Notes.

Byrsonima currently comprises 164 accepted species (49 threatened species; Suppl. material 1) of trees, shrubs, or subshrubs endemic to most biomes of the Neotropical region from swamps in the State of Florida (USA) to rainforests, savannas, dry forests, and grasslands of Southern Brazil (Almeida et al. 2020; POWO 2024). Two subgenera are currently recognised in Byrsonima (subg. Byrsonima and subg. Macrozeugma Nied.), but neither is monophyletic (Francener 2016). There is no updated identification key for all species of Byrsonima, but for regional treatments, see Anderson (1981) for the Guyana Highland, Almeida et al. (2020) for Brazil, Pool (in prep.) for Mesoamerica, and Anderson (2016) for North America.
