which a description of the species is given, followed by a aor 
account of its distribution and abundance. The local names 
are very convenient as assisting in the identification of the 
species, but are by no means infallible guides. It is believed, 
however, that by use of the local names, descriptions, and 
figures, it will be possible in most cases to identify the various 
species. 
In preparing this bulletin, the writers have received valuable 
assistance from many sources, but particularly from Mr. E. D. 
Merrill, Director of the Bureau of Science, and Mr. E. E. 
Schneider, wood expert of the Bureau of Forestry. The native 
names have been revised by Mr. Schneider, who is conversant 
with several Philippine dialects, and who has taken great interest 
in the proper spelling of local names of Philippine plants. The 
original drawings were made under the direction of Mr. J. K. 
Santos by Messrs. F. de la Costa, P. C. Cagampan, J. Pascasio, 
S. Calusin, and Miss Maria Pastrana. 
The writers are indebted to the Bureau of Science for the cuts 
used for figures 1, 18, 26, 27, 29, 31, 33, 36, 37, 60, and G2 pa0 
the Bureau of Education for figures 51 and 59; and to the 
Bureau of Agriculture for figure 53.
