Abstract
Recent exploration in Mt. Ararat, Bayugan City, Agusan del Sur resulted in a collection initially identified as Begonia bolsteri, a poorly known Philippine endemic species first described over a century ago. Examination of the types of this species and the type of B. colorata led us to the conclusion that these names represent the same taxon, and we place them in synonymy under the earlier name of B. colorata and designate lectotypes for both names. In this paper, we provide a comprehensive description for the species and photographs to facilitate easy identification.
