Type species.

Tetrapterys inaequalis Cav.

Notes.

Tetrapterys comprises 56 currently accepted species (18 threatened species; Suppl. material 1) of shrubs and lianas endemic to rainforests, savannas, and seasonally dry tropical forests of the Neotropics from Mexico (North America to Argentina (South America; POWO 2024). There is no updated identification key for all species of Tetrapterys , but for regional treatments, see Anderson (1981) for the Guyana Highland, Almeida et al. (2020) for Brazil, and Pool (in prep.) for Mesoamerica.
