Begonia sect. Ephemera Moonlight
Taxon 67(2): 291 (Moonlight et al. 2018).
– Type: holotype: Begonia exigua Irmsch.
Notes
This section was described by Moonlight et al. (2018) to accommodate a well-supported clade of annuals or short-lived perennials native to central and South America. This section is most similar to B. sect. Doratometra but, in Peru, can be distinguished by its palmate rather than palmate-pinnate venation.
