em. long; culm leaves 1-2, narrow, sheathing at base, 2-3 em. 
long; lower bracts similar, uppermost scarious; staminate spike 
slender, 8-10 mm. long, usually with a small pedunculate basal 
spike, both of them pistillate at base; pistillate spikes 1-3, on 
included peduneles, the lowest distant, ovoid-oblong, 5-10 mm. 
long; scales ovate, ciliate above and mucronulate, 2 mm. long; 
perigynia divergent, very dark brown, obovoid to obovoid- 
ellipsoidal, acute on the edges, 3 mm. long; stigmas 3; achenes 
ash-colored, obovoid, 3-angled, muriculate, shortly stipitate 
aud prominently beaked, fillmg the perigynium. 
Grayback Mt., on High Creek, 9,500 ft. alt., July 24, 1904; 
6405 Geo. B. Grant. The species is northern, and has been 
collected on Mt. Hood, Oregon, Stein’s Pass, Wash., and in 
this state on the head waters of the Sacramento river. The 
present station is the southern limit. 
Perigynia abruptly contracted to a short beak, and only partly 
jilled by the achene, bracts with a more or less conspicuous and 
purlish, scarious, aurtculate base, 
Perigynia membraneous, centrally tumid with the 3-angled 
achene, so that the edges appear as wings, spikes oblong, ovoid or 
clavate. 
7. Carex quadrifida ceca, Bailey, Bot. Gaz. 21:8. 
Culms slender, smooth, 3-5 dm. tall; leaves flat, 2-3 mm. 
wide, shorter than the culms; bracts aristate, seldom equalling 
the inflorescence; spikes 3-6, contiguous and sessile, or the 
lowest remote and pedunculate 1-2 em. long, the uppermost 
usually androgenous, the others pistillate throughout; scales 
mostly shorter than the perigynia, lanceolate, acute or obtuse; 
perigynia purplish, obovoid, obscurely nerved, 2.5-3 mm. long, 
the bidentate beak purple; stigmas 3; achenes olivaceous, 
ovoid, muriculate, narrowed at base, 1.5 mm. long. 
San Jacinto Mts. Tahquitz Valley, 8,000 ft. alt., July, 1892,

Hasse. Also in the same mountains by Davidson. Grayback 
Mt. on Vivian Creek, 7,500 ft. alt., 1904, Geo. B. Grant. In 
other varieties the species is common at high altitudes in the 
central Sierra Nevada.
