Description

This is a large emergent tree with a relatively smooth bark that is quite unlike the fissured ones of its other closely related Shorea species. Old trees later crack shallowly and irregularly, bark eventually falling off in flat plates. The oblong leaves are leathery, often folding at the midrib and dry nearly smooth. The fruits have three long wings which are auriculate at the base.
