California: F. W. Hubby no. 67, Ap. 6, 1896, Ojai, Santa Barbara 
Co.; E. L. Greene, June 24, 1892, Mt. Diablo, Cal. 
2. A. desertorum Davidson, l. c., p. 16. 
Annual, 4 to 6 in. high, branching from base; basal leaves narrowly 
lanceolate 1!/ to 2 in. long, 1 to 2 lines wide, tapering to a long petiole 
like base, pinnatifid or deeply toothed, stem leaves broader, sessile, ovate 
lanceolate, floral bracts ovate-lanceolate, 1 to 2 lines broad, the longest 
half the length of the capsule; calyx lobes 1 line long, flowers slightly 
longer; capsule 6 to 9 lines long, narrow linear-clavate; seeds in one 
row, grooved on angles. The whole plant greyish with closeset, short 
stiff hairs. 
The Arizona species distributed as albicaulis probably includes this 
species, which differs materially from albicauis in floral characters and 
seeds. It however does not agree with the specimens I gathered at 
Lordsburg, N. M., but the material I possess is too scanty to pass 
judgment upon. 
California: Brandegee, March 30, 1901, Signal Mt., Colorado Desert 
near boundary line: Hall no. 2788, April, 1902, Coyote Canyon, 500 ft. 
alt., western border of the Colorado Desert, Cal. 
3. A. montana Davidson, ]. c., p. 18. ] 
Annual; 12 to 15 in. high, upright, slender stems, very white and 
quite smooth to the eye, sparse hairs show under microscope: basal 
leaves 2 to 3 in. long, 4 to 6 lines wide, pinnatifid or roughly toothed 
or coarsely serrate; cauline leaves, 1 to 1!/, in. long, 2 lines wide in the 
middle, broader below and toothed on each side, narrowed at base sessile; 
petals 2 to 3 lines long, yellow, calyx lobes 1!/, lines long; floral bracts 
3, all lanceolate-ovate, entire, occasionally toothed near base and broader, 
the longest 1 line wide, equalling the capsule, the other two suecessively 
shorter; capsule clavate !/, in. long or less, 1 to 1!/, lines broad; leaves 
and capsule pubescent with soft, rather long hairs; seeds in three rows, 
brown, irregular, only an occasional one grooved: 
In vegetative appearance it most closely resembles A. pinetorum, but 
the short capsule, and long floral bract readily differentiate it from any 
other species. The type is no. 6511. H. M. Hall, Mt. Pinos, Ventura 
Co., California, 6000 ft. alt., in author's herbarium.

V (1906), p. 24, pl. XXI. 
Rhizome creeping; culms slender and lax, rough on the sharp edges, 
5—6 dm tall; leaves 1—3 mm wide, shorter than the culms; spikes in 
a dense ovoid head, about 2 cm long and 1--1,5 cm thick; scales a 
little shorter than the perigynia, byaline, with a brown midvein, ovate, 
acute; perigynia brown, suborbicular, strongly nerved on the exterior
