Perennial; caespitose. Culms 60-80 cm long. Leaf-sheaths hirsute. Ligule an eciliate membrane. Leaf-blades flexuous; flat, or involute; 30-40 cm long; 1-2 mm wide. Leaf-blade surface scabrous; rough adaxially.
Inflorescence composed of racemes. Racemes 2-3; paired, or digitate; unilateral; 30 cm long. Central inflorescence axis 3-6 cm long. Rhachis angular. Spikelet packing lax; irregular. Spikelets in pairs, or in threes, or clustered at each node. Fertile spikelets pedicelled; 2-4 in the cluster. Pedicels angular.
Glumes one the lower absent or obscure; shorter than spikelet; thinner than fertile lemma. Upper glume elliptic; 0.5 length of spikelet; membranous; without keels; 3 -veined. Upper glume surface glabrous. Upper glume apex truncate, or obtuse.
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 0.9 length of spikelet; membranous; 5 -veined; glabrous; acute.
