Glumes occasionally purple-margined, lanceolate, subobtuse, ± equal, 8-13.5-(17.5) mm long, lower (5)-7-9-(ll)- nerved, upper 5-7-(9)-nerved, sometimes with scattered long hairs. Lemma 2.5-3.5-(4.5) mm long, 9- nerved, upper row of hairs ± = or slightly > lemma, in marginal tufts only, or with two additional central tufts, lower row with short weak central tufts, or continuous, with longer marginal tufts barely, or not, reaching upper marginal tufts, elsewhere glabrous, shining; lemma lobes 6-13 mm long, gradually narrowed to long awns.
