Begonia sceptrum
B. sceptrum is a historical name for the Brazilian B. aconitifolia, a shrubby begonia about 1 m tall with deeply lobed leaves and panicles of pink flowers. It is endemic to the Atlantic Forest of Rio de Janeiro, where it grows as a terrestrial subshrub in rainforest and on rocky outcrops. The only GBIF record under this name is a garden plant in the USA, so the measured climate should be ignored.
Where it grows wild
The Brazilian flora, as served through GBIF for B. aconitifolia, lists it as a terrestrial subshrub of Atlantic rainforest and rocky-outcrop vegetation. That suggests shaded to partly bright forest on well-drained ground.
