Appearance & recognition
This Borneo-native tree produces striking pink to red fruits with longitudinal ridges. The lantern-like outline explains comparisons with starfruit, but it belongs to Baccaurea rather than Averrhoa. Male and female flowers occur on separate trees. Leathery leaves and the ridged fruit help distinguish it from round-fruited rambai.

It grows in lowland primary, secondary and riverine forests. The sweet-sour flesh around the seed is the documented edible portion. Forest and river margins are therefore part of its food story, not merely a background setting. Keeping this wild fruit as a distinct species also prevents a cultivated starfruit photograph from being used under the misleadingly similar common name.
