Luzon, Manila, Bureau of Science orchid house, Bur. Sci. 
78823 Quisumbing, December 29, 1929. The living specimens 
collected from Pampanga Province, on rocks on the hills back 
of Floridablanca. Flowers during December to March. 
A previous collection referable to this species, was made in 
Zambales Province, on rocks of Mount Tapolao at 2,000 feet 
altitude, November-December, 1924, Bur. Sci. UU715 Ramos and 
Edano. The flowers were described by the collectors as being 
pink and white. 
A species closely allied to Dendrobium victoriae-reginae Loher 
but differing radically in its habit and in its much larger flowers. 
The species is dedicated to Mr. S. Miyasaki, enthusiastic orchid 
grower in Manila, in whose garden the junior author has enjoyed 
every facility for the study of orchids and to whom he is under 
many obligations.

Upon critical examination of numerous living Philippine 
plants of this species it has been found that the pollen masses 
are eight in number. The species is therefore indubitably a 
member of the genus Eria as J. J. Smith has indicated, as a 
result of additional research, in Bull. Jard. Bot. Buit. Ser. 3, 8.
