An endangered species, resident of lowland freshwater peat-swamp forests and native to Singapore, the Kempas is a lofty emergent tree that bears leathery pinnate leaves. Its leaflets vary between being egg-shaped to lance-shaped. Its straight cylindrical trunk can grow up to 25 m tall, with the branches occurring at the top of the tree, and its wood is highly sought after for timber. This giant also develops huge thick plank buttresses up to 6 m in height, much taller than any man!
When this tree begins to bloom, its crown becomes densely covered in white flowers. Its fruit is a flat and thin oblong pod about 3–4.5 cm wide by 9.5–15 cm long and contains a flat seed.
