In addition to tlio above material, tlieie are alx)ut 40 additional sheets, 

 consisting of leaf specimens only, in the herbarium of the Bureau, which are 

 not cited here. This material comes from many different localities from northern 

 Luzon to s'outhern Mindanao, and is apparently all referable to either P. echinatus 

 or to P. hulicus.

As was the case with Pterocarpus echinaius Pers., only specimens with fruits 

 have been here cited; most of the lloworing specimens cited above probably belong 

 with P. indicus. 



This species and the above j^ield the valuable timber known in the Philip- 

 pines as 7ian-a, which is very similar to the padouk of India. The most usual 

 native names are asana, naga, and narra, and ai'e applied indiscriminately to 

 all three species here recognized; other native names are: odias (Pangasinan) ; 

 nala (Abra) ; taga (Cagayan) ; halauning (Mindoro) ; daitanag, ex Blanco.

The same native names are applied to this as to the preceding species; in 

 Panipanga it is known as apalit. 



Endemic; apparently closely allied lo P. papuanus F. Muell. of New Guinea. 



Pterocarpus hlancoi is perhaps not specifically distinct from P. iridicus; it is 

 characterized by its much larger pods (6 to 8 cm in diameter), while P. indicus, 

 at least the typical form, usually has pods 5 cm or less in diameter; some 

 forms cited above under P. indicus have at least some pods G cm in diameter; 

 as a rule the leaflets of P. hlancoi are relatively narrower and more acuminate 

 than are those of P. indicus, but these characters are not entirely constant.

Probably an erroncrms identification, on the part of F.-Villar, for .sonic form 

 of Pterocarpus indicus. Loureiro's species is not a Pterocarpus, but is Pongamia 

 milts (L.) Mcrr. (P. ghihra Vent.).
