’ Carex leporinella sp. nov. 
“Carex tenuirostris Olney” Bailey, Mem. Torrey Club 1: 15. 
1889 (as to plant described). 
Very densely cespitose from short creeping rootstocks, the 
culms 1.5-3 dm. high, exceeding the leaves, stiff, biennial, aphyl- 
lopodic, sharply triangular, smooth, brownish at base. Leaves 
with well-developed blades three to five to a fertile culm, on lower 
fourth and more or less bunched, the blades involute, 0.75-1-5 
mm. wide, mostly 5-10 cm. long, sparingly roughened towards 
apex. Inflorescence consisting of three to six gynaecandrous 
spikes aggregated into a head or more or less separate, the head 
erect, rather stiff, 1.5-3 cm. long, less than 1 cm. wide, the spikes 
narrowly oblong-oval, 6-15 mm. long, 3-5 mm. wide, short clavate 
at base, short pointed at apex, the staminate flowers few, the 
perigynia eight to twenty, closely appressed, the tips erect- 
appressed; bracts scale-like, the lowest occasionally short pro- 
longed. Scales oblong ovate, reddish-brown with lighter midvein 
and white hyaline margins, acute, slightly longer and wider than 
and concealing perigynia. Perigynia narrowly lanceolate, widest 
near middle of achene, 4 mm. long, scarcely I mm. wide, 
strongly plano-convex, very narrowly margined, serrulate above 
middle, finely striate dorsally, at first nerveless ventrally, at 
maturity few nerved, yellowish tinged, contracted and tapering 
at base, tapering into the short (1 mm. long), beak, which is light 
reddish tinged, not bidentate, hyaline at apex and obliquely 
cut dorsally. Achenes lenticular, oblong obovoid, 2 mm. long, 
less than 1 mm. wide, apiculate, the slender style at lengt 
deciduous. Stigmas two. 
This species bears a close outward resemblance to Carex phaeo- 
cephala Piper, but is readily distinguished by the narrowly mar-
