KIPATORIUMS OF VENEZIELA. 331 



III. KEYED RECENSIONS OF THE EUPATORIUMS OF 

 VENEZUELA AND ECUADOR. 



In the course of work primarily directed toward a revision of the 

 Colombian Eupatoriums it was found needful to devote considerable 

 attention to the identical or closely related species of Venezuela and 

 Ecuador, and finally it has seemed desirable to list and key all the 

 species of this genus known from those countries. As it appears 

 likely that the matter thus assembled from very scattered sources 

 will be found useful pending a monographic treatment of the whole 

 group which cannot be completed for some jears to come, it is here 

 put on record. 



EUPATORIUMS OF VENEZUELA. 



Since Kunth, working upon the specimens secured by Humboldt 

 & Bonpland, enumerated in 1820 five species of Eupatorium from 

 Venezuela, there appears to have been no attempt to bring together, 

 catalogue, key out, or otherwise to give any separate treatment for 

 the Venezuelan members of this large genus. Although similar to 

 Colombia in territorial extent and indeed comparable in its diversity 

 of soil and variety of climatic conditions Venezuela is to our present 

 knowledge much less rich in its flora, and in the case of Eupatorium 

 has less than half as many species. 



This difference, however, is probably more apparent than real, 

 and it is to be remembered that of all the South American countries 

 Venezuela has to date received the least botanical exploration. Indeed 

 except for a few scattered and essentially coastal points which have 

 been frequently visited, such as those around Caracas and La Guaira, 

 Cumana and Carupano, Cumarebo and Porto Cabello, the only regions 

 which appear to have had any serious botanical attention since the 

 hurried journey of Humboldt and Bonpland more than a century ago 

 have been the uplands of Merida, visited by Moritz, Pittier, Jahn, 

 Haman, and others, especially the region of Tovar, for some months 

 the base of the indefatigable collector Fendler, the Paraguana Penin- 

 sula, recently explored for its forestry resources by Curran & Haman, 

 the islands of Margarita and Coche, diligently explored and carefully
