Taxonomy
The species was originally placed in the defunct genus Elodes under the name Elodes sumatrana. It was moved into Cratoxylum as C. sumatranum in 1856 by Carl Ludwig Blume. Two subspecies are recorded:[3]
- Cratoxylum sumatranum subsp. blancoi (Blume) Gogelein - Philippines
- Cratoxylum sumatranum subsp. sumatranum - the nominate infraspecific - Malesia
Distribution and habitat
Cratoxylum sumatranum is indigenous to Southeast Asia, including Borneo, Malaya, and the Philippines.[3] It is found in disturbed open areas, especially on hillsides and ridges on clay or sandy soils.[7]
Uses
The plant is harvested locally and used for its timber and for fuel or charcoal.[7] A 2021 study demonstrated that bark extracts from the species exhibited antimalarial capabilities in a laboratory setting, and could have applications as an antimalarial drug.[8]
