I think it will be found that this feature cannot be too closely 
relied upon. 
Jepson (Flora Mid. West. Cal.) has confined his description 
of hesperium to the puberulent stemmed coast form. Gray has 
included the hispid-hirsute leaved forms under the same name. 
I think it will be found when the seeds are examined that all 
the hispid forms are Hansenz. D. hespertum is properly a Coast 
Range form, ranging from Vacaville to San Jose (Jepson), while 
D. Hanseni (if all the hispid forms belong here) is a plant of 
the eastern and southern mountains towards the Sierras, and 
south as far as Kern county. The following list indicates the 
probable distribution of D./Hamnsenz. Mariposa county, June, 
1895, Congdon; Keweah River Basin, April, Hopping; Yosem- 
ite, June, 1875, McLean; Milton Canyon, Calaveras county, 
1321 Davy; Tuolumne river, 2095 Blaisdale; Agricultural Sta- 
tion, Amador county, 104 Hansen; foothills, Butte county, 1913 
Bruce; hillside, Copperopolis, Calaveras county, 1369 Davy; 
Putah Creek, Solano county, 5581 Heller; Kern River Canyon, 
_Kern county, April, 1900, G. D. Abrams. 
D. HANSENI var. ARCUATUM Greene. Two specimens in 
the University of California herbarium from Mountain Ranch, 
Calaveras county, 1608 Davy, and Little Yosemite, July, 1875, 
McLean, are apparently good specimens of this variety. 
ID. HANSENI var. kernense n. var. Perennial, stout, 1-2 
feet high, root deep, ligneous: stem lead colored, puberulent: 
basal leaves numerous, ovate in outline, moderately cut into 
broad segments with mucronulate or acute tips, very hoary with 
a hispid-hirsute pubescence, especially on petioles and under 
surface of leaves: stem leaves about four, on long (four inch) 
petioles: inflorescence strict, moderately compact: flowers mi- 
nutely puberulent externally, very pale lavender, % inch long, 
sepals, petals, and spur of about equal length, the latter sharply 
recurved: fruit unknown. 
Mt. Cummings, Tehachapi mountains, 6000 feet altitude, 
on a dry sunny slope, 1703 Hasse and Davidson (type); Hall and 
Babcock 5065, Greenhorn range, Kern county, is evidently this 
_ same variety, though the flowers are of a darker color. 
D. CuYAMACAE Abrams. A good species, only represeuted 
by the paratypes in the Stanford herbarium.
