In addition to the above material, there are about 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 southern Mindanao, and is apparently all referable to either. P. echinatus 
or to P. indicus.

As was the case with Pterocarpus echinatus Pers., only specimens with fruits 
have been here eited; most of the flowering specimens cited above probably belong 
with P. indicus. 
This species and the above yield the valuable timber known in the Philip- 
pines as narra, which is very similar to the padouk Of India. The most usual 
native names are asana, naga, and narra, and are applied indiscriminately to 
all three species here recognized; other native names are: adias (Pangasinan) ; 
nala (Abra) ; tag a (Cagayan) ; balauning (Mindoro) ; daitanag, ex Blanco.

The same native names are applied to this as to the preceding species; in 
Pampanga it is known as apalit. 
Endemic; apparently closely allied to P. papuanus F. Muell. of New Guinea. 
Pterocarpus blancoi is perhaps not specifically distinct from P. indicus ; 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 6 cm in diameter; 
as a rule the leaflets of P. blancoi are relatively narrower and more acuminate 
than are those of P. indicus, but these characters are not entirely constant. 
EXCLUDED SPECIES. 
Pterocarpus flavus Lour.: F.-Vill. Nov. App. (1880) 67. 
Probably an erroneous identification, on the part of F.-Villar, for some form 
of Pterocarpus indicus. Loureiro’s species is not a Pterocarpus, but is Pongamia 
mitis (L.) Merr. [P. glabra Vent.).
