NOTES ON PHILIPPINE ORCHIDS 
WITH DESCRIPTION OF NEW SPECIES, VII 
INCE the publication of my enumeration of the genera and 
species of Philippine orchids in the fifth fascicle of the pres- 
ent work numerous collections have been received, both from the 
Bureau of Science and from private collectors, that have con- 
tained new or noteworthy species. Although it has been impos- 
sible on account of the war to make a detailed study of the ma- 
terial that has accumulated, I have set aside from time to time, 
specimens that seem to be obviously new to the Philippine flora. 
Such of these as proved to be undescribed or worthy of attention 
are included in the following list. 
It has become apparent thatnumerous genera of Philippine or- 
chids need to be thoroughly reworked if we are to profit from the 
material that has been referred, often tentatively, to various spe- 
cies that were originally described from a limited number ofspeci- 
mens or from a single plant. This is true especially of Bulbophyl- 
lum, Dendrobium, Dendrochilum, Eria, Liparis and Malaxis. 
In these genera there are many species that may be too laxly de- 
fined or too closely circumscribed. Critical work in the field may 
be necessary, together with a careful study of Malayan types, to 
solve some of the problems suggested by Malaxis. This genus 
constitutes a very puzzling group which, when studied from her- 
barium material, presents anexasperating number of perplexities. 
Dendrochilum needs to be examined very thoroughly from the 
point of view of distribution. It would seem that many species 
of the section Acoridium are localized or restricted in their range 
to the higher altitudes of isolated mountains. Here we have an 
opportunity for investigations that may conclusively prove that
