Distribution and habitat:— Colombia, Ecuador, Perú, Venezuela. Begonia buddleiifolia is known from the northern slopes of the Cordillera Oriental in Venezuela; the eastern slopes of the Cordillera Oriental in Colombia and the north of the Cordillera Occidental and Cordillera Central in Colombia; and the eastern slopes of the Andes and Amazonia in Ecuador and Perú.

Taxonomic comments:— A number of specimens from Bolivia have been identified as Begonia buddleiifolia but on closer examination these all appear to be specimens of B. chaetocarpa Kuntze or B. bangii Kuntze in the distantly related B. sect. Ruizopavonia. Both species superficially resemble those of B. buddleiifolia but they can easily be distinguished by their cymose inflorescence structure.

IUCN Redlist Assessment:— Begonia buddleiifolia is widespread and locally abundant throughout its range, much of which is within protected areas. Accordingly, we assess B. buddleiifolia as Least Concern (LC).
