pubescent on both sides. Bacemes equalling or shorter than the leaves. 
Bracts subrotund, glabrous within, pubescent and ciliate without, yellow, 
4 mm long, 3 mm wide. Calyx laciniae lanceolate, outside covered with 
simple, adpressed, cinereous, sericeous hairs, glabrous within. Petals 
three or four times as long as the calyx, oblong, glabrous within, sericeous 
without. Stamens 15; appendix to connective sometimes longer than 
the anther cells. The three larger segments of the fruiting calyx oblan- 
ceolate, obtuse, 6-nerved, transverse veins distinct, margin minutely ciliate, 
clear, base dilated, sparsely villous with stellate hairs. Fruit ovoid, 
acuminate. Only the immature fruit has been described. 
None of our collections are in fruit and only one in flower. The 
sterile material shows a very great range of variability in shape and 
texture, and it is altogether probable that the following list contains 
representatives of what will prove to be several distinct species when we 
have more complete material for study. 
From observations made by different foresters it seems that this species 
and Hopea plagdta produce wood of almost the same quality and ap- 
pearance, but that the trees may be distinguished by the bark, which is 
thick, black and coarsely furrowed in H. plag'ata and thin, gray and not 
coarsely furrowed in this species. Both furnish a high grade of the 
timber known as yacal , which corresponds very closely to the selangan 
batu of Borneo and the tlimgan of Burma.
