Inflorescences digitate; branches 1–4, 1–3 cm long, 4–11 mm wide including the spikelets. Spikelets overlapping, (3–) 4–7 mm long, with 5–7 bisexual florets. Glumes unequal in length; lower glume 1.9–3 mm long; upper glume 2.5–4 mm long, obtuse. Basal lemma 3–4.5 mm long, muticous; keel wingless; midnerve smooth or scaberulous. Palea keels wingless. Grain enclosed by the lemma and palea, elliptic or circular, trigonous in T.S., deeply concave on hilar side.
Tufted perennial 70-180 mm high; culm slender. Leaf blade 50-180 x 3-5 mm; ligule a fringed membrane. Inflorescence digitate; racemes 1-4, 10-25 x 4-11 mm, stout. Spikelet 4-7 mm long; 2 to 3-flowered, disarticulating above the glumes and between the florets at maturity; lower glume oblong-lanceolate, 1-nerved, apex subacute; upper glume 3-4 mm long, acute to subacute; lemma 4-5 mm long, narrowly oblong-lanceolate, apex obtuse or subacute, keel scabrid; palea keels scabrid; anther 0.5-0.8 mm long; caryopsis broadly trigonous, surface coarsely striate.
