es 1 in. long, hardening into woody creeping rhizomes. Stems 18-36 in., at 
top i-pin. in diam. with 3 concave faces. Leaves usually few, topmost 2-6 in. 
eect, green, sword -shaped, shortly caudate. Umbel 2-6 in. in diam., simple com- 
pound or congested ; bracts 3-5, up to 6 by 2 in., lowest usually erect (till fruit- 
tine). Spikes of 4-10 spikelets, rhachis glabrous. Spikelets $-} by 35x% in.

3; anthers linear-oblong, not crested. Nut trigonous, becoming black; style $ 
length of nut; branches linear, slightly exsert.—This perhaps from its short leaves 
5 more nearly allied to (C. tegetiformis, Roxb., but differs in the very narrow wing 
to rhachilla, Easily recognized, when dry, by the glumes (though closely packed) 
ing forced apart by their edges being crispidly incurved all round.—Cyperus, 
(tb. Deser, et Ic. p. 40, t. 11, fig. 3, is adduced here by various authors; but I
