Oncidium desertorum Nash ex Withner in Amer. 
Oreh. Soc. Bull. 86: 812, 1967. 
When Dr. Withner described Oncidium desertorum, 
he designated the copy of the Plumier plate cited above 
and kept in our collection as being referable to his spe- 
cies. Untortunately, it has been overlooked until now 
that this very plate has already been given twice a new 
name. The specific name is quite inappropriate today, 
but in the 18th century the French possessions in the 
West Indies were also called the Guianas.
