Abstract: Garcinia section Dicrananthera Pierre, Fl. Forest. Cochinch. 1 (5): 8. 1883; M. Gaudeul et al., PhytoKeys 239: 95. 2024. Type. Garcinia thorelii Pierre, Fl. Forest. Cochinch. 1 (4): t. 62. 1882. Garcinia section Dicrananthera is distinguished by the presence of a pair of interpetiolar stipuliform structures (rare in Clusiaceae); leaves with prominent, widely spaced secondary veins and scalariform tertiary veins; axillary or terminal cymose inflorescences with three to many flowers [i. e., G. yaatapsap (3–5 - flowered), G. paucinervis (4–10 - flowered), G. stipulata (4–6 - flowered), G. nujiangensis (6–10 - flowered), and G. thorelii (20–40 - flowered thyrse)]; flowers with 4 sepals and 4 petals; male flowers with numerous stamens united into an annular mass encircling and attached to the pistillode (i. e., G. stipulata and G. yaatapsap) or united into 4 bundles surrounding the pistillode (i. e., G. nujiangensis, G. paucinervis, and G. thorelii), 2 - thecous anthers; 1–2 - locular ovaries; unlobed and smooth stigmas; and fruits with a smooth surface and unlobed. Distinguishing morphological characters reported here for this section were taken from Pierre 1882, Pitard 1910, Chun and How 1956, Jones 1980, Li 1981, Li et al. 2007, Stevens 2007, Gaudeul et al. 2024, and from our observations. A section of five species worldwide (Gaudeul et al. 2024); one species in Thailand.
