Epidendrum dilochioides is closely allied to HE. estrel- 
lense Ames, a Costa Rican species from which it may be 
distinguished as follows: 
Epidendrum dilochioides 
Lip not cordate at the base. 
Floral bracts 15-30 mm. long. 
Leaves obtuse. 
Lamina of the lip with two cari- 
nae which extend only to the 
middle. 
Epidendrum estrellense 
Lip cordate at the base. 
Floral bracts about 12 mm.long. 
Leaves acute. 
Lamina of the lip tricarinate, the 
middle carina extending to the 
apex. 
The mid-lobe of the lip in both species is very incon- 
spicuous. 
The specific name of Mpidendrum dilochioides is sug- 
gested by the resemblance of the floral bracts to those of 
some species of Dilochia.
