various shades of pink, and rarely maroon or white forms 
occur. 
Epidendrum vanthinum Lindl. with yellow flowers is 
a species very closely allied to 2. brachyphyllum, but it 
appears to have a dissimilar less distinctly lobed callus 
on the lip. 
Epidendrum catillus Reichenbach filius & Warsce- 
wicz in Bonpl. 2 (1854) 112. 
Epidendrum vinosum Schlechter in Fedde Repert.

The Colombian EHpidendrum catillus, which was de- 
scribed from a peduncled inflorescence only, is represent- 
ed in the Ames Herbarium by several drawings (with 
analyses of the lip) from the Reichenbach Herbarium in 
Vienna. The mid-lobe of the lip is shown as subquadrate- 
obovate and apiculate as described; but the basal cren- 
ulate callus is depicted as scarcely exceeding the base of 
the mid-lobe whereas it is described as extending from 
the base to the apex of the mid-lobe. 
In the Peruvian /. vinosum, of which I have seen sev- 
eral examples, the mid-lobe of the lip is ovate-lanceolate 
or ‘‘oblong-linguiform’’ (as described) and more or less 
abruptly acute. In these examples the crenulate callus 
is produced to about the middle of the mid-lobe or slight- 
ly above, whereas it is described and illustrated as scarcely 
produced above the base of the mid-lobe. In an Ecua- 
dorian collection reasonably referred to 2. catillus, how- 
ever, the mid-lobe is rather subquadrate with a truncate 
and apiculate apex and thus appears to be of a form in- 
termediate between LF. catillus and EH. vinosum. 
Asis characteristic of this group of Epidendrums, there 
is considerable variation in the exact formation of the de- 
tails of the lip. Accordingly, it seems advisable to include 
FE. vinosum in the concept &. catillus.
