Information
Glabrous. Stems 1–3 ft. long, approximate on a woody rhizome, round, at the very top round or hardly round-trigonous. Leaves short, rarely 1/3 the length of the stem, 1/5 in. broad. Umbel 3–10 in. in diam., usually compound; bracts 4–7, usually exceeding the umbel, similar to the leaves. Spikes of 3–20 loosely arranged spikelets, often drooping. Spikelets 1/2– 3/4 by 1/8 in., compressed, chestnut-brown or bright brown, 12–24-flowered; wings of rhachilla narrow oblong, separating from the glume, finally deciduous; glumes elliptic, obtuse, not striate, in fruit very distant. Nut 1/2 the length of the glume, oblong-obovoid; style-branches 3, long.

Notes
This species is readily separated from C. longus, Linn. (with which it has been greatly confused) by the glumes standing altogether separate in fruit with their margins inrolled. The species is so close to the Indian C. tegetum, Roxb., that I can allege no difference except the remarkable roundness of the stem in C. schimperianus, which character distinguishes it also from its African neighbours.
