* Inflorescence a terminal pair of racemes and 1-2 axillary pairs.Spatheole linear, 4-10 cm long. Racemes in paires, 2-3 cm long, with 4-6 spikelet pairs each; rhachis fragile, with white hairs of 0.5-2 mm long on the nodes and margins; bases filiform, the longest 4.5-8 mm long, almost glabrous. Pedicels and internodes linear, 4 mm long. Lower raceme with 1-2 pairs of homogamous spikelets; lower raceme without homogamous spikelets.
* Sessile spikelets lanceolate, 4.5-6.5 mm long, light green; callus cuneate, 1.5 mm long, pubescent. Lower glume coriaceous, grey,with a slight median depression and keel-less, glabrous or pubescent. Upper lemma linear, membranous, with a geniculate awn of 8-15 mm long from the sinus, column hirsute with brown hairs of 0.3-0.4 mm long.
