The originals of this large and handsom aconite are of Mr. C. F. 
Baker's collecting near Pagosa Peak, southern Colorado, 3 Aug., 
1899, where they were obtained at an altitude of 9000 feet. Mr. Ryd- 
berg printed the name in his Flora of Colorado, but with hardly an 
adequate description.

limbus profunde 5-partitus, segmentis profunde subpinnatifidis; flores 
3—5 mediocres atrocyanei; sepala anteriora late lanceolata, deflexa,

Baldy Peak, otherwise known as Pecos Baldy, east of Santa Fe, 
New Mexico, at 11000 feet, collected by Vernon Bailey, 25 July, 
1903. Remarkable among American members of the genus for its fairly 
pinnatisect leaf segments, by which the leaf as a whole recalls that of 
Geranium Robertianum.,

Low meadons at the forks of St. Mary's River, region of the Cœur 
d'Alene Mountains, Idaho, collected by J. B. Leiberg, 6 July, 1895, the 
plant in full flower. The species is well distinguished from all others 
by its fine yet alinost velvety pubescence, large greenish and blue flowers, 
and remarkably dissimilar unusually large anterior sepals.
