been reported from a wild specimen. It was described 
about one hundred years ago from greenhouse material. 
Lindley received flowers of the plant, from which he de- 
scribed the species, and soon afterward he illustrated it in 
the Botanical Register. Lindley’s material, which was in 
cultivation in England, was said to have originated in 
Brazil. Recently we have received three different collec- 
tions of this species from Mexico which perhaps indicates 
that the garden material on which the species was orig- 
inally based came from Mexico rather than from Brazil. 
It is interesting to note that all of the species of the sub- 
genus Clowesia are Central American,—a fact which 
also points to a Mexican rather than a Brazilian origin 
of this species.
