Distribution
A genus of five species with a distribution from New Guinea to northern Australia, Vanuatu and Fiji; one species in New Guinea: Bleasdalea papuana (Diels) Domin.
Note
Floristic treatments have placed the two species of Bleasdalea in a variety of genera, including Turrillia and Gevuina - the latter is now considered to be a monotypic South American genus; Weston & Barker (2006) accept Bleasdalea.
