Glabrous, similar to C. s¢ricta but smaller, culm slender, scab- 
rous above, seldom over 2° high. Leaves 1/114” wide, rough- 
margined, shorter than or sometimes overtopping the culm, their 
sheaths slightly or not at all fibrillose; lower bract foliaceous, about 
equalling the culm; staminate spikes linear-cylindric, 6-15” long, 
about 2’ in diameter, erect or somewhat spreading, all sessile 
or nearly so, sometimes with a few staminate flowers at the sum- 
mit; perigynia orbicular, obtuse, about 4" broad, faintly 2-4- 
~nerved, minutely beaked, the orifice entire; scales lanceolate, 
purplish, spreading, very acute, about twice as long as the peri- 
gynia; stigmas 2. 
In swamps, New Brunswick to Western Ontario, south to 
Rhode Island, Pennsylvania, Wisconsin and Nebraska.

My observations on this plant lead me to believe it constantly 
different from C. virescens Muh]. As the name applied to it by 
«, U 
Schweinitz has been used before, I propose for it"CAREX COSTEL- 
LATA and give its characters as follows: 
Similar to C. virescens but taller and more spreading, culms 
slender, 1°_2 1%Z° long. Leaves 114’’-2” wide, pubescent, espe- 
cially on the sheaths, shorter than the culm, the upper one and the 
similar lower bract sometimes overtopping the spikes ; spikes 2=5; 
narrowly cylindric, many-flowered, rather loose, ¥4’-1/% long, 
1%” in diameter, erect or slightly spreading, the terminal one 
Staminate below, the lower one commonly filiform-stalked; peri- 
gynia oblong, densely pubescent, narrowed at each end, strongly 
Several-ribbed, 1’ long, rather more than yn" thick, beakless, the 
Orifice entire; scales ovate, scarious-margined, acuminate or 
Cuspidate, shorter than the perigynia; stigmas 3. 
In woods, Maine and Ontario to North Carolina, chiefly along 
the mountains. 
“ ALLIONIA BusuHI n. sp. Low, glabrous, somewhat fleshy; stem 
Nearly white, diffusely branched, about 8’ high, the branches 
slender, widely divergent; leaves narrowly linear, sessile, 1-3’ long, 
1’’_114” wide, blunt, their width almost uniform from base to 
pex; involucres clustered at the ends of the branches, at first 
campanulate and longer than the flowers, at length rotate ane be- 
_€oming 10” broad, membranaceous, pubescent, finely reticulate- 
_ Veined, their 3 short lobes semi-circular, rounded, the mid-veins 
_ prominent.
