STUDIES IN AMERICAN ORCHIDS VI 
BY 
LEsLIE A. GARAY 
Dvurinc the summer of 1964, I visited Europe and 
studied the orchid material of the Lindley Herbarium 
at Kew Gardens, England, and of the Reichenbach 
Herbarium at the Natural History Museum, Vienna, 
Austria. The taxonomic decisions presented in this paper 
are the result of the research carried out at these places. 
To my colleagues Dr. Victor S. Summerhayes, Kew 
Garderis, and Dr. Karl Rechinger, Natural History Mu- 
seum, [ wish to express my sincere thanks for their kind 
cooperation during my visit. This study and the travel 
to Europe was made possible by a Grant-in-Aid for Re- 
search, GB 1858, issued by the National Science Founda- 
tion which is likewise gratefully acknowledged.
