Lower glume apex truncate. Upper glume oblong; 0.5 length of spikelet; membranous; without keels; 3-5 -veined. Upper glume surface glabrous, or pilose; with capitate hairs. Upper glume hairs white. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 1 length of spikelet; membranous; 7 -veined; glabrous, or pubescent; with capitate hairs; bearing white hairs; acute.
