Culm to 60 cm, long and short hairs below inflorescence otherwise glabrous. Inflorescence to 10 cm, spikelets few; rachis, branches and pedicels abundantly long hairy especially at branch axils. Spikelets of up to 7 golden florets. Glumes becoming acute or mucronate, glabrous, > adjacent lemma lobes; lower to 11 mm, 3-nerved, upper to 13 mm, 5-nerved.

In a specimen from cultivation some scattered, weak, long (3 mm) hairs, like those of the sheath, were present on the abaxial leaf-blade though this was never seen in plants from the wild.
