Sessile spikelet 2.5–4 mm long, lanceolate; inferior glume firmly membranous, slightly concave on the back and pilose in the lower half; superior glume minutely hispid along the keel, acute at the apex; inferior floret empty, the lemma c. 3 mm long, oblong-linear, ciliolate at the apex; superior floret bisexual, epaleate, the lemma c. 1.5 mm long, stipitiform, glabrous, awned; awn c. 25 mm long, geniculate; anthers c. 1.5 mm long. Pedicelled spikelet neuter; inferior glume c. 3.5 mm long, oblong, with sparse long white hairs along the lateral keels and ciliolate towards the apex; superior glume c. 3 mm long, lanceolate, delicate, ciliate on the margins; inferior lemma c. 2 mm long, oblong, obtuse at the apex. |
