MACKENZIE: NOTES ON CAREX 613 
candrous, ovoid, rounded at base, round tapering at apex, 6-10 
mm. long, 4-6 mm. wide, the staminate flowers few, the perigynia 
ten to twenty in several to many rows, appressed or in age 
appressed-ascending, the beaks not spreading; one to several of 
lower bracts conspicuous, dilated at base, brown with hyaline 
margins, the tips shorter than or occasionally exceeding head. 
Scales ovate, obtuse or acutish, reddish brown with lighter center 
and hyaline margins, slightly narrower and shorter than perigynia. 
Perigynia dull green or soon yellowish brown, narrowly ovate, 
thick, plano-convex, 4 mm. long, 1.5 mm. wide, finely few nerved 
dorsally, nerveless or essentially so ventrally, round-tapering at 
base, tapering somewhat abruptly into the bidentate beak, nar- 
rowly margined (serrulate above) from base, the beak one third 
length of body, slender, serrulate below, chestnut tinged, obliquely 
cut and hyaline at apex. Achenes lenticular, thick, short oblong, 
1.75 mm. long, 1.2 mm. wide, apiculate, the slender style at

This species is closely related to Carex gracilior, described 
below, but is a much more robust plant with a more capitate 
head and wider leaf-blades. It is a plant of the Coast Ranges and 
extends from Santa Barbara County on the south to Mendocino 
County in the north. A specimen collected by Bolander at Oak- 
land and in the Columbia College herbarium is taken as the type.
