INTRODUCTION. 
The present article lias been prepared as material and data became 
available, as was the case ivith the previous papers published under the 
above title. ^ Our receipts of Philippine botanical material from various 
sources a])pro.ximate 5,000 numbers annually and the percentage of nn- 
described species and interesting forms is very large, as is to be exjiected 
in a region botanically so little known as is this Archipelago. In making 
the preliminary identifications, immediately after the receipt of the 
material in the herbarium, many of the interesting forms are detected 
and described, but in this paper, as in the preceding ones of the series, 
only a portion of these foi-ms are considered. Practically no work in some 
groups can at present lie done in Manila, owing to a lack of literature; 
in certain ones, all material is submitted to specialists for identification 
and report. Frequently, specific identifications can not be made at once, 
because of a lack of complete material, so that several hundred sheets, 
apparently representing undescribed species, remain in the herbarium of 
this Bureau and for one reason or another these will need to be considered 
at a later date. In general, it is not considered good policy to describe 
species based on a single siiecimen and many of the apparently nn- 
described plants at present in our herliarinm have no corresponding- 
duplicate material.
