Flowers ca. 11 mm diameter, white-yellow-pink-red, placed in panicles. Fruits ca. 100 mm long, green-yellow, elongate, fleshy capsules.

Probably not native in Borneo where it is usually planted in gardens and near villages. Sometimes escaped into coastal, mangrove, keranga and mixed dipterocarp forests up to 400 m altitude. On alluvial sites and hillsides with sandy to clay soils.

The roots are boiled and the solution is used against internal wounds. The leaves are boiled and applied against skin itches. The fruits are edible but sour (Star fruit).

Originally probably from Java, but currently cultivated pantropical.
