SCHEDULAE ORCHIDIANAE 
No. 10 
New or Noteworthy Orchids 
BY 
OAKES AMES and CHARLES SCHWEINFURTH 
TN the following pages sixty-nine new species and three 
A new varieties are proposed, and the results of recent 
studies of tropical orchids are set forth. The new species, 
with the exception of the Cuban Lepanthes fractiflexa, are 
natives of Central America. 
The sequence of genera conforms in large measure to 
the arrangement adopted by Pfitzer in Engler and Prantl’s 
“Die nattirlichen Pflanzenfamilien.” 
Unless otherwise specified, the type specimens have been 
deposited in the herbarium of the senior author.
