Hab. Kotzebue*s Sound. La?/ and Co//ze.— These specimens, from Captain Beechey's Voyage, differ 

 in no respect whatever from the numerous Siberian and Dahurian ones in my herbarium, and from others 

 gathered by Redowski, probably also on the American side of Behring's Strait. Besides the differences 

 alluded to under the preceding species, this is certainly less shrubby than P. speciosa and its more imme- 

 diate allies. The old marcescent leaves are numerous, and peculiarly flaccid and waved. 



5. P. Douglasii; humilis pubescens dense csespitosa basi fruticosa lignosa, ramis nu- 

 raerosissimis erectis, foliis arctis subulatis rigidis erecto-patentibus mucronatis inferioribus 

 marcescentibus strictis albidis, florlbus terminalibus solitariis subsessilibus, calycis villosi 

 laciniis subulatis rigidis mucronatis corollse tube brevloribus, corollae laciniis obovatis

Mountains, near the confines of snow. Douglas.— A. mo^i beautiful species, bearing copious and almost 



sessile blossoms, and intermediate in habit, as it were connecting the P. speciosa, subulata, &c. with 

 the little P. Hoodit

Hab. Common on arid, sandy, and rocky soils near the narrows of the Oakangan and Priest's Rapid of 

 the Columbia. " Flowers bright yellow! " — A very singular and most distinct species.

Hab. Sandy plains, Carlton House Fort, and other places in lat. 54". {Dr. Richardson) to the Rocky 

 Mountains. Drummond. Eagle and Red Deer Hills on the Saskatchawan, abundant. Douglas.— *' This 

 beautiful species is a striking ornament to the plains in the neighbourhood ot Carlton House, forming large- 

 patches, which are conspicuous from a distance. The specific name is a small tribute to the memory of 

 my lamented friend and companion, whose genius, had his life been spared, would have raised him to a 

 conspicuous station in his profession, and rendered him an ornament to any science in which he might 

 have chosen to direct his attention." Richards. I. c.
