Cyperus nevrotropis

Stem 4–18 in. long, covered 1/4 its length by leaf-sheaths, often flowering the first year, or usually decumbent at the base, rooting and often long creeping. Leaves as long as the stem or scarcely half so long, 1/10– 1/6 in. broad. Umbel simple, usually narrow, often contracted nearly into 1 head; bracts 3, lowest 3–6 in. long, similar to the leaves. Spikelets 1/2– 2/3 by 1/10– 1/8 in., 6–30-flowered, not much compressed, greenish-brown more or less tinged with dark red. Glumes ovate, obtuse, turgid, 3–5-nerved on the back. Nut 1/3– 1/2 the length of the glume, obovoid, biconvex, ashy-brown; style longer than the nut, its linear branches long exserted; superficial cells of the nut small, subquadrate hexagonous.
