Cotylelobium lanceolatum, derived from lanceolatus, is found in some Asian kerangas forests.
The name is derived from Latin (lanceolatus = in the form of a lance) and refers to the shape of the leaf blade. The species is found in Peninsular Thailand, eastern coastal areas of Peninsular Malaysia, the Anambas Islands and Borneo. C. lanceolatum is a canopy tree, up to 45 m, found in kerangas forests on raised beach terraces and sandstone plateaux and on organic soils over limestone. Sundaland heath forest, also known as Kerangas forest, is a type of tropical moist forest found on the island of Borneo, which is divided between Brunei, Indonesia, and Malaysia, as well as on the Indonesian islands of Belitung and Bangka, which lie to the west of Borneo.
