sion, all uniting centrally, lying nearly Hat upon the capsule, somewhat 
star-like, the arms either radiating equally or more to one side. 
A tree attaining a height of 10.5 m, with a trunk 22.5, cm in diameter,

alternate, borne on petioles 4-7 mm long, the lamina submembranaceous, 
entire or slightly wavy upon the margins, elliptic or oblong, 10-16 cm 
long, 4-6 cm wide, acute at the base, at the apex contracted into an 
acumen about 2 cm long, often apiculate, dull green on the upper sur- 
face, glaucous on the under surface, with 5-7 primary lateral veins on 
each side of the midrib ; stipules lanceolate, 4 mm long, caducous. 
Type collected at Santa Cruz, District of Davao, Mindanao, by E. S. Wil-

This genus has not hitherto been reported from the Philippines. Fragments 
from Williams 1121 were sent for comparison with the type to Dr. B. Hayata 
of the Imperial Botanical Gardens, Tokyo, and lie finds that while the Philippine 
plant has rather larger flowers, with slightly prominent ridges on the wall of the 
ovary, and leaves not exactly identical in outline with the Formosan material, 
the differences are not of sufficient importance to justify specific segregation.
