Garcinia section Macrostigma is characterized by its axillary or terminal cymose inflorescences with two to many flowers (in a simple cyme or in fascicles of several simple cymes), or a solitary flower (in female flowers); 4 (– 5) - merous flowers [4 - merous, e. g., G. nuntasaenii ; 5 - merous, e. g., G. phuongmaiensis , G. prainiana ]; male flowers with numerous stamens united into a central column, sometimes lobed with lobes equaling number of petals [a single weakly 4 - lobed bundle, e. g., G. nuntasaenii ], or into completely separate antepetalous bundles [united into 5 bundles, e. g., G. phuongmaiensis , G. prainiana ]; androecium often adnate to the petals to varying degrees; 2 - thecous anthers; pistillode absent in male flowers, but rudimentary or well-developed pistillode present in some species; (– 3) 4–8 - locular ovaries; unlobed or lobed and smooth or papillate stigmas; and fruits with a smooth surface, unlobed or faintly, shallowly or deeply lobed. Distinguishing morphological characters of this section based on Gaudeul et al. 2024, which includes additional information.

A section of 29 species worldwide ( Gaudeul et al. 2024); two species in Thailand (i. e., G. nuntasaenii and G. prainiana ).
