At first glance Begonia aeranthos appears to be an oversize specimen of B. glabra, but the peltate leaves and falcate-ascending capsule-wings contradict that identity. Further the linear spiral stigmas of B. aeranthos bar it from section Pritzelia where B. glabra is. In fact, B. aeranthos does not fit any of the sections used by Irmscher in the Pflanzenreich, and requires either the broader definition of Pritzelia or the making of a new section.
