CLEMATIS Wyetui Nutt. Journ. Acad. Phila. '7: 6 1834 
I think that this species is distinct from C. Doug/asit Hook., the 
leaves being never twice pinnately divided, having much broader 
segments and never being falsely verticillate as in that species. The 
specimens from Beaver Cajion, Idaho, cited in the synoptical flora 
under C. Douglasii var. Scottii and in Howell’s flora of the North- 
west under C. Scotti belongs undoubtedly here. A broad-leaved 
C. Wyethii and a narrow-leaved C. Scottii resemble each other very 
much and can be distinguished only by the flower, which in the 
former is campanulate with oblong-lanceolate sepals and in the 
latter rounded urn-shaped with broadly ovate sepals. C. Wyethii 
is common in Montana and northern Idaho. It is represented by 
the specimens cited under C. Scoftii and some under C. Douglasii 
in my catalogue of the flora of Montana.

Dr. Gray adopted the name occidentalis as a varietal name for 
another species, and cites Homeman’s plant as a synonym. It is 
very evident that the latter is the common plant of the Columbia 
Valley with simply ternate leaves and subentire leaflets, for Home- 
man expressedly describes them as entire. Dr. Kuntze was so 
far right that he placed Atragene occidentalis Homeman with A. 
verticillaris, although he made both forms of Clematis alpina. His 
revision of C/ematis is far from good especially as to the West 
American species. The only distinction he makes between ¢. 
Pseudoatragene and C. alpina is the absence or presence of stami-
