20. Carex chrysoleuca, Holm, Am. Jour. Sei. 17:302, f. 3. 4. 
Culms slender, but stiff and erect, 3-angled, roughish above, 
4-5 dm. tall; leaves carimate, 3-4 mm. wide, shorter than the 
culms; heads 3-6 em. long, 5-10 mm. thick; spikes ovoid; scales 
exceeding the perigynia, the linear midvein excurrent as a 
short, rough awn; perigynia light brown, firm, distinctly nerved 
on the outer face, broadly ovoid, serrate above, abruptly con- 
tracted to a narrow, deeply-split beak, shortly stipitate, 3 mm. 
long; achenes hght brown, lenticular, broadly ovoid, puneticu- 
lose, filling the body of the perigynia.

Coldwater Canon, San Antonio Mt., Los Angeles Co., July, 
1902; 2679 Abrams. The type was collected in Mariposa Co., 
by Congdon. 
++ Staminate column less evident; heads stramineous. 
21. Carex alma, Bailey, Mem. Torr. Club, 1:50. 
Culms stoutish, rough above on the sharp angles, 4-12 dm. 
tall; leaves carinate, 3-5 mm. wide, mostly exceeding the 
eulms; heads 9-12 em. long, 10-15 mm. thick; spikes ovoid, in 
ovoid clusters; scales equalling the perigynia, oval to oval- 
oblong, acute, or with the linear midvein excurrent; perigynia 
brown, shining, nerveless, ovoid, narrowed to a long, bidentate 
beak, serrate on the sharp upper margins, thick and spongiose 
at the mostly truncate base, 3.5-4 mm. long; achenes brown, 
puncticulose, lenticular, oblong 1.75-2 mm. long. 
Growing in robust clumps along streams in the mountains 
of the Cismontane region, and ascending the Nevadan range 
to 7,500 ft. alt., Mt. Pinos, Ventura Co.; Middle Fork, 5,800 ft.

nardino Mts.; Vivian Creek, 7,000 ft. alt., July, 1904; 6399 Geo. 
B. Grant. Bear Valley, 6,500 ft. alt., Aug., 1882, and City 
Creek, 3,000 ft. alt.; 1611, 2223 Parish. The type was 396 
Parry & Lemmon, from San Bernardino Co. Some specimens 
have been referred to C. teretiuscula, Good., a species which 
probably does not occur here. When not entirely mature the 
perigynia are whitish, and 3-nerved on the back, but when 
fully mature are smooth and brown.
