370 The Philippine Journal of Science 1931 
With the increasing interest that is being taken in the or¬ 
chids of the Philippines by owners of gardens in the vicinity of 
Manila, there has developed a pressing need for critical studies 
of the horticultural forms which are commanding attention. 
The time has come when the study of living material should be 
undertaken more and more intensively, not only to solve horti¬ 
cultural problems, but to verify and amplify the results of the 
investigations through which our present knowledge of the 
Philippine orchid flora has been gained. 
The types of the new species and varieties herein described 
have been deposited in the herbarium of the Bureau of Science 
and are represented by isotypes in the herbarium of Oakes 
Ames. Available isotypes will be distributed to American and 
European herbaria. All of our descriptions in the following 
pages have been prepared from living material with the excep¬ 
tion of the one devoted to Bulbophyllum ornatissimum. All 
illustrations are by Mr. Jose M. Salazar, draftsman of the divi¬ 
sion of botany, Bureau of Science. The color terms used are 
mostly from Ridgway’s Color Standards and Color Nomencla¬ 
ture (1912). 
The present paper contains the descriptions of four species 
and one variety that appear to be new to science. Several 
previously described species are also included, together with 
notes and descriptions. Haemaria is included as a genus new 
to the Philippines. 
The authors are under obligation to Dr. William H. Brown, 
Director of the Bureau of Science, who has given enthusiastic 
support and encouragement to the study of Philippine orchids.
