*Lupinus Hellerae Heller, Bull. Torr. Bot. Club, 25: 265. 



In sandy soil, at an altitude of 1000-1500 m. It resembles L. 

 sericeiis in flowers and leaves, but the stem is much lower, bearing 

 only one or two stem leaves and many basal ones. The habit is 

 therefore more like the western L. Icp/dus Dougl. 



Montana: Belt Mts., 1888, R. S. Williams, J41 ; Deer Lodge, 

 1888, Traphagcn (the latter specimen more loosely hairy than the 



type). 



Lupinus decumbens Torr. Ann. Lye. N. Y. 2 : 191 ; Lupintis 



argentetls d€Cumhens\N:i{s. Proc. Am. Acad. 8: 532 [Man. R. 



M. 54]. 



Open prairies and plains, at an aUitude of 1000-2500 m.

 127.

Lupinus argenteus Pursh, Fl. Am. Sept. 468 [Man. R. M. 53 ; 111. 



Fl. 2: 269; Bot. Cal. i: 121; Wats. Rev. 532]. 



Open prairies and hills, common, at an altitude of 1000-2000 m. 

 It is doubtful whether the name L. argenteus belongs to this species 

 or the preceding. The species so named here is without any ques- 

 tion, however, the same as L. tenelhis Nutt., and the latter has al- 

 ways been regarded as a s3-nonym of L. argenteus.
