long, £-1/ wide ; raceme frequently 1-2° long ; bracts oblong-lanceo- 

 late, equalling or shorter than the calyx ; flowers mostly scattered, 

 blue, purple, or white ; pedicels 3 - 6" long ; calyx-lips subequal, en- 

 tire, bractlets very caducous ; petals equal, 6 - 7" long, keel naked ; 

 ovules 9 ; pod 1' long or more. — From Ft. Vancouver and the Lower 

 Fraser River to Klamath Valley and San Francisco. 



8. L. Wtethii. Stem ascending, stout, \ - 2° high, sparingly 

 leafy ; pubescence villous, spreading ; stipules setaceous ; leaflets 8 — 12, 

 oblong to oblanceolate, \\-2\' long, acute, glabrous above, the lower 

 petioles much elongated; raceme 4-10' long, often long-peduncled ; 

 bracts subulate-setaceous, exceeding the calyx ; flowers blue or pink, 

 scattered or subverticillate ; pedicels slender, 3— A" long; calyx vil- 

 lous, with short setaceous bractlets, upper lip 2-toothed, the lower one 

 longer, subentire ; petals equal, 6 - 7" long, keel naked ; ovules 7-8. 

 — Flathead River, Oregon (Wyeth) ; Clear Water (Spalding). 



9. L. rivularis, Dougl. Stout, erect, 2-6° high, branching, 

 nearly glabrous ; pubescence short and silky, close-appressed or very 

 rarely spreading on the calyx and pedicel ; stipules subulate or seta- 

 ceous ; leaflets 7 - 10, about equalling the petioles, \ - 5' long, oblanceo- 

 late, acute or the lower ones obtuse, glabrous above ; raceme long- 

 peduncled, often 1-2° long ; bracts setaceous, exceeding the calyx ; 

 flowers scattered or subverticillate, purple or sometimes white ; pedicels 

 2 - 5" long ; calyx with caducous bractlets^ the upper lip rarely entire ; 

 petals 6" long, equal, the keel slightly ciliate ; pod 1^' long, 8 - 10- 

 seeded. — From the Columbia to Southern California, common. The 

 species has been known only from the figure (Bot. Reg. 19, t. 1595) 

 and a cultivated specimen in Herb. Lindley. These seem to accord 

 sufficiently well with the ordinary L. cytisoides, Agh., and the older 

 name is retained. 



Var. latifolius. Leaflets 5 - 7, 'spatulate or oblanceolate, \ - 1 y 

 wide, obtuse and mucronulate, or the upper acute, the pubescence on 

 the calyx oftener spreading. 



10. L. Burkei. Resembling the last, but distinguished by broader 

 stipules, the lower leaves long-petioled, the raceme usually short and 

 dense, with pedicels mostly but 1 - 2" long, bracts villous and subper- 

 sistent, pubescence of the calyx somewhat villous and more or less 

 spreading ; pod 8-seeded. — On the east side of the Sierra ; near 

 Carson City (46 Anderson, 262 Stretch); "Snake country " (Burke) ; 

 Falls of the Yellowstone (Hayden).
