The living specimens were collected at Surigao, Surigao Prov¬ 
ince, Mindanao, by the botanical collectors, Messrs. Maximo 
Ramos and Pascual Convocar. 
Among Philippine orchids, this species differs from Bulbo- 
phyllum Loherianum (Kranzl.) Ames in the much larger 
flowers and dissimilar lateral sepals and from B. zamboangense 
Ames in the awnless dorsal sepal and petals. It is vegetatively 
very similar to B. medusae Reichb. f.
