cordate lamina about 5-6 mm. long and broad; mid-lobe 
shallowly trilobulate to undulate-simple, apiculate; disc 
bicallose at base with the center marked by three more 
or less thickened nerves. Column arcuate, adnate to the 
lip foritsentire length; clinandrium minutely denticulate. 
Var. simulacrum approaches var. Storku most closely, 
but is separable by its almost orbicular and smaller lip. 
It differs from exceptionally small-flowered specimens of 
the typical form of the species in having the mid-lobe of 
the lip little broader than long. 
KPIDENDRUM PANICULATUM ALLIANCE 
The members forming this alliance, geographically 
extending over a much larger area than the two alliances 
already discussed, show great variation in both vegetative 
and floral characters. These variations, however, do not 
seem to indicate the presence of several different species, 
indeed they do not seem to exhibit sufficiently stable 
characters through which to segregate varieties. It appears 
to us, therefore, after careful study of an abundance of 
material, that a single polymorphic species is represented. 
Closely allied to this polymorphic species, but capable of 
clear separation, are several other species. The earliest 
specific name applied toa member of this alliance is Zpi- 
dendrum panitculatum Ruiz & Pav. and this name, we 
believe, should be adopted for the polymorphic species. 
Epidendrum paniculatumwas described by Ruiz and 
Pavon as follows: “‘E. foliis oblongo-lanceolatis, floribus 
paniculatis, nectaril lacinia intermedia bifida; lacinulis 
extrorsum flexis.’* While this description is too indefinite 
to place the plant with certainty, it appears capable of 
application to only six species (including J7. paniculatim ) 
which have been reported from Peru, the type locality of 
the species, all of which belong to this general alliance.
