NEW OR NOTEWORTHY PHILIPPINE PLANTS, XVII 
By ELMER D, MERRILL 
Director and Botanist, Bureau of Science, Manila 
The last paper of this series was published in 1920.1 In the 
present paper one hundred six new species are described 
from various parts of the Philippines, while a redescription of 
Ficus argentea Blanco is included. This species, previously 
known only from Blanco’s imperfect description, on receipt of 
material agreeing with his description in all essentials proves 
to be a valid one. Polychroa Loureiro is accepted as the proper 
generic name for the group long known as Pellionia Gaudichaud, 
while the few Philippine forms formerly placed in Polytrema 
are now transferred to Hallieracantha. Three genera, Pyrena- 
ria, Pleiocarpidia, and Cowiea, the latter a recently described 
genus previously known by a single species in British North 
Borneo, are recorded from the Philippines for the first time. 
A few notes on nomenclature are included, which involve some 
changes in specific names.
