recognition as new to science, while others show notable rediscoveries 

 of plants not secured for many -decades. 



As has been the case in the preparation of several former papers 

 relating to the Eupatoriian tribe, much valued aid has been received 

 from the New York Botanical Garden, the United States National 

 Herbarium, and the Field Museum of Natural History, all of these 

 establishments having lent for examination highly interesting material, 

 which has formed the basis of many of the observations here recorded. 



In elaborating the Peruvian species much aid has been derived from 

 material borrowed from the Royal Gardens at Kew and from a con- 

 siderable suite of specimens collected by Dr. A. Weberbauer and lent 

 some years ago from the Royal Botanical Museum in Berlin for study 

 and identification. 



Prof. H. Pittier has kindly called to the writer's attention some 

 geographical errors in the paper on the Venezuelan Eupatoriums. 

 Among these are the employment of several obsolete and now sup- 

 'planted place-names, and several orthographical slips which, while 

 regretted, are happily not of a kind likely to cause serious error or 

 misunderstanding. More annoying, however, in this respect was the 

 writer's not unnatural but entirely erroneous identification of " Colonia 

 Tovar" — a place frequently mentioned upon Fendler's labels — 

 with the town of Tovar in the state of Merida. In consequence, 

 attention is here particularly directed to the fact that Colonia Tovar, 

 the base of much of Fendler's Venezuelan work, is a small town not 

 very distant from Caracas and situated in the mountains somewhat 

 back from the coast in the northern part of the state of Aragua. This 

 Tovar was unfortunately not recorded on the maps consulted during 

 the preparation of the earlier paper. 



A few notes, diagnoses, and transfers are here published concerning 

 other Compositac which, mostly on account of habital similarity, have 

 been submitted for identification in connection with these studies on 

 the Eupatoriums. 



The abbreviations employed in the present publicatiorr to indicate 

 the different botanical establishments are the same as in former 

 papers, those of most frequent occurrence being as follows: Gr. for

 Natural History, Chicago; K., the herbarium of the Royal Botanical
