Protologue: Penerb. Madj. Ilmu Peng. Indon. 1: 52 (1959). Also in: Reinwardtia 4: 514 (1959).

• Tarrietia simplicifolia Masters (1874).

• Indonesia: teraling (Sumatra)
• Malaysia: mengkulang siku keluang (Peninsular).

Peninsular Malaysia, Sumatra, Borneo.

The timber is commonly used as mengkulang, also for export.

• A large tree, up to 50 m tall with straight and columnar bole up to 135 cm in diameter, buttresses large.
• Leaves simple, densely scaly beneath, petioles 2.5-6 cm long.
• Panicles up to 9 cm long.
• Fruit with large wing, glabrous.

H. simplicifolia is the most important species of mengkulang timber. It is widely distributed but always occurs scattered in lowland mixed dipterocarp forest on flat or undulating terrain with well-drained clay soils, up to 300 m altitude. The wood is often traded together with Shorea spp. (dark red meranti). The mechanical properties of the wood are close to those of teak, but the wood is stiffer and tougher. The density of the wood is 520-890(-990) kg/m³ at 15% moisture content. See also the table on wood properties.
