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

SCHEFFLERA Forst. 
1. S. caudata (Vid.) Merr. & Rolfe in Philip. Journ. Sci. 3 (1908) Bot. 118. 
Stream depressions in the pine region below 1,200 m, 0. M. Z. 16331. 
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. Rather widely distributed in the Philippines at medium altitudes; 
endemic.
