far as our present knowledge of the species goes, endemic, being 
unknown elsewhere. Of these 21 are new to science. 
While some of these species will doubtless be found later in the very 
similar climatic conditions of adjacent portions of western Venezuela 
and of Ecuador, the number of local novelties found in recent collec- 
tions from Colombia is such as to suggest that the proportion of 
endemism is likely to be increased rather than diminished by further 
exploration. 
After deducting the endemic members of the genus there remain 40. 
species which occur both in Colombia and in other countries. These 
fall into several categories, as follows: ) 
1). A group of 12 common species, of wide north and south dis- 
tribution in tropical and subtropical America, extending in all instances 
from Mexico or Central America through Colombia, at least to Vene- 
zuela or Ecuador, and in most cases to Brazil, Peru, or Bolivia. These 
are E. laevigatum, ivaefolium, odoratum, morifolium, macrostemon, 
pycnocephalum, vitalbae, amygdalinum, solidaginoides, macrocephalum, 
is to say native) components in the flora of Colombia. ; 
2). The following 6 species extend from Colombia merely into 
Venezuela: E. pellium, Moritzianum, V argasianum, theaefolium, iba- 
salicinum, Stuebelit, pseudoglomeratum, obscurifolium, fastigiatum, 
gracile (doubtfully in its smoothish var. epilobioides), Dombeyanum 
azangaroense, and pichinchense. 
4). Only 5 species of Ewpatorium occurring in Colombia are also 
found on any of the Greater Antilles, namely: E. ivaefolium, odoratum, 
maicrostemon, ballotaefolium, and macrophyllum. It will be observed 
that these are all common species of wide range. All except - 
ballotaefolium (which in these larger islands of the West Indies occurs 
merely on Haiti) are found also in Mexico and Central America. 
5). Avery few species of Colombian Eupatoriums extend along the 
region of the “Spanish Main” and are also found on Margarita, 
Trinidad, or upon some of the Lesser Antilles. These are E. corym- 
bosum, iresinoides (and its var. glabrescens), inulaefolium, and ballotae- 
folium. An analogous case is presented by E. celtidifolium, 2D
