STUDIES IN AMERICAN ORCHIDS IV.' 
BY 
LEsLIE A. GARAY 
In the following pages, various new species are described 
and several new combinations of taxonomic importance 
are proposed, all of which were discovered during routine 
checking of collections from the Andes. The arrange- 
ment of genera follows the phylogenetic system proposed 
by Rudolf Schlechter in Notizblat des Botanischer Gar- 
tens und Museum zu Berlin-Dahlem 9 (1926) 563-591.
