Astragalus terminalis Wats. Proc. Am. Acad. 17: 370 [Man. R. 



M. 61]. 



At an altitude of about 2000 m.

* Astragalus reventoides Jones, Proc. Cal. Acad. (II.) 5: 661. 



On high mountains, at an altitude of 2500-2700 m. A species 

 with cylindric sessile completely 2-celled pods and j^ellow flowers in 

 a lax spike ; otherwise resembling the preceding. 



Montana: Beaver Head Co., 1888, Tzveedy, y; Lima, 1895,

* Astragalus Kelseyi. 



Perennial, with a wood}^ base ; stems several, erect," branched, 

 glabrous ; leaves with 8-12 pairs of leaflets, which are oblong, about 

 I cm. long, obtuse, glabrate above and strigose beneath ; raceme 

 rather lax, with a peduncle about i dm. long ; flowers about i cm. 

 long ; calyx very short, 5 mm. long, somewhat strigose with dark 

 hairs ; sepals triangular : corolla sulphur-yellow ; pod short-stipitate, 

 cylindric, slightly sulcate on the dorsal suture, almost perfectly 2- 

 celled, fully 2 cm. long. 



Very closely allied to A. terminalis, but differs in the longer and 

 narrower pod, which is much less sulcate on the dorsal side and 

 more distinctly stipitate, in the narrower leaflets and the sparser 

 pubescence. It grows on grassy slopes, at an altitude of about 

 2000 m. 



Montana; Deer Lodge, 1892, J^. D. Kelscy ; Beaver Head Co., 

 1888, Tweedy, 8. 



* Astragalus scophioides (Jones); Astragalus arrectus scophioides 

 Jones, Proc. Cal. Acad. (11.) 5: 664. 



Resembles somew^hat A. terminalis, but is a little stouter ; it differs 

 principally in the thicker and more coriaceous pod with its long and 

 curved stipe, and lack of groove on the dorsal suture. I cannot see 

 that it is nearly related to A. arrectus. Grows at an altitude of 

 1650 m.
