This species is related to Garcinia gummi-gutta (Linnaeus) N. Robson (G. cambogia Desrousseaux) but the latter differs in having male flowers with a pistillode, stamens 10-20 or more, with filaments, rudimentary stigmas 3 or 4, very short or absent, and female flowers with stigmatic rays 8-10-tuberculate, free nearly to the base.

The fruit is edible, juicy, and slightly sour.
