“Carex integra sp. nov. 
Very densely cespitose, the culms 1.5-3.5 dm. high, slender 
but erect, rather bluntly triangular, smooth, much exceeding the 
leaves, aphyllopodic, light brownish at base. Sterile shoots nu- 
merous, with five to eight erect leaves. Fertile culms with one or 
two old leaves at base and with three or four well-developed leaves 
just above the base, the sheaths hyaline ventrally, the blades flat, 
I-2 mm. wide, 3-10 cm. long; sterile shoots with leaf-blades much 
longer. Spikes four to eight, densely aggregated in a head I-2 
cm. long, 6-10 mm. wide, the spikes gynaecandrous, obovoid or 
oblong-obovoid, 4—8 mm. long, 3.5-5 mm. wide, rounded at apex, 
tapering at base, the perigynia ten to twenty in several ranks, 
appressed or appressed-ascending. Lowest bract slightly pro- 
longed, much shorter than head, the upper scale-like. Scales 
ovate, dark chestnut with prominent green midvein and in age 
hyaline margins, acute or short-cuspidate, nearly width of, but 
shorter than mature perigynia. Perigynia very small, 2.25~-2-75 
mm. long, 0.75-1 mm. wide, plano-convex, thickish, brownish 
tinged, lightly few nerved dorsally, nerveless or very obscurely 
nerved ventrally, lanceolate, narrowly margined to the roun 
tapering base, tapering or somewhat contracted into a slender 
beak one-half to three-fourths length of body, the margins smooth 
(or very sparingly subserrulate under a microscope), chestnut- 
brown tipped with white-hyaline apex, obliquely cut dorsally. 
Achenes lenticular, yellowish, filling perigynia, short oblong, 1-2 
mm. long, 0.6 mm. wide, short apiculate, the straight slender style 
at length deciduous. Stigmas two. 
This species bears a strong outward resemblance to Carex 
subfusca W. Boott. It is well distinguished, however, by the very 
small, narrow perigynia, and especially by the margins of body 
and beak being smooth.
