27. L. Andersoni, Watson. About 1° high, slender, much branched 

 and leafy, minutely pubescent ; stipules small, subulate ; leaflets 7-9, 

 oblauceolate, f — \\' long, acute or obtuse and mucronulate, pubescent 

 both sides; raceme becoming 6' long; flowers subverticillate or scattered, 

 pedicels 1 - 2" long ; calyx campanulate, not at all saccate, obscurely 

 bracteolate, lips subequal, upper broad and shortly toothed, lower sub- 

 entire ; petals blue or pink, equal, 4" long ; banner and keel naked ;

 ginate, mucronulate; the whole plant densely silky-villous. — Clark's 

 Ranch, Mariposa Valley, California (Dr. Gray). 



28. L. parviflorus, Nutt. Strict, erect, slender, 2-3° high, at 

 length branching ; pubescence scanty, short, appressed, the calyx and 

 pedicels silky ; stipules setaceous ; leaves rather distant ; leaflets 

 5-11, oblanceolate to obovate, 1 - 2' long, acute or obtuse and mu- 

 cronulate, glabrous above, the lower leaves shorter than the petioles ; 

 raceme ^ - 1° long, slender ; bracts linear-subulate, equalling the calyx ; 

 flowers subverticillate or scattered, the slender pedicels 1 - 2" long ; 

 calyx-lips nearly equal, the upper 2-toothed ; petals light-blue, equal, 

 3 - 4" long, keel ciliate or naked ; pod § ' long, 2 - 4-seeded, pubescent. 

 — In the mountains from the Columbia River to Northern Utah and 

 the Yosemite Valley. Stems usually solitary, the root-stock probably 

 creeping. 



29. L. calcaratus, Kellogg. Stems rather stout, 1-2° high, 

 ascending, branched, puberulent ; leaves more or less silky on both 

 sides; stipules subulate or setaceous; leaflets 6-12 (about 9), oblan- 

 ceolate, 1 - 2' long, acute, at least half as long as the petioles ; racemes 

 3-6' long ; bracts subulate ; flowers verticillate or scattered, on pedi- 

 cels 1 - 3" long ; calyx silky-pubescent, conspicuously spurred, upper 

 lip shortly toothed, the lower subentire, a little longer ; bractlets small, 

 setaceous ; petals white or blue, the banner pubescent, 6" long, exceed- 

 ing the wings and ciliate keel ; ovules 4- 6 ; pod f - 1' long, hairy. —
