bing, February 7, 1931. The living plants were collected from 
Baguio, Benguet Subprovince by Mr. S. Miyasaki, an orchid 
grower, and are now in cultivation in his gardens. The first 
Philippine specimen was collected by A. D. E. Elmer 6517 (type 
of G. philippinensis Ames) in Baguio, June 28, 1904. The spe¬ 
cies has also been reported from Sikkim and the Khasia Hills, 
Java, Sumatra, and Assam. 
After a careful study of this Philippine material, it has been 
found necessary to reduce G. philippinensis Ames to synonymy 
as the characters relied on for specific distinction have proved to 
be unreliable.
