Asia, Brunei, Indochina, Indonesia, Laos, Malaysia, Myanmar, Sarawak, SE Asia, Singapore, Thailand,

Cultivation

A plant of the tropics where it grows in rainforests with no distinctive dry season. In general, species in this genus prefer a deep, well-drained soil; young plants need some shade, but need increasing light levels as they mature. A variable species, originally described under six different specific names.

Propagation

Seed - best extracted from ripe fruits and sown immediately as they cannot withstand desiccation and lose viability within a few week. There is no period of dormancy, the seed usually germinating immediately.

Other Uses

The yellowish wood is durable and is not attacked by insects. It is used for bridges, floor supports etc, but is too hard to be used for making boards. The wood is a source of keledang timber. We have no further information for this species, but the general description of keledang is as follows:- The heartwood is yellow-brown to orange-red, darkinging to golden brown; it is clearly demarcated from the 5 - 7cm wide band of sapwood. The texture is coarse; the grain straight or interlocked; there is a lustrous, ribbon-like aspect. The wood is fairly heavy, fairly hard, durable, being moderately resistant to fungi and resistant to termites and dry wood borers. It seasons somewhat slowly with a high risk of distortion and a slight risk of checking; once dry it is moderately stable to stable in service. It has a fairly high blunting effect upon tools, stellite-tipped and tungsten carbide are recommended; the surface is fibrous and filling is recommended; it takes screws and nails poorly; glues correctly. The wood is used for furniture, house building, turnery, light carpentry, interior joinery and panelling, boxes and crates, boats etc. It is used for making high class coffins in Malaysia.
