STUDIES IN EPIDENDRUM 
BY 
Oakes Ames, F.TRacy Husparp 
AND CHARLES SCHWEINFURTH 
DuRING our studies of the North American species 
of Kpidendrum, we have examined the material pre- 
served in many of the large herbaria and have found sev- 
eral species and varieties which we find are undescribed. 
There are a few changes in rank or generic conception ren- 
dering new combinations necessary. Furthermore,— due 
to the revision in the rules of nomenclature accepted at 
the Congress held in 1980, at Cambridge, England,— the 
specific names of a number of species should be changed 
because of earlier use. 
The purpose of this paper is to publish descriptions 
of the specimens we believe to be new and to make the 
necessary nomenclatorial changes. 
Epidendrum adenocarpon La Llave & Lew.var. 
Rosei Ames, Hubbard & Schweinfurth var. nov. 
A typo labelli lobis lateralibus ovato-triangularibus 
abbreviatis differt. 
Lateral lobes of the lip abbreviated, obliquely tri- 
angular-ovate, rounded or subacute at the apex, anterior 
margin of the free portion about 1.6 mm. long, when 
expanded little exceeding the width of the mid-lobe. 
The variety differs from the typical form chiefly in 
the shorter and differently shaped lateral lobes of the lip
