Clematis Wyethii Nutt. Journ. Acad. Phila. 7: 6 1834 



I think that this species is distinct from C. Doi/glasii. 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 Cafion, Idaho, cited in the synoptical flora 

 under C. Doiiglasii var. Scottii and in Howell's flora of the North- 

 west under C. Scottii 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. Scottii 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. 

 verticillaj-is, although he made both forms of Clematis alpina. His 

 revision of Clematis is far from good especially as to the West 

 American species. The only distmction he makes between C. 

 pseudoatragene and C. alpina is the absence or presence of stami-
