Epidendrum melinoacron is typified by Weberbauer 
6300, which collection was, as stated above, formerly 
identified as 7. anthoceros Lind. & Reichb.f. Like the 
latter concept, it has the rounded lateral lobes of the lip 
with denticulate margins and it resembles 2. Pavonia- 
num in having dorsally carinate sepals and centrally thick- 
ened lateral lobes of lip—characters which are not men- 
tioned in either Z’. cornutum or in Ef. anthoceros. 
Considering the evident variability of 2’. cornutum as 
interpreted by Lindley and the apparently obscure char- 
acters of the lateral lobes of the lip in the allied forms, 
it seems best to treat these concepts as variants of one 
polymorphic species.

It appears, from a careful study of the description of 
EI. saccharatum from British Guiana, that this concept is 
referable to the extremely variable 2’. crassilabium which 
is more generally known as 2. variegatum. Slight dis- 
crepancies occur in the elongate creeping rhizome, the 
somewhat broader leaves and the more elongate pedicel- 
late ovaries attributed to 27. saccharatum.
