This will probably prove a genus distinct from Wihorgia, 

 with which it somewhat agrees in habit; but it differs in the 

 many-leaved involucre, in the linear, or almost setaceous and 

 hispid scales of the receptacle, the narrow bidentate corollas 

 of the ray, and the pappus composed simply of short indis- 

 tinct hairs.

This has the closest affinity with U. anemonifolia of Humb. 

 and Kunth, A^ov. Gen. v. 4. t. 402, nor do I know that it 

 can properly be separated from it. I have done so on 

 account of the leaves, which are simply tripartite and lacini- 

 ated in the latter; in our plant really ternate, the divisions 

 being stalked, and those again much divided, and deeply 

 laciniated.
