This species appeared first at Paris in the Jardin de l'Ecole de 
Médicine, said to come from Cayenne. I obtained it from my 
late friend Emile Desvaux, in whose memory I named it. I ob- 
tained also flowers from M. Riviére, the able Curator of that 
establishment. The same plant was found in Surinam by Focke! 
(from whom I have a sketch with very dirty violet colours) and 
by Splitgerber! (from whom I obtained a flower in spirits by 
Professor Miquel!) It was also found in New Grenada by my 
friend Wagener, whose excellent dried specimen I possess. 
Finally, W. Wilson Saunders, Esq., introduced it from Brazil. 
Many of these Orchids would appear to have a very wide area. 
Those who name plants from the geographical indications will 
not feel too much pleased by such wide ranges. 
Rhizome short. Adventitious roots thick, filiform, numerous. 
Pseudobulbs near one another, the old ones ovoideo-pyriform,
