Panicle narrow, 4-9 cm long, dense to ± loose; branches usually paired, ascending, flexuous, scabrid. Spikelets 3-4-flowered, broadly wedge-shaped, 4-6.5mm long, tinged with purple; glumes unequal, 3-nerved, the lower oblong to elliptic, 3-3.8mm long, the upper broader, 3.2-4.5 mm long; lemmas oblong or elliptic in side-view, (2.8-)3-4.5 mm long, obtuse or subacute, ciliate on the keel and marginal nerves, with very sparse wool at the base; plea shorter than the lemma, scabrid along the keels; anthers 1.5-2mm long.
