Discussion
Species 5 (1 in the flora).
Species of Pleradenophora were historically mostly classified within Sebastiania. Molecular phylogenetic analyses show that Sebastiania in the broad sense is polyphyletic and indicate a close relationship of Pleradenophora with a West Indian clade containing Bonania A. Richard, Grimmeodendron Urban, and Hippomane (K. Wurdack et al. 2005).
Selected References
None.
