The two varieties, A. nitidus var. macrocarpum and var. montanum could not be distinguished, because of a continuous range in sizes of the leaf blades (var. montanum with smaller leaves) and fruits (var. macrocarpum with larger fruits). There was also no geocline in these sizes, though plants from higher altitude tend to have smaller leaf blades and smaller fruits. The plants in Thailand and the Malay Peninsula are generally somewhat more hairy when young and the bracts of the axillary buds are larger and more distinct.


Sumatra: Fruit produces edible oil. Borneo (Sabah): Wood used for construction purposes (Bajau).
