The Begonia oxyphylla belongs to Begoniaceae (the Begonia family). It is an evergreen shrub that is native to the southern part of Rio de Janeiro, Brazil. It grows in a humid tropical biome near the coast and grows to about 1 m tall. It is a cane-like begonia with erect, fleshy, brown, reddish hairy stems. The leaves are elongated, oblong elliptic (less than 6 cm wide), medium green on the upper surface, shiny and hairless. The small white flowers have five to six perianths and are produced in cymes at the ends of divided branches. This variant has the smallest natural distribution, but is the most common in cultivation.
