NOTES ON PHILIPPINE ORCHIDS WITH DESCRIPTIONS 
OF NEW SPECIES, II . 1 
By Oakes Ames. 
( From the Ames Botanical Laboratory, North Easton, Mass., V. 8. A.) 
In the following notes I have arranged the genera according to the 
system adopted by Pfltzer in Engler and PrantPs “Die natiirlichen 
Pflanzenfamilien.” The species included were, with few exceptions, 
collected for the Bureau of Science. In all thirty-one species are 
treated of which twenty-two are additions to my previously published 
lists of Philippine orchids.

Epipactis clausa A. A. Eaton ex Ames Orchidaceae 3 (1908) 41, pi. 38. 
In addition to the solitary specimen which constitutes the type, preserved in 
the herbarium of the Bureau of Science, I have now seen two sets of specimens 
which make possible the following emendations of the description published in 
Fascicle III of “Orchidaceae”: 
Lateral sepals broadly ovate to ovate-lanceolate, 4 mm long. Upper 
sepal similar to the lateralis and nearly equal to them, strongly reflexed 
at the tip. Petals dolabriform, 4 mm long. Labellum 2.5 to 3 mm 
long, saccate, somewhat cymbiform, obtuse, with unequal clavate hairs or 
emergences inside. 
The plants exceed 2 dm in height and arise from a creeping, fleshy rhizome. 
The leaves, about four in number, 4 cm apart, on the succulent stem, appear to 
have been dark-green when fresh, ornamented with whitish nerves. The margins 
of the leaves in dried specimens are usually strongly crenulate and in fresh
