Base woolly; mostly erect, leafy, most 15-30 cm high; lower nodes of the culms pubescent, the upper ones more or less glabrous; leaves stiff, lanceolate, flat or involute, striate, lower surface pubescent and with tubercle-seated hairs, 1.3-6 cm long, 1.4-4 mm broad, sheaths mostly shorter than the internodes.
Racemes narrowly oblong, 20-35 mm long, 5-8 mm broad (excluding the bristles), the stem glabrous or only slightly pubescent beneath the inflorescence; spikelets bearded at the base, 4-5 mm long (excluding the bristles), 1.25-1.5 mm broad, setose but otherwise mostly glabrous or the upper spikelets pubescent, with bristles the longer of which are 1.2-3 mm long; glumes with nerves in the upper part narrower than the space between them, first glume 3.5-4.5 mm long, rigid, 3-5-nerved, acuminate, with a hyaline cavity in the lower half, scaberulous-ciliate on the margins in the upper part and nerves but elsewhere glabrous, the second glume of equal length, scaberulous; first lemma 3-nerved, rough to pubescent, sterile, 2.7-3.2 mm long; second (fertile) lemma 2.7-3.5 mm long, scarious, multistriate, palea similar.

Biology:
Although separated principally on minute characters, Blake recorded that its relatively glabrous spikelets, smaller leaves and habit allow its recognition when growing with T. mitchelliana.
