This will probably prove a genus distinct from Wiborgia, 
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. :

foliolis tripartitis laciniatis in petiolulum attenuatis, flos- 
culis disci et radii circiter 5.

This has the closest affinity with U. anemonifolia of Humb. 
and Kunth, Nov. 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.
