RAFFLESIACEAE—POLYGONACEAE 135 
Master’s: description was based, was from Ilocos Norte Province, 
Luzon, Blanco’s specimens being from Agoo, Union Province, 
Luzon. The species is known only from the Ilocano provinces, 
where it has been collected several times. 
Illustrative specimen from Union Province, Luzon, December, 
1916, here known as banguist (Merrill: Species Blancoanae 
No. 1049). 
Aristolochia subsagittata Blanco FI. Filip. (1837) 283 (sp. nov.); ed. 2 
4 (1845) 197; ed. 3, 1 (1877) 350, t. 104=ARISTOLOCHIA TAGALA 
Cham. : 
Aristolochia indica Blanco op. cit. 282; 197; 349, non Linn.=ARISTO- 
.., LOCHIA TAGALA Cham. 
Aristolochia tagala Cham. is the only indigenous species of 
the genus-found near Manila, and Blanco’s descriptions of both 
Aristolochia subsagittata and A. indica apply to it. The latter, 
from Blanco’s description, has nothing to do with the Linnean 
species, although Fernandez-Villar considered that he correctly 
intrepreted Aristolochia indica Linn. Aristolochia tagala Cham. 
presents a great deal of variation in its vegetative characters, in 
the shape and size of its leaves, the length of its petioles, etc. 
Illustrative specimen from between Manila and Pasig, Rizal 
Province, Luzon, March, 1911 (Merrill: Species Blancoanae 
No. 289).

‘There is no doubt as to the correctness of Fernandez-Villar’s 
reduction of Blanco’s species. It is common and widely dis- 
tributed in the Philippines at low and medium altitudes, but
