Hab. Alpine riyulets on tlie eastern declivity of the Rocky Mountains, between lat. 52*> and ^5°. Drum^ 

 mond. — This, as all the other species of TroUius, is glabrous, erect, and perennial, with both radical and 

 cauline leaves petiolate and palmate, the scgfments mnltifid. The flowers are terminal. The sepals (petals 

 of Linn.) so spreading, that the species ill deserves the generic appellation of Globe Flower; usually in 

 the wild state about five in number ; but in cultivation ten are sometimes observable. De Candolle describes 

 them of a yellow colour, and the Bot. Mag. represents them of a pale sulphur, tinged with red externally. 

 In the specimens found in the Rocky Mountains, Drummoud affirms the blossoms to be white. The petals 

 (nectaries of Linn.) are shorter than the stamens, and from ten to fifteen in number, which character princi- 

 pally distinguishes this from the closely allied spedes T, patulus, in which the petals are fi-om one to five. 

 Li T. asiaticus, the sepals are also somewhat patent, but the petals are much longer than the stamens.
