Cultivation Details

A plant of lowland tropical monsoon areas, where it can be found at elevations up to 500 metres. It prefers a dry season of 3 - 6 months[].
Young trees grow best in the shade of the forest, but become increasingly light-demanding as they grow larger[]. They are most commonly found growing on easily friable sandy or ferrallitic soils[]. Plants are tolerant of seasonal inundation of the soil[].
Members of this genus generally only regenerate naturally in the shade of the forest. Seedlings and saplings can persist in dense forest shade for many years. In their first 2 years the young plants cannot tolerate major openings in the canopy, but after they are well established (about 120cm tall) the canopy can be opened up around them to speed up their growth[].

Other Uses

A grey brown resinous oil is obtained from the tree. It is mainly used locally, being traditionally employed in the preparation of torches[].
The oil is obtained by cutting a hole in the trunk near the base (about 90 - 150cm from the ground) and then dipping out the resin with a spoon as it collects there. To prolong the flow, a fire made from dead leaves or brushwood is made in the hole at intervals - this burns off the dried resinous film and allows the resin to flow again[, ].

The heartwood is red brown to dark red; it is distinctly demarcated from the thin band of reddish sapwood. The wood is heavy with a coarse texture. It is durable and resistant to termites and insects. It is used in the construction of houses and carts[].
