Information
Densely caespitose perennial, the basal sheaths glabrous to tomentose; culms 15–120 cm. high, erect. Leaf-blades setaceous and crowded into a basal tussock, 5–30 cm. long, the larger plants also with flat cauline leaves 2–4 mm. wide. Panicle linear to narrowly oblong, 4–26 cm. long; pedicels glabrous or pilose. Spikelets narrowly oblong to narrowly ovate, (3–)4–5 mm. long, densely villous with silky white, pink or purple hairs extending 1–4 mm. beyond the tip but the lower half sometimes merely pubescent; lower glume a little ovate or oblong scale up to 1 mm. long, mostly concealed by hairs, usually inserted close to the upper glume; upper glume gently curved on the back, chartaceous with a membranous tip, minutely emarginate, mucronate or inconspicuously awned (up to 4 mm.); lower floret ♂, its lemma resembling the upper glume and usually separated from it by a very short internode, its palea ciliate on the keels.

Notes
The species can be recognized by its densely caespitose habit. Specimens with the leaves all basal and setaceous (R. setifolia) are often treated as distinct from taller plants with some of the leaves cauline and flattened. However there is no clear dividing line between the two, and the latter seems to be no more than a luxuriant growth form; both forms show a parallel range of spikelet variation. R. rhodesianum (Rendle) Stapf & Hubbard from Zimbabwe and South Africa has the spikelets glabrous below and merely pubescent above with hairs scarcely exceeding the tip. In other respects it resembles R. nerviglume, and its claim to specific rank is open to doubt.
