probable that they are identical and possible tliat they both will have 
to be referred to D. pilosus. This is partionlarly likely in view of the 
extreme variability in size, shape, and texture of the leaves at different 
ages in species of this genus. It will, however, require careful observation 
in the field before any such reduction can safelj be made.

3. Dipterocarpus sp. aff. D. iurhinato Gaertn, f. Phite XXXIX. 
A form with fruit whicli is distinctly obconical or top-shaped. Leaves 
and buds glabrous or nearly so, resembling material of D. tnrhinaliis var. 
andamankiis King. Our material is all fragmentary, the fruit having 
been collected on the ground under the trees. Yldal, Sinopsis, Atlas 
(1883) XV, i. IJf, f. c. represents a fruit which he calls B. turhinatiis 
and which is said to have been brought from the Island of Fanay. The 
fruit figured by Vidal is apparently not so top-shaped as in the specimens 
cited below. 
Some of the material from the Malay Peninsula in the herbarium at 
Kew under the name of D. turhinatus has fruit very much like the 
following :

Tliis species seems to be fairly common in dense forests on low riilges in some 
parts of Tayabas.
