A medium-sized or large tree. Leaves chartaceous, lanceolate- 

 acuminate, glabrous above, except for occasional hairs on the 

 midrib, paler and pubescent beneath, domatia in the axils of the 

 lower veins, 5.5 to 9.5 cm long, 2 to 3.6 cm wide, rounded or 

 subcuneate and slightly inequilateral at the base, secondary veins 

 8 to 10 pairs. Petiole 6 to 9 mm long. Young twigs slender, 

 dark brown. Fruit conical, about 4 mm high and about 3 mm in 

 diameter, surmounted by the 0.5 mm long style. Calyx-lobes 

 densely gray-pubescent, the two long ones up to 5 cm long and 

 1 cm wide, oblanceolate, pale green, with slight pubescence, prin- 

 cipal longitudinal nerves about 7, transverse veins irregular and 

 rather indistinct. Flowers in unilateral racemes and these in 

 much branched panicles. Racemes 3 cm long or less, panicles 8 

 cm long or less. Stamens 10. Anthers about 0.4 mm long, ap- 

 pendage very slender, as long as the anther. Filament short and 

 thick, 0.5 mm long, 0.3 mm wide. Ovary cylindric, 0.7 mm in

This form is a smaller tree than Hopea acuminata and has a thinner, 

 lighter, less deeply furrowed bark; the leaves are rather more pubescent 

 on the underside, and the fruit is much larger.

11. HOPEA FOXWORTHYI Elmer in Lean. Phil. Bot. 4 (1912) 1469. 

 Sibuyan. Mindanao, Zamboanga. 



This species differs from Hopea pierrei by its smaller leaves without 

 domatia and its pale-greenish fruits. 



12. HOPEA GLUTINOSA Elmer in Leafl. Phil. Bot. 4 (1912) 1470. 

 Sibuyan. Luzon, Laguna. Pan ay, Capiz. 



This is most closely related to Hopea pierrei, from which it differs by its 

 larger, glutinous fruits. 



13. HOPEA MALIBATO Foxw. in Leafl. Phil. Bot. 6 (1913) 1953. 

 Mindanao, Agusan. 



This is most closely related to Hopea beccariana Burck, from which it 

 differs in the greater size of the leaves and the fruits and in the greater 

 number of veins on the larger fruit wings. It differs from Hopea pierrei
