Epidendrum apaganum Mansfeld in Notizbl. Bot. 
Gart. & Mus. Berl. 10 (1928) 240. 
The features which appear to distinguish J”. apaganum 
from its allies are the robust growth, the oval-oblong 
emarginate leaves and certain features of the lamina of 
the lip notably the irregularly dentate outer sides of the 
lateral lobes and the entire obtuse terminal lobe. 
The leaf-form shown by the type of 4’. apaganum co- 
incides well with that illustrated for 27. difforme in Jac- 
quin Select. Stirp. Am. t. 186. Furthermore, a Peruvian 
collection (Alwg 0.5 trom the Department of Loreto) 
has an exactly similar growth and even larger leaves than 
those of #7. apaganum as well as a lip with precisely the 
measurements of that species; yet it has the lobing of 
the lip with the subentire sides and the transverse emar- 
ginate mid-lobe of typical 7. difforme. Frequently the 
outer sides of the lateral lobes of J’. difforme are some- 
what dentate and the mid-lobe of this polymorphic spe- 
cies is sometimes simple and obtuse as shown in the 
instance of £7. apaganum. 
Considering the almost inconceivable variability of 2. 
difforme, it appears wise not to recognize another ques- 
tionable segregate in this immediate alliance. 
For the full synonymy of J”. difforme, reference should 
be made to Botanical Museum Leaflets Harvard Uni- 
versity 2 (1984) 50-55.
