Ligule a short-ciliate rim; auricles densely barbate; collar glabrous. Leaf-laminae 6-20 cm, c. 1 mm when expanded, convolute, setaceous, scaberulous or hirtellous above, with a few long hairs near to the base, scaberulous beneath. Panicle 30 x 20 cm, lax and much branched, sometimes with more or less spreading branches, or contracted with short branches; axis terete in the lower part, angular and scaberulous upwards. Spikelets pallid or purplish-brown. Glumes nearly equal or somewhat unequal, acute or subacute, hirtellous or ciliate at least on the back, 3-nerved; the inferior 6-11 mm long, rounded or slightly keeled, abruptly contracted or truncate and erose, with a short mucro; the superior 10-13 mm long, subobtuse or subacute, slightly 2-fid or emarginate, with a short awn from the sinus. Lemma c. 3.5-4 mm long (including the callus), conspicuously asperulous-tuberculate, especially towards the apex, tapering gradually into a column; callus 0.5-0.75 mm long, curved, with an oblique, glabrous, long and acute point, having a ring of short hairs near the point and a ring of long hairs at the base of the lemma; column 7-10 mm long, hairy towards the apex or twisted; central awn 5-7 cm long, plumose all over or naked in the lower part and plumose towards the apex, with a naked excurrent apex; lateral awns up to 2.5 cm long, very delicate, naked.
