After a careful comparison of these concepts which are 
both represented in the Ames Herbarium by records of 
the type collections, it appears that they are conspecific. 
Indeed the only discrepancies seem to be that in J. ven- 
tricosum (represented by a pen drawing with floral analy- 
sis) the leaves are narrower than those of 17. pachygastrium 
(exemplified by a photograph of the type and by a frag- 
ment of the type collection) and the calli at the base of 
the hp in £2. ventricosum are shown as subglobose, while 
those of 7. pachygastrium are described as rather long.

Bifrenaria Lindley 
Lindleyella Schlechter 
Lindleyella, a genus founded by Schlechter (Die Oreh- 
ideen (1914) 414), isa segregate from Bifrenaria Lindl., 
based on B. aurantiaca Lindl. The reason for separating 
this generic concept from the variable genus Bifrenaria 
was claimed to be the presence of an elongate claw to the 
lip of this species, and the fact that the lateral lobes were 
abrupt and separated by a conspicuous callus. 
It is a fact, however, that at least one species of true 
Bifrenaria (B. sabulosa Rodr.) has an equally elongate
