Pistillate flowers: sepals 2 [–3], distinct; petals 0; nectary absent; pistil 2 [–3] -carpellate; styles 2 [–3], connate proximally, unbranched. Fruits capsules.

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).
