PHILIPPINE BORAGIN ACE/E. 
By C. B. Robinson. 
( From the Botanical Section of the Biological Laboratory , Bureau of Science, 
Manila, P. I.) 
This family has an unusually small number of species endemic in 
the Philippines, only 3 of the 21 here reported being as yet unknown 
outside the Archipelago, and one of these is very closely related to a 
species of very wide distribution. No novelties are recorded, but an 
attempt has been made to settle the synonymy, so far as its Philippine 
complications are concerned : nearly all the systematic problems, however, 
involve plants of other countries. It is improbable that the present 
figures will be materially altered by future exploration. Both tropical 
and temperate elements are included, the former represented by the 
species of such genera as Cordia and Elirelia, the latter by Cynoglossum, 
Bothriospermum , and Trigonotis, in which the Philippines mark the 
extreme southeastern limit, at least for the species represented. The 
appended table enumerates the species of all the genera of the family 
which have been found in Malaysia.
