PHILIPPINE BORAGINACE^. 



By C. B. Robinson. 

 {From the Botanical Section of the Biological Laboratory, Bureau of Science, 



Manila, P. I.) 



This family lias 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 Ehreiia, the latter by Cynoglossum, 

 Bothriospcrmitm, 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.
