Notes

This species had previously a much wider circumscription including all species in the genus (Leeuwenberg, 1980). In the revision by Struwe & Albert (2004), Potalia resinifera was resurrected and 7 new species were recognized, some of which previously had been identified as P. amara. The closest relative might be P. turbinata Struwe & V.A. Albert from C America, which has the most similar flowers and fruits.
