NEW OR NOTEWORTHY PHILIPPINE PLANTS, VI. 
By Elmer D. Merrill. 
( From the Botanical Section of the Biological Laboratory, Bureau of Science, 
Manila, P. I.) 
During the past five years approximately 1,000 new species have been 
described from the Philippines, the material on which they were based 
being for most part of recent collection. In spite of the large amount 
of work accomplished, the number of new forms that are constantly 
being found is surprising, and our herbarium to-day contains several 
hundred undescribed species, while additional ones are found in nearly 
every collection that is made, especially in those from previously unex- 
plored regions. 
In the present paper representatives of six genera previously not 
known from the Archipelago are recorded. Eight species, first described 
from extra-Philippine material, are also here listed for the first time 
from the Philippines, and about sixty species are described as new. One 
new genus, Sagit li/pet alum, of the Rhizophoraceae, is described.
