NEW ORCHIDS FROM CEYLON 
BY 
Don M. A. JAYAWEERA 
THE present paper is the result of a detailed field inves- 
tigation of the orchids growing in the Ceylon jungles, 
undertaken during 1958-60. Nine new species are pro- 
posed, six of them belonging to the genus Oberonia and 
one each to the genera Cirrhopetalum, Saccolabium and 
Taeniophyllum. The type specimens are deposited in the 
Herbarium Peradeniya. These new species have been 
checked with the extensive collections of the Ames Or- 
chid Herbarium, and they form a part of my forthcom- 
ing treatment of the Orchids of Ceylon. 
I wish to express my sincere gratitude and apprecia- 
tion to Mr. Leslie A. Garay of the Oakes Ames Orchid 
Herbarium for his valuable suggestions and for render- 
ing the descriptions into Latin.
