Taxonomy Comments: Rosatti (1989) and Drapalik (1969) expressed considerable doubt about whether two species should be recognized; their view, supporting the recognition of a single species in our area, is followed here for now. However, studies by Krings & Xiang (2004, 2005) suggested that two entities should be circumscribed at the varietal level. Drapalik (1969) considered the basionym "suberosa" as not applicable to Matelea of North America; Reveal & Barrie (1992) lectotypified the name, resulting in it applying to our material. The epithet "suberosus" has priority over "gonocarpus".
