Information
Stolons 0. Stems 1–2 ft. long, annual or biennial, tufted. Leaves 2/3 the length of the stem, rarely exceeding 1/8 in. in breadth, much enrolled in all the dried examples. Umbel 1–6 in. in diam., simple or compound, or one compound head; bracts 3–5, lowest overtopping the inflorescence, similar to the leaves. Spikelets loosely spicate, 1/4– 3/4 by 1/12– 1/10 in., strongly compressed, from shining dark brown to nearly black, 8–30-flowered, with parallel sides. Glumes rigid, ovate, scarcely acute. Nut 1/2 the length of the glume, ellipsoid, apiculate, nearly black, superficial cells small, quadrate.

Notes
The species nilagiricus was originally grounded on the black-chestnut colour, while my var. nilagirica includes all the narrow spikeleted heads whatever the colour. All the Tropical African material has narrow spikelets with exactly parallel sides, and is chestnut-brown to chestnut-black. P. betschuanus differs in the prominent long stolons. The Cameroon plant, issued from Berlin as Cyperus globosus, Allioni is exactly the common form of C. nilagiricus in India.
