several, clustered at each node, linear-lanceolate to lanceolate, 1.5–2 cm; prophylls ovate, 3–3.5 mm, 2-keeled; gemmiferous bracts 2 or 3, ovate-elliptic to ovate-oblong, 3–3.5 mm, apex obtuse to acute, very shortly mucronate; florets 6 or 7, middle 3 or 4 perfect; rachilla segments flat, 2–3 mm, apex inflated and cupular. Glumes absent; lemma ovate-oblong, 7.5–8 mm, glabrous, 9–11-veined, apex acute, mucronate; palea linear-lanceolate, slightly longer than lemma, 4-veined between and 2-veined on either side of keels, apex with a cluster of white hairs; lodicules 3, unequal; anterior oblique, ca. 2 mm, margins long ciliate; posterior subobovate, ca. 1.2 mm.
