Tufted perennial, the basal sheaths soon falling away; culms stout, 1–2 m. high. Leaf-blades broadly linear to narrowly lanceolate, 25–45 cm. long, 8–30 mm. wide, smooth, rounded to cordate at the base; ligule 1–2 mm. long. False panicle globose to obovate, 6–20 cm. long, very dense; racemes 8–15 mm. long, the lowermost internode and pedicel connate in their lower half but not swollen. Sessile spikelet narrowly elliptic, 3–4 mm. long; lower glume membranous, narrowly winged, flat on the back with a shallow median groove towards the base, without oil streaks and intercarinal nerves or these obscure and confined to the tip; upper lemma entire, the awn 3.5–8 mm. long, fine, without a column.

Notes
A distinct species recognized by its globose inflorescence, flat lowermost rhachis-internode and entire upper lemma. C. stypticus (Rendle) Fritsch from Angola is very similar, but has an elongated inflorescence and the upper lemma is minutely 2-toothed, suggesting introgression from C. giganteus.
