Begonia olbia

A little-documented begonia from the Atlantic Forest of southeastern Brazil, described by Kerchove in the 19th century. There are no wild GBIF records, and no detailed habitat account was found, so the care below is extrapolated from the regional climate and from related southeastern Brazilian begonias. Treat it as a warm, humid understory plant that tolerates a drier, cooler winter.

Where it grows wild

No specific habitat description was found. Southeastern Brazilian begonias mostly grow in the shaded understory of Atlantic rainforest, on moist banks, stream edges and rocky outcrops. This is assumed, not confirmed, for B. olbia.

No elevation data. The Atlantic Forest of southeastern Brazil runs from sea level to over 2000 m, and the species' actual band is unknown.
