Described by Dyer from a sterile specimen collected by Teysmanii in Bangka and 
distributed under the name of Hopea fagifolia Miq. 
Leaves ovate-oblong, acuminate, pale-brownish beneath. Stipules 
lanceolate, slightly falcate, 2 to 2.5 cm long, 5 to 8 mm broad, caducous ; 
secondary nerves 10 to 14 pairs, tertiary nerves parallel and not very 
prominent. Leaf-blade 12 to 15 cm long, 4 to 6 cm wide ; petiole 1 to 1.5 
cm long. Differs from 8. polysperma in the larger stipules and in having 
the midrib tomentose above. There is also the occasional development 
of domatia in the axils of the secondary nerves beneath. Bark not shed- 
ding from the mature tree in strips as in S. polysperma. Produces an 
exceedingly good, fine and straight-grained, soft, red wood.

13. Shorea sp. 
For. Bur. 9432, Hutchinson, District of Zamboanga, Feb. 1908. 
Large leaves picked up from the ground. They are manifestly distinct from 
anything else which we have in the family. 
Coriaceous, oblong or oblong-lanceolate, 20 to 25 cm long, 5 to 8 cm wide; 
petiole 2 cm long. Margins distinctly inrolled. Secondary veins about 15 pairs. 
Wood dark-red, coarse and straight-grained. An exceedingly good grade of red 
lauan. A coarse grained red lauan like S. warburgii. 
14. Shorea sp. 
For. Bur. 9174, 9493 Whitford & Hutchinson, collected in the District of Zam- 
boanga, Mindanao, in Dec., 1907, and Feb., 1908, respectively. 
The leaves have much the appearance of those of Hopea plagata; but the 
wood is a red lauan and presumably a species of Shorea. Wood red, fine-grained.
