specimen, would seem to be inseparable from 5. parvula. 
S. Bradei Schltr. was originally described as a close ally of 
5. rhodochila. From a sketch of the type, and from studies of 
flowers taken from the type, I have been unable to discover 
any reliable character for the differentiation of S. Bradei 
from S. parvula. 
The prevailing color of the flowers of Stelis parvula 
Lindl. is greenish yellow with the labellum sometimes pur¬ 
plish. Rarely the flowers are suffused with purple through¬ 
out. These color differences do not seem to be correlated with 
structural differences and for purposes of classification may 
be wisely ignored.
