brous ; pistillate scale ovate, distinctly mucronate below, less in 
the middle of the spike, and often only acutish at the summit, 
green on the keel, shorter than the fruit. Colour light green.

Spicis staminiferis subbinis oblongis erectis sessilibus ap- 
proximatis a fructifera remotis, suprema longiore } spica fruc-

Culm 1—2 feet high, erect, acutely triquetrous, minutely 
scabrous, purplish towards the base ; leaves linear-lanceolate, 
about half as long as the culm, shorter below, rough on the 
‘edge, sheathing tewards the base ; bracts linear-lanceolate, 
leafy, shorter than the culm, with sheaths white opposite to 
the leaf; staminate spikes one to four, generally two, approxi- 
ate, sessile, lower ones short, upper one about an inch long, 
densely imbricate, remote from the pistillate spike,—with an 
oblong and obtuse scale, tawny, white on the edge, green on 
the keel, and the lower one sometimes with a few fruit; stigmas 
three ; pistillate spike single, sometimes two, erect, oblong- 
cylindric, exsertly pedunculate, somewhat loose-flowered,— 
when two, the lower remote, and the upper sometimes stami- 
nate at the apex; fruit ovate, or oval-ovate, slightly inflated, 
glabrous, nerved, sub-triquetrous,—with a short beak, red- 
dish brown, and its orifice white and oblique ; pistillate scale 
ovate, somewhat acute, sometimes rather obtuse, reddish- 
This beautiful species bears some resemblance to C. vestita, 
which has sometimes two staminate spikes ; but the spikes of 
this plant are longer and not sessile, and in most o its cha- 
racters it differs from any American species hitherto de- 
scribed :
