shorter than the perigynia, ovate at base, attenuate to a rough 
awn; perigynia ovoid-eliipso:dal, prominently many-ribbed, 
stipitate, and at maturity reflexed, the body 3 mm. long, taper- 
ing into a long slender beak 1.5 mm. long, the divergent and 
recurved subulate teeth as long as the beak; achenes sharply 
triquetrous, 1.5 mm. long. 
Perhaps only a waif. A single plant, growing in swamy soil, 
by a roadside, near San Bernardino, 1882; Parish. Reported 
by Davidson, in Pl. Los Ang. Co. 30, from Burbank, but there 
is no specimen in his herbarium. In the Atlantic States from 
Newfoundland to Louisiana; on the Pacific coast from Oregon 
to San Francisco. 
“ ++Perigynia hirsute, obovoid, completely filled by the achene.

Culms tufted, smooth, 5-10 dm. tall; leaves flat, rough on 
the edges, 3-5 em. wide, equalling the culms; bracts similar, the 
lowest exceeding the culms, the upper narrow; staminate spike 
3-4 em. long, often with 1-2 short spikes at base; pistillate 
spikes 2-5, cylindrical, 1-3 em. long, 7-8 mm. thick, sessile, or 
the lowest remote on a short peduncle; scales longer than the 
perigynia, glabrous, narrowed to a rough awn; perigynia 
fuscous, the body 3 mm. long, shortly stipitate at base, tapering 
into a beak 1 mm. long, the teeth glabrous, erect, 0.5 mm. long; 
achenes olivanceous, smooth. 
Borders of swamps in the Cismontane region, below 3,000 ft. 
alt.; apparently rare. San Bernardino Valley, and Edgar Can- 
yon, in the San Bernardino Mts.; Parish. A widely distributed 
species, from the British Possessions to the Mexican border. 
A sedge collected in 1891, by Davidson, at Los Angeles, has 
exeurrent from the emarginate apex as a short cusp, shorter 
than the perigynia, which are broader, and shorter beaked. 
Probably distinet, but further material is needed.

Cespitose; ecuims rather slender, 3-angled, slightly seabrid 
above, 8-10 dm. tall; leaves hirsute, 5-6 mm. wide, shorter than 
the culms; bracts slender, the lowest exceeding the eulm; 
staminate spike 5-6 em. long; pistillate spikes 2-4, eylindrieal, 
sessile, 2-3 em. long, 5 mm. thick; scales brown with green 
midvein, hispid, acute, or the lower prolonged to a rough awn, 
as broad as the perigynia, and equalling or exceeding them;
