Notes
This section consists of scandent species found mostly in the Atlantic Forests of Brazil with the notable exception of B. glabra , which is found as far north as Mexico and across Amazonia, including in Peru. It is superficially similar to B. sect. Rossmannia but can be distinguished by its axillary, cymose inflorescences rather than terminal, thyrsoid inflorescences.
