the spikes ten to twenty, all closely aggregated, and the upper 
scarcely distinguishable, gynaecandrous, ovoid, rounded at base, 
rounded or tapering at apex, 6-10 mm. long, 4-6 mm. wide, the 
staminate flowers few, the perigynia ten to thirty in several to 
many rows, appressed-ascending or in age spreading, the beaks 
not conspicuous; one to several of lower bracts conspicuous, 
dilated and brown with hyaline margins, their tips usually shorter 
than or rarely little exceeding head. Scales ovate, acute, reddish 
brown with lighter midvein and very narrow hyaline margins, 
about width of and somewhat shorter than perigynia. Perigynia 
dull green or soon yellowish brown, narrowly ovate, thick and 
strongly plano-convex at maturity, 4.25 mm. long, 1.5 mm. wide, 
several nerved ventrally, strongly finely nerved dorsally, round- 
tapering to a substipitate beak, tapering into the bidentate beak, 
narrowly margined (serrulate above) from base, the beak one 
fourth length of body, slender, serrulate below, chestnut-tinged, 
obliquely cut dorsally and hyaline at apex. Achenes lenticular, 
thick, short-oblong, 2 mm. long, 1.25 mm. wide, apiculate, the 
slender style at length deciduous. Stigmas two. 
This is a species only reported from near the coast. So far 
it has been found between Sonoma County on the north and 
Monterey County on the south. The bracts are often quite 
conspicuous. A specimen collected by Messrs. Kellogg and Har- 
ford (No. 1173) in 1868-9, and preserved at the New York Botan- 
ical Garden is taken as the type.
