has partly been determined by exclusion. The region from which 
Blanco received his material is thoroughly well known bo- 
tanically; and Dalbergia minahassae Koord., which still grows 
in the same general region, is the only species in the entire area, 
and for that matter is the only species of Dalbergia known from 
the Philippines, that conforms at all with Blanco’s description. 
‘ PTEROCARPUS Linnaeus 
Pterocarpus pallidus Blanco Fl. Filip. (1837) 560 (sp. nov.); ed. 2 (1845) 
391; ed. 3, 2 (1879) 355, t. 205=PTEROCARPUS INDICUS Willd. 
This species is very widely distributed in the Philippines; it 
is one of the most valuable timber trees in the Archipelago. 
Illustrative specimen from Taytay, Palawan, May 1913 (Mer- 
rill: Species Blancoanae No. 575). 
Pterocarpus santalinus Blanco Fl. Filip. (1837) 561; ed. 2 (1845) 392; ed. 
8, 2 (1879) 356, non Linn, f.=PTEROCARPUS BLANCO! Merr. 
Pterocarpus santalinus Blanco, as I have interpreted it, is a 
form very closely allied to Pterocarpus indicus Willd., dis- 
tinguishable only by its larger fruits, which are from 6 to 8 cm 
in diameter; it possibly should be merged in Pterocarpus indicus 
Willd. and, again, should be critically compared with Pterocarpus 
papuanus F.-Muell. Fernandez-Villar considered that Blanco 
correctly interpreted Pterocarpus santalinus Linn. f., but Blan- 
co’s description does not conform to the characters of this spe- 
cies, which, moreover, does not extend to the Philippines. 
Illustrative specimen from Bauang, Union Province, Luzon, 
November, 1916 (Merrill: Species Blancoanae No. 995). 
PONGAMIA Ventenant 
Galedupa maculata Blanco Fl. Filip. (1837) 559 (sp. nov.); ed. 2 (1845) 
390; ed. 3, 2 (1879) 353, t 417=PONGAMIA PINNATA (Linn.) 
Merr. Interpret. Herb. Amb. (1917) 271 (P. glabra Vent.). 
This species is common and widely distributed along the 
seashore throughout the Philippines and was correctly reduced 
by Fernandez-Villar to Pongamia glabra Vent., which is a syno- 
nym of Pongamia pinnata (Linn.) Merr. 
Illustrative specimen from Looc, Batangas Province, Luzon, 
April, 1915 (Merrill: Species Blancoanae No. 958).

Pterocarpus frutescens Blanco Fl. Filip. (1837) 562 (sp. nov.); ed. 2
