FURTHER INF Scientific synonym: Aglaia dookoo, A. domestica, A. aquea. Langsat is native of Malaysia, the Philippines, Java and Borneo. It is well adapted to the humid lowland tropics below 800 m of elevation, but thrives best near sea level. It requires a filtered shade and a humid almost stress-free tropical environment. A short dry season appears necessary to trigger flower differentiation. Some countries have one crop per year, while others have two. The yield is variable from 40-300 kg per tree. Mean yields of 2.5 t/ha in the Philippines and 5.6 t/ha in Thailand.
