Rosa blanda, Rydberg, Flora, 477 and others, as to western speci- 

 mens. The true R. blanda, Ait. appears not to extend westward as far 

 as Montana (Crepin, Bot. Gaz. 22:12) ; the western form usually re- 

 ferred to that species is R. Nutkana, Presl.

LEGUMINOS^E. 



Astragalus aculealus, A. Nelson, -Bull. Torr. Bot. Club, 26:10; 

 Rydberg, Flora, 249. The wisdom of separating the red-flowered 

 forms of A. tegetarius, Wats, from the ones with the flowers "ochro- 

 leucus, the k%el purplish" of Colorado, is doubtful, judging from a 

 comparison of the types of both, as such slight variation in color is 

 rarely sufficient basis for founding a species. 



Astragalus adsurgens albifolius, n. var. 



Larger than the type; leaves canescent with a white sericeous 

 pubescence, like that of A. terminalis, Wats.; petals white or cream- 

 colored, or possibly purplish when young; calyx and fruit white, 

 somewhat lanate with short hairs ; otherwise like the type.
