times longer ; banner broader. — Intermediate between L. aridus and 

 L. minimus. In the high Sierras of California. 



Var. Utahensis. Racemes 3-6' long, shorter than the very long- 

 petioled leaves ; bracts setaceous, exceeding the flowers ; petals pur- 

 plish, 4" long, the banner shorter. — Parley's Park in the Wahsatch 

 (Watson). 



36. L. Kingii. Stems apparently from a perennial subterranean 

 rootstock, diffusely branched, leafy ; pubescence villous, spreading ; 

 leaflets oblong-lanceolate, f - 1/ long, acutish or obtuse, the petioles 

 twice longer ; racemes on slender peduncles equalling the leaves ; 

 bracts short ; calyx nearly equalling the petals, the lower lip equally 

 3-toothed ; petals purplish, 4" long, the narrow rhomboidal banner 

 shorter than the wings ; ovules 2 - 3 ; pod ovate, 5" long, 1 - 2-seeded. 



— Iieber Valley in the Wahsatch (Watson). At first mistaken for the 

 last, which it much resembles. 



37. L. minimus, Dougl. Appressed silky-villous, 3-6' high ; 

 leaflets 5-9, obovate or oblanceolate, 3 - 8" long, mostly acutish, the 

 petioles 3-4 times longer ; peduncles equalling or exceeding the 

 leaves ; bracts short, deciduous ; calyx half the length of the petals, 

 upper lip deeply bifid ; petals purple, 4 - 5" long, equal, the banner or- 

 bicular. — Oregon and Washington Territory. 



38. L. Breweri, Gray. Stems 2 - G' long, from a spreading 

 branched woody caudex, very leafy ; pubescence dense, silky, 

 appressed ; leaflets 7 - 10, obovate, obtuse, 4 - 6" long, the petioles 

 1-2 times longer ; racemes very short, peduncles equalling the leaves ; 

 bracts short ; calyx-lips nearly equal, the upper deeply bifid, the lower 

 shortly and equally toothed ; petals blue, equal, 3 - A" long, the ban- 

 ner orbicular. — Sierra Nevada, California; alpine. 



39. L. Lyallii, Gray. Stems leafy, from a spreading woody cau- 

 dex ; pubescence dense, villous, appressed ; leaflets 5-6, obovate, 

 3 - 4" long, acutish, the petioles 3-4 times longer ; racemes very 

 short, the peduncles much exceeding the leaves ; bracts short ; calyx-lips 

 nearly equal ; petals purple, 5" long, nearly equal, the banner elliptical. 



— Summit of the Cascade Mountains, Washington Territory (Lyall). 

 Var. Danaus. {L. Danaus, Gray.) Stems less leafy ; jmbescence 



rather sparse ; petals nearly white, the keel tipped with dark-purple. 



— Mt. Dana, California, at 12,500 feet altitude. The comparison of a 

 larger amount of material may modify the definition of some of these 

 alpine species.
