 Lewis and Clarke's River. Douglas. — Four to six inches high, several stems arising- from the same root, and 

 universally bearing one flower. These flowers are old, and the corollas have fallen or are withered, the 

 fruit with the tawny pappus alone remaining.

Hab. Carltou-House Fort. Dr, Richardson, — This appears to be rare, if we may judge from the very- 

 few specimens collected. Though most allied to the preceding, it is nevertheless quite distinct. It is smaller 

 and slenderer, the leaves more remote and more attenuated below, and they and the whole plant, even the 

 floral branches, are clothed with long patent rigid leaves. Flowers yellow. Pappus tawny.

Hab. 1^. W. Coast of America. A. Menzies, Esq.-—1h\% quite accords in every essential particular with 

 authentic specimens of Chrysopsis scabra I have received from Mr. Elliott, and with others gathered at Rio 

 Brazos, in Texas, so that the species must have a very extensive range,
