him in the Alleghany Mountains, since found abundantly by 
Dr. Ricuarpson in the woody country of British North 
America as far as Carlton House Fort, and by Mr. Drum- 
monp in the Rocky Mountains. The latter Naturalist sent 
seeds to this country, from which plants were raised at the 
Edinburgh and Glasgow Botanic Gardens. Another en- 
tire-leaved species with sessile anthers, was found by Dr. 
Ricuarpson on the Arctic shores, and by other Naturalists 
in North-West America: this is the D. frigidum of Cuam. 
and Scuiecur. in the Linnea : and we possess another anda 
new species of the Genus in Mr. Dovenas’ last collections 
in the interior of North-West America. 
Descr. Root perennial, throwing up a tuft of rather pale 
green, spathulate, quite entire leaves. Scape eight to ten 
inches high, glabrous, rounded, terminated by an umbel of 
from eight to ten or twelve handsome flowers. Peduncles 
spreading, surrounded by an involucre of five to seven ovate 
bracteas, and several smaller bracteas within. Flowers 
drooping. Calyx of five, spreading, ovate, acute segments. 
Corolla rotate, soon reflexed, the short tube white with a- 
yellow ring ; the limb reflexed. Filaments much exserted, 
and united into a yellow, fleshy tube, almost as long as the 
anthers: Anthers meeting in a cone, lanceolato-subulate, 
greenish-yellow, purple on the back. Germen globose : 
Style filiform, longer than the stamens : Stigma capitate.
