Excluded Species. 



It has been impossible to ascertain upon just what material " E. 

 hcptanthiim Sch. Bip." was reported by Rusby, Bull. X. Y. Bot. 

 Gard. iv. 378 (1907) from Venezuela where "apparently collected by 

 Seemanri." From Rusby 's description, however, and from Bolivian 

 material referred by him to E. hcptanthiim it has become entirely clear 

 that he applied the name to a plant wholly distinct from the one so 

 named and described by Weddell, Chlor. And. i. 217 (1857). 



For E. azangarocnsc Sch. Bip. the following station, which might 

 be inferred to have been Venezuelan, is given b\- Weddell, Chlor. And. 

 i. 217 (1857): "Caracas: dans la Sierra-Nevada de Santa Marta!, 

 h. 2600 m. (Funck, cxsicc. no. 391)". However, from the sequence 

 of Funck's numbers mentioned elsewhere in the same work it appears 

 clear that the Sierra-Nevada de Santa Marta mentioned here was the 

 well known one in Colombia. 



EUPATORIUMS OF ECUADOR. 



The most complete previous treatments of the Ecuadorian Eupa- 

 toriums have been those of Jameson, Syn. PI. Acq. ii. 79-90 (1865), 

 and of Hieronymus in Engl. Bot. Jahrb. xxix. 5-15 (1900). In these, 

 Jameson described 1 species of Hebeclinium, which he maintained as a 

 separate genus, and 25 species of Eupatorium, while Hieronymus, 

 enumerating only such plants as were contained in the extensive col- 

 lections of the late Prof. A. Sodiro, listed 31 species and 2 varieties of 

 Eupatorium, giving many helj)ful notes regarding the older species as 

 well as diagnoses of several newly recognized members of the group. 

 In neither of these treatments was there any attempt to key the plants. 



In comparing the Eupatoriums of Ecuador with those of Colombia 

 one is struck by the considerably altered proportions of the sections. 

 Thus of the common and widely distributed Sect. Ci/lindrocephala, 

 represented in Colombia by no less than 20 species and several well 

 marked varieties, there are in Ecuador only 4 species. The two small
