hairy, and usually infested with large galls. The flowering and 
fruiting specimens which have been referred to this from the 
Philippines and elsewhere (Brandis, etc.) have nothing to do with

crinitus.

“ Nut sub-cylindric. A native of Prince of Wales’ Island." 
This is the whole of Roxburgh’s description. It is not possible to 
guess what he referred to, but it was probably not a Shorea.

Trees with large coriaceous leaves drying brown. Panicles 
axillary and terminal, velvety. Flowers sessile; sepals and petals 
as in Shorea. Stamens 15 in 3 rows, inner row longer with no 
awns, 2 outer with awns. Ovary conical. Fruit ovoid, large, 
pericarp woody; sepals much thickened, woody, outer 3 form¬ 
ing linear-oblong wings about as long as the fruit or shorter 
(rarely fully developed as in Shorea ). Species about 5, chiefly 
Bornean. 
Usually referred to a section of Shorea and connected with it 
by P. Ghysbertiana. The closely allied P. Beccariana Dyer gives 
the important fat, Minyak Tengkawang.
