* * * * Staminate spike 1; pistillate spikes globose or short 
cylindrical; perigynia firm and hard in texture, uninflated, hirsute, 
the straight beak bidentate; stigmas 3. 
+ Perigynia globose or ovoid, trigonous.

Culms slender, scabrid, 1-3 dm. tall; leaves 2-8 mm. wide, 
longer or shorter than the culms; bracts slender, the lowest 
exceeding the infloresence, or shorter; pistillate spikes 1-3, 
loosely 2-9-flowered, the uppermost sessile, and approximate 
to the staminate spikes, the others pedunculate; scales equalling 
or exceeding the perigynia, green with purple margins, lance- 
olate, acute or cuspidate; perigynia green, 4 mm. long, stipe- 
lke at base; achenes palid, granular-roughened, conformed to 
the perigynia. 
Dry hills at Santa Barbara, March, 1861; 302, 303 Brewer. 
North to Oakland, and in the Yosemite Valley. In Brewer’s 
specimens the perigynia are so sparsely hirsute as to appear 
glabrous on a casual inspection. Northern specimens are more 
densely clothed.

Culms smooth, erect, 3-6 dm. tall; leaves glaucescent, niin- 
utely scabrid, prominently many-nerved, 1-3 mm. wide, shorter 
than the culms; lowest bract grass-like, sheathing at base, the 
upper artistate from a searious base; staminate spike erect, 
1.5-2 em. long, sometimes having a small basal spike; pistillate 
spikes 2-5, the uppermost subsessile, approximate, the lowest 
remote on a long or shorter pedunele, 1-3 em. long; scales 
shorter and narrower than the perigynia, castaneous with green 
midvein and hyaline margins, ovate, concave, acute or mucron- 
ate, serrate on the back; perigynia greenish, ovoid, nerved in 
the intervals, 3-5 mm. long, terminating in a short, bidentate 
beak; achenes closely conformed to the perigynia. 
Growing in clumps, and common_on dry hillsides throughout 
the Cismontane region, below 2,000 ft. alt., from San Diego to , 
Santa Barbara, where, probably, the type was collected by
