| Description: |
Caespitose perennial; culms up to 130 cm high, mostly erect; leaf laminas 4–15 cm × 5–8 mm, glaucous, tuberculately pilose near the base, prominently nerved, tapering to an acute point. Inflorescence terminal, of single racemes each 5–7 cm long and fragile even when young; rhachis internodes and pedicels densely villous, the hairs pinkish or sometimes golden, the internodes and pedicels themselves yellowish to purple, subequal, subinflated. Sessile spikelet c. 8 mm long, lanceolate (not including the wings of the inferior glume); inferior glume coriaceous, 2-keeled along its length, flat or convex between the keels, densely villous on the back in the inferior 2/3, pilose towards the margins above, winged on the keels, the wings broadening above into lobes up to 1 mm wide, these, together with the emarginate apex of the glume, giving the glume the appearance of being broadly 3-lobed, the central lobe slightly the longest but exceeded by the superior glume; superior lemma with a geniculate awn c. 30 mm long. Pedicelled spikelet 3–4 mm long, barren, much reduced and represented only by its glumes, these similar to those of the sessile spikelet but the inferior longer than the superior. |
