A flower which was recently loaned to me from the 
type of the Colombian Epidendrum ibaguense and a 
photograph of that species from the Muséum d’ Histoire 
Naturelle in Paris show that it is synonymous with /. 
radicans as represented by a photograph of the type spec- 
imen from the British Museum of Natural History in 
London, and by numerous specimens in the Ames Her- 
barium from Mexico and Central America. The only no- 
table difference between the concepts is that . radicans 
generally has long whitish roots proceeding from the stem 
(commonly opposite the leaf-joints), whereas in L’. ibag- 
uense no such roots appear. Furthermore, some specimens 
of EH. radicans are apparently destitute of these roots. 
It appears, moreover, that many examples of 2. radicans 
have petals which are broader than the sepals, rather than 
narrower, but this character is variable and not typical 
of the species. Both concepts have orange to vermilion 
flowers. For the synonymy of J. radicans, see Ames, 
Hubbard & Schweinfurth The Genus E/pidendrum in the 
United States and Middle America (1986) 162. 
Judging from a photograph of the type and co-type 
of Mpidendrum decipiens in the Ames Herbarium, this 
concept also cannot reasonably be separated from £7. 
ibaguense. This South American species also has orange 
flowers.
