Range & habitat
Swamp jelutung is a latex-producing tree of Sumatra and Borneo’s peatlands. Unlike many lowland timber trees, it is suited to wet peat soils. Its presence connects the forest canopy with a waterlogged landscape: draining that landscape changes the conditions in which the tree and its neighbours regenerate. It belongs to Apocynaceae, not to the dipterocarp family of swamp kapur.

Research in Central Kalimantan examines jelutung in agroforestry and peatland rehabilitation, including the Kanarakan landscape. Latex offers a forest product without requiring the whole tree to be felled. Establishing trees nevertheless depends on suitable water conditions and management; planting jelutung alone cannot repair a drained peat ecosystem. Its story is as much about livelihoods and hydrology as about a useful sap.

Jelutung also supplies cambium to Bornean orangutans in Sebangau. The field study uses the older name Dyera lowii, a synonym of Dyera polyphylla, for this food tree.
