ARALIACEiE. 
ARALIA Linn. 
1. A. hypoleuca Presl Epim. Bot. (1851) 250. 
In the mossy forest above 2,250 m, G. M. Z. 18135, also in gorges in the pine 
region at about 2,000 m, G. M. Z. 18112. 
Higher mountains of Luzon. Forbes and Hemsley reduce this to A. spinosa

The specimen has very young flowers, and like most of our material from the 
Benguet region, differs slightly from the type; I have, however, detected no specific 
differences. Bather widely distributed in the Philippines at medium altitudes; 
endemic.
