REVISION OP PHILIPPINE COMBRETAC1MS. 047 



This species, although remarkably uniform in vegetative and lloral characters, 

 shows some variation in its fruits, which have from two to four wings, one of the 

 Cuming specimens showing 2- and 3-winged fruits on the same plant. Prom an 

 examination of cotypes of both of Presl's species, before me, I am unable to 

 distinguish them, and hence have included both under the first specific name. In 

 my first consideration of Philippine Terminalia* both of the species described by 

 Presl were misinterpreted, as neither the original descriptions of the species, nor 

 cotype material was then available in Manila. T. polyantha was reduced to 

 T. catappa, to which it is not at all^closely allied, while the specimen referred to 

 T. parviflora does not represent that species. Later 3 T. polyantha was referred 

 by me with doubt to T. comintana, which it resembles strongly in its inflorescence, 

 and closely in its leaves, but which has entirely difiVrent fruits. 



Endemic. 



11. Terminalia quadrialata Merr. in Philip. Journ. Sci. 4 (1909) Bot. 301. 



This species is represented by a number of specimens from southern Luzon, 

 Masbate, and Samar, but the flowers are as yet unknown. It is apparently 

 universally known as Toog in the regions in which it is found.
