Cespitose; culms slender, 3-5 dm. tall; leaves flat, 3-5 mm. 
wide, shorter than the culms; staminate spikes 1-3, the terminal 
2-3 em. long, the others much shorter; pistillate spikes 1-3, 
spaced, 1-4 em. long, 3-5 mm. thick; scales shorter than the 
perigynia, oblong, obtuse or emarginate; perigynia ellipsoidal, 
or sometimes broader in the same spike, faintly nerved, 3 mm. 
long; achenes oblong. 
Collected at high altitudes in the San Jacinto Mts., July and 
Aug., 1901, by Mr. H. M. Hall. 2461, Tahquitz Valley, 7,000

Stoloniferous by slender rootstocks; culms slender or fili- 
form, 25-50 em. tall; leaves thin, scabridous on the margins, 
2-4 mm. wide, long-pointed, much shorter than the culms; 
bracts similar, the lowest slightly surpassing the infloresence; 
staminate spike oblong, acute, 1 em. long, peduneulate; pistil- 
late spikes 1-5, cylindrical, the terminal often having 2-3 very 
short sessile spikes at base, the lowest remote and usually on 
a long pedunele; scales shorter than the perigynia, green with 
brown margins, ovate, cuspidate; perigynia green, obovoid, 
strongly nerved, 2-5 mm. long; achenes conspicuously beaked, 
filling the perigynia. 
The type was collected by Dr. H. EH. Hasse, in a bog near the 
head of the West Fork of San Gabriel River, 4,500 ft. alt. July, 
1894. Seven Oaks, 6,000 ft. alt., in the San Bernardino Mts. ; 
Hasse. In wet meadows, San Bernardino valley, 1,000 ft. alt.: 
Parish. The relationship of this plant is with C. aurea, rather 
than with C. laxiflora; it is too near C. aurea celsa, Bailey, Mem. 
Torr. Club, 1:75, indeed apparently identical with it.
