Neobalanocarpus heimii, known as chengal, is a monotypic genus of tall tropical hardwood trees from the Malay Peninsula, prized for its timber and listed as endangered. It is a forest tree, not a garden or houseplant, and growing it requires conditions of a large lowland tropical forest.
Neobalanocarpus is a monotypic genus of plants in the family Dipterocarpaceae. The single species, Neobalanocarpus heimii, is a tropical hardwood tree. Common names for the tree and its wood products include chengal, chan ta khien, chi-ngamat, takian chan, and takian chantamaeo. The tree grows over 60 m (197 ft) tall. Chengal is considered the number one wood (classified as heavy hardwood) of Malaysia and export of logs is prohibited due to its scarcity. The species is listed as endangered on the IUCN Red list.
Neobalanocarpus heimii is endemic to the Malay Peninsula and grows under quite a range of conditions of soils and topography in Peninsular Malaysia (and southern Thailand) from low flat semi-swamp to hills, but appears to thrive best on undulating land with light sandy soils. See Wildlife of Malaysia. It is now extinct in Singapore, and possibly extinct in Thailand.
Chengal has been used for furniture making, house and boat-building. Despite its extreme strength and hardness, chengal is highly flexible before it is fully cured, making it suitable for plank bending (boat building). It is also highly resistant to rot, fungi and mildew. In addition, chengal has a relatively low shrinkage ratio (only inferior to teak), which makes it excellent for applications where it undergoes periodic changes in moisture. Chengal, like teak, has the unusual properties of being both an excellent structural timber for framing, planking, etc., while at the same time being easily worked and finished to a high degree.
