NEW OR NOTEWORTHY PHILIPPINE PLANTS, VI. 
By Elmku D. Mkrkill. 
{From the Botanical Section of the Tiiological Labojatory, Bureau of ^Vjcjk'c, 
Manila, P. J,) 
During tlie pa^st five years approximately 1,000 new species have been 
described from tlie Pliilipj^inos, the material on whicli tliey were based 
being for most part of recent collection. In spite of the large amount 
of work accomplished, the nmnber of new forms that are constantly 
being found is surprising, and our herbarium to-day contains several 
Iiundrod undescribed species, wliile additional ones are found in nearly 
every collection that is made, especially in those from previously unex- 
plored regions. 
In the present paper reprc?L'ntati\es of six genera previously not 
known from the Archipehigo are recorded. Eight species, first described 
from extra-Philippine material, are also here listed for the first tiiue 
from the Philippines, and about sixty species are described as new. One 
new genus, Sagitti petal um, of the Jxhizophoraccae, is described.
