I have not met ^ritll this mteresting plant in De CandoUe's Prodromua, and I rf-ould almost thmk 
it has been omitted there, unless it is his F. pMiafolinm, H latifoUun,, as stated by Miquel, 1. e. It is so 
closely alUed to Eupatorium resmosum, Poepp. et Endl. in Nov. Gen. et Sp. torn. 3. p. 04. no. 2 (of uhich I 
have seen original specimens), that at first sight it seemed to me that this Peruvian plant was ->»««= ;-"'-;<7 
of E. l^viaatum, with somewhat smaUer flower-heads ; but in examining the ach«>nia. I found the bnstlos 
of the nU "-- slender, and not so manifestly united at the base, aa is the case in our p ant, which i, 
quite the same as the original specimens gathered by Humboldt, and compared by me, in ^lUdonow s and 
Kuntli's Herbaria.

This species is most variable, not only in the degree of the pubescence, but also m the si.e and shape 
of the serratures of the leaves, which are so inconstant, that in both varieties the leaves are acutely serrate 
o epandly and obtusely toothed, or at aU entire, &om the same locality, often on the same specimen. I 
have seen this plant from Ibague, New Granada, var a (Humboldt), Caracas, var « (Mordz), Port Eoy^
