Information
Robust perennial, forming coarse tufts from a short rhizome; culms 2–4 m. high, up to 8 mm. in diameter, often supported by stilt roots. Leaf-blades up to 60 cm. long, 2 cm. wide. False panicle large, dense, 30–60 cm. long; spatheoles narrowly lanceolate, 2.2–3.2 cm. long, russet-brown, the peduncles up to 1/2 as long(7–15 mm.); racemes 1.2–1.6 cm. long, 6–8-awned per pair (this being the maximum number in a given panicle), at length deflexed; raceme-bases subequal, the upper 0.5–1.5 mm. long, flattened to subterete, stiffly bearded, with a scarious lobe up to 0.6 mm. long at its tip. Homogamous pairs 1 at the base of the lower raceme only. Sessile spikelet 4–6 mm. long, glabrescent to sparsely pubescent; callus cuneate, 0.5–0.8 mm. long, narrowly obtuse to acute; awn 2–3.3 cm. long. Pedicelled spikelet glabrous to shortly and sparsely pilose with, or sometimes without, an awn-point up to 6 mm. long.

Notes
H. schimperi is rather indistinctly separated from H. variabilis, of which it may be a tetraploid derivative. It includes specimens with both glabrous and sparsely pilose pedicelled spikelets, which intergrade so gradually that they can scarcely be separated; they do not approach the hoary villous condition found in H. rudis. The scarious rim of the upper raceme-base is very variable, and may, at its extreme, approach the condition found in truly appendaged species, but the latter have few-awned racemes.
