The trunk is not buttressed and can be up to 3 m in diameter and up to 30 m unbranched. It can be found in Southeast Asia where it has long been exploited for timber and latex. The latex is used for chewing gum, celluloid, linoleum, insulation of electric cables, cement, paints, paper, etc. The resinous fruits are used as torches and as mosquito repellent. The roots are used as cork substitute. The wood, on the other hand, are used for carving, pencils, matches, veneer, etc.

Other Uses: The latex, obtained by tapping the trunk, is used for the production of chewing gum, celluloid, linoleum and the insulation of electric cables[ 317 ]. Beside this it serves as admixture for cement, paints and paper[ 317 ]. The latex has a number of speciality uses such as pattern making in foundry work, for drawing boards, pencils, picture frames, dowels, carving, blackboards, wooden toys, clogs, brush handles and battery separators, and it is also used for furniture parts, door knobs, ceilings, partitioning, matchsticks, matchboxes and packing cases[ 349 ]. The resinous fruits serve as torches[ 317 ]. They are also burnt to repel mosquitoes[ 349 ]. The roots are used as a substitute for cork[ 325 , 349 ]. The heartwood is creamy white to pale straw coloured with the frequent presence of large latex canals; it is not differentiated from the sapwood. The grain is mostly straight; texture moderately fine and even; slightly lustrous; without taste but with a slight sour odour that is distinctive. The wood is very light in weight; soft; it is not durable, being susceptible to fungi, dry wood borers and termites. It seasons rapidly with only a slight risk of checking or distortion; once dry it is stable in service. The wood works easily with hand and machine tools, but they need to be kept very sharp in order to obtain a smooth finish; latex in the wood may clog the sawteeth; nailing and screwing are poor; gluing is correct. The wood is excellent for carving and is also used, among other things, for making patterns, pencils, matches, match-boxes, boxes and crates, furniture components, interior joinery and panelling, drawing boards, blockboard and veneer[ 316 , 317 , 848 ].

Cultivation details
Industrial Crop: Hydrocarbon Management: Standard Regional Crop
A plant of the wet, lowland tropics, where it is usually found at elevations up to 400 metres, exceptionally to 800 metres[ 325 , 359 ]. Requires a sunny position - the tree develops a wide crown when growing in the sun in order to 'claim' its territory[ 325 ]. Prefers a well-drained soil, often growing on hills and ridges in the wild[ 325 ].
Carbon Farming
-
Industrial Crop: Hydrocarbon
Materials, chemicals and energy include bioplastics, rubber, biomass products gasoline, jet fuel, diesel, butane, propane, biogas. Plants are usually resprouting plants and saps.
-
Management: Standard
Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
-
Regional Crop
These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.

Plant Propagation
Seed - the small seed has a limited viability of less than a year. Pre-treatment is not necessary, but soaking the seed in water for 12 hours prior to sowing can speed up the germination process[ 325 ]. Germination rates are usually good, with 80 - 90% of the seeds sprouting. Seedlings can be potted up when the first pair of leaves has emerged and planted out when 30cm tall.
