272 Carccography. 
This species inhabits the Alps, the mountains of England, 
&c. and was discoveredin our country onthe Rocky mountains 
by Dr. E. James. This species is very different from C. ni- 
gra, Willd. no. 115, Pers., and also from C. ustulata, Wahl. 
no. 92.

Spicis distinctis; spica staminifera solitaria erecta; spicis 
fructiferis tristigmaticis oblongis cylindraceis subsessilibus 
subremotis erectis subsparsifloris ; fructibus ovalibus utrin- 
que acutis compressis brevi-rostratis ore integro glabris, 
squamz ovato-oblonge acutiuscule subaquantibus. 
Culm about a foot high, triquetrous, subscabrous above ; 
leaves linear, striate, about as longas the culm, shorter 
below; bracts leafy, linear, lower ones equalling the culm 
with scarcely any sheaths ; staminate spike single, erect, 
short pedunculate with an oblong and obtuse black scale, 
white on the keel and edge : stigmas three ; pistillate spikes 
two to four, oblong, cylindric, erect, about sessile, rather 
loose flowered, nearly aninch long, and separated from each 
other about their length ; fruit oval, rather acute at both ends, 
compressed, glabrous, with quite a short beak and entire at 
the orifice; pistillate scale ovate-oblong, subacute, about 
equalling the fruit, nearly black, with a white edgeand white 
line on the keel. Colour of the spikes black or dark brown : 
of the plant light green, becoming brown. 
F lowers in Soon: in damp soil—found on the White 
mountains of N. H. near the summit of Mount Washington, 
by Dr. J. Barratt, Professor of Botany, &c. in the Mil. 
Acad. Middletown, Ct. 
This plant differs from C, nigra, Willd, and Pers. no. 115, 
as appears from the description there and in Rees’ Cyc. no. 
75, in its oblong, rather remote spikes, and in its fruit and 
scale. C. nigra has ovate, clustered spikes. Jt may have 
been mistaken for C. saratilis, but differs from that species 
Schk. tab. I and Tt fig. 40, as well as from its var. C. 
Bigelowi in the Analyt. Tab. of Mr. Schweinitz, in the shape 
of its spikes, fruit, and number of stigmas. Although this 
species resembles, it is, as well as the preceding, very difler- 
ent from C, ustulata Wahl. no. 92, the C. atrofusca Schk. tab. 
Y fig. 82, which, according to Mr. Schweinitz, has been 
found in Labrador.
