272 LEGUMINOSAE 



lonp, barely 1% to 1\ linos wide, ovules 9 to 12; seeds pale fleslicdlor. — Sandy plains, upper San 

 Joaquin Valley in Kern Co. and western Fresno Co.: Sivert sta., Kern Co., Jcp.son 11,007; Bena, 

 Kern Co., Jcpson 11,613; Caliente, Jepson C758; Rose sta., Jepson 8939, 12,425a; Coalinga, 8w. 

 Fresno Co., Jepson 15,351. At the head of the San Joatjuin Valley, on the sloping plain near 

 Tejon Pass and on the plain between IJakersfield and Caliente, this variety, in a favorable spring, 

 covers many thousands of acres with a fairly uniform stand, forming a color spectacle not 

 matched by any other Lupini. Individuals often liave numerous stems from the base which 

 branch low, forming dense clumps 10 to 18 inches high and 2 to 4 feet broad. 



Var. vallicola C. P. Sm. Flowers 3 to 5 lines long; banner little reflexed, making an acute 

 angle with the upper margins of the wings (that is, corolla "notch" slight) ; keel strongly 

 curved; seeds pale. — Grassy gravelly banks, 50 to 5000 feet: Sierra Nevada foothills from 

 Shasta Co. to Kern Co.

Var. apricus C. P. Sm. Flowers 3 to 4 lines long; banner apex well reflexed from upper 

 edges of wings (that is, corolla "notch" strong); pods 7 to 12 lines long; seeds dark. — Open 

 grassy fields, valleys and foothills, 50 to 2000 feet: Santa Barbara Co.; Monterey Co. to Trinity 

 and Shasta Cos. ; Sierra Nevada foothills. North to southwestern Oregon.

34. L. bicolor Lindl. Dove Lupine. Stems 1 to several from the base, erect 

 to diffuse, 4 to 16 inches high; herbage villous, the leaves pubescent on both sides; 

 leaflets 5 to 8, oblanceolate, 5 to 10 lines long; raceme with 1 to 3 remote or discrete 

 whorls, the flowers rarely scattered; flowers 2 to 4 lines long; lower calyx-lip entire 

 to 3-toothed; upper calyx-lip cleft into 2 broadly lanceolate acuminate lobes; corolla 

 blue, the banner with a central white spot; wings narrow; keel slender, the acumen 

 strongly bent upward, ciliate on upper edge; pods densely hairy, 7 to 10 lines long; 

 ovules 5 to 7. 



Sandy or clay soils, grassy hills and valley levels, 20 to 2000 feet: nearly 

 throughout cismontane California. North to British Columbia, south to Lower 

 California. Mar.-May. 



Note on variation. — This assemblage is on the whole very uniform in habit and inflorescence. 

 It is variable in pubescence of the herbage, slightly so in size of the flower, in number of cilia 

 on the keel, and in the degree of dentition of the lower lip. The published varieties on the whole 

 represent the limits of variation in these particulars rather than well-established geographic 

 races. When the lower lip is somewhat definitely 3-dentate, then the plant becomes var. tri- 

 dentatus Eastw., but this character is variable and the form has no definite geographic signifi- 

 cance, nor has var. microphyllus C. P. Sm. in which the flowers are slightly smaller than in the 

 typical form of the species. In var. trifidus C. P. Sm., the lower calyx-lip is 3-lobed about half- 

 way down, a somewhat more extreme state associated with sandy soil along the coast from 

 San Francisco to Monterey. The keel is often only slightly ciliate and in var. pipersmithii C. P. 

 Sm. this organ loses its last few hairs according to the character. The var. tetraspermus 0. P.
