toothed or nearly entire ; petals 5" long, the banner rounded, naked, 

 the keel ciliate ; ovules 5. — San Francisco Mts., Arizona (Sitgreave, 

 1851 ; Wheeler, 1872) ; Copper Mines, New Mexico (Bigelow). To 

 this perhaps belongs also 2012 Brewer, from Ebbett's Pass in the 

 Sierra, scarcely at all villous and the keel naked, as also 1020 

 Wright, from the mountains of New Mexico, resembling Brewer's 

 plant, but with the stipules longer and more conspicuous. 



18. L. barbiger. Pubescence upon the stem, pedicels and petioles 

 dense, of short, stiffish, spreading hairs, upon the leaves and calyx silky- 

 hairy and subappressed ; stipules setaceous ; leaflets 5-7, narrowly 

 oblanceolate, silky on both sides ; raceme rather dense, short-pedun- 

 cled ; pedicels 2 - 3" long ; bracts setaceous, exceeding the- calyx ; 

 lower calyx-lip narrow, subentire, slightly longer than the broader 

 rather deeply toothed upper lip ; petals 5" long, ochroleucous, equal, 

 the banner rounded, silky, the keel copiously ciliate ; ovules 7. — Col- 

 lected in Kane County, Southern Utah, 1873, by A. L. Siler. 



19. L. ornattjs, Dougl. Stems decumbent or ascending; pubes- 

 cence usually short, more or less silky, mostly appressed ; stipules 

 setaceous ; leaflets 5-7, oblanceolate or cuneate-oblong, f - 2' long, 

 acute or acutish : raceme 8-8' long, usually short-peduncled ; bracts 

 short, subulate or ovate ; pedicels 2 - 3" long ; bractlets setaceous ; 

 calyx-lips nearly equal, the upper rather shortly toothed or bifid, the 

 lower subentire; petals blue, equal, 5 - 1" long, the banner acutish, 

 subsilky on the back, keel ciliate ; ovules 5-8 ; pod 1\' long, 3 - 4" 

 wide. — From the Columbia River to Southern California. 



L. leucopsis, Agh., collected by Douglas in " Oregon and Rocky 

 Mts.," appears to be the same. Specimens from Clark's Ranch, Mari- 

 posa Valley (Dr. Gray), may probably be referred here as an extreme 

 form, being densely tomentose, the leaflets nearly obovate, and banner 

 but slightly bearded. 



Var. glabratus. Leaflets glabrous above, cuneate-oblong, acutish 

 or obtuse ; flowers nearly white, with a dark-purple spot upon the 

 banner. — Common in the Rocky Mountains of Colorado. 



d. Leaves distant ; lower petioles elongated.; leaflets not smooth 

 above ; racemes mostly dense ; flowers smaller and not yellow 

 (except in L. sulphureus) ; ovules 4-6. 



20. L. sulphureus, Dougl. A not fully identified species. De- 

 scribed as with 13-15 densely silky leaflets, keel naked and banner
