ing scarcely to the beak or about half the length of the

 lowish green. The lower pistillate spikes are sometimes

This species is clearly different|from C. lupulina, Muh., 

 the C. lurida, Wahl. It more nearly resembles C. gigantea, 

 Muh., but differs from it in several obvious characters.

Spicis distinctis, tristigmaticis ; spicis staminiferis binis, 

 suprema longa gracile pedunculata ; spicis fructiferis qua- 

 ternis oblongis cylindraceis subapproximatis incluse pe- 

 dunculatis subpendulis cum bracteis longis poliaceis ; fruc-

Culm 6—12 inches high, triangular, scabrous above, 

 very leafi/ ; leaves linear lanceolate; nearly flat, scabrous 

 on their edges, with striate sheaths ; staminate spikes two, 

 sometimes one, the highest long, slender and pedunculate, 

 the other short, sessile, and sometimes pistillate below with 

 a slender, filiform, scabrous bract long as the spike ; stam- 

 inate scale oblong-lanceolate, brownish, white on the edg- 

 es ; stigmas 3 ; pistillate spikes 3—5; usually 4, long, cy- 

 lindric, rather near, somewhat pendulous, rather loose 

 flowered, upper one sessile, the middle ones shortly and 

 exsertly pedunculate, the lowest often rather remote and 

 pretty long — exsertly pedunculate ; bracts long, leafy, flat, 

 scabrous on their edges, surpassing the culm, with rather 

 short, striate sheathes ; fruit ovate-oblong, attenuated 

 above, beaked, ventricose. nerved, glabrous, 2-forked, pis- 

 tillate scale lanceolate, subulate, somewhat bristle form, 

 subscabrous, and about two thirds as long as the fruit ; the 

 whole plant glabrous, sub-decumbent, and its colour yel-
