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).

(If the plant you're looking for doesn't show up in the auto-complete list, that means it either isn't described in Flora of North America yet, or it's listed under a synonym. And please note that Flora of North America is still missing several plant families, including Apiaceae, Boraginaceae, and Polemoniaceae.)
