Information
Loosely tufted perennial; culms 30–60 cm. high, geniculately ascending. Leaf-blades flat, 5–15 cm. long, 2–5 mm. wide, glabrous or hairy. Panicle narrowly oblong, 7–15 cm. long; pedicels glabrous or pilose. Spikelets oblong, 2–3 mm. long, pubescent to pilose with hairs exceeding the tip by up to 1 mm.; lower glume a little oblong scale 0.3–0.5 mm. long, inserted close to the upper glume; upper glume gently curved on the back, thinly chartaceous with a membranous tip, scaberulous on the margins, emarginate, with or without an awn up to 2 mm. long; lower floret barren, with or without a palea (its keel scaberulous), the lemma similar to the upper glume with an awn 2–7 mm. long.

Notes
The species is intermediate between Melinis ambigua and Rhynchelytrum longisetum, having the spikelet texture of the former but the shape and nervation of the latter; occasional specimens with 6 nerves are difficult to allocate. A hybrid origin seems likely, and its claim to specific rank is tenuous.
