A NEW ONCIDIUM FROM HONDURAS 
BY 
OAKES AMES 
From J. B. Edwards there has been received a spe- 
cies of Oncidium which appears to be new. It is related 
to O. glossomystax Reichb.f. and O. Titania Schltr. , but 
differs from them in having the dise of the labellum, in 
front of the callus, quite free from appendages. ‘The 
closest ally is undoubtedly O. gnomus Krinzl., but that 
species also differs in having a more complicated crest on 
the labellum. It is probable that the crest varies consid- 
erably and is not a reliable guide to specific distinction, 
but until more material has been examined it would be 
questionable procedure to merge the Honduran plant 
with O. gnomus. It is a charming species and with O. 
gnomus and O. Titania enjoys the distinction of being 
one of the smallest species of the genus vet known.
