Begonia francisabuidii from Albay, Bicol region, Luzon Island is here described as a new species endemic to the Philippines. Belonging to section Baryanda, it resembles B. madulidii but is distinguished by shorter and puberulent rhizomes, densely hirsute stipules, reddish and pubescent petiole, smaller leaves, puberulous panicle, smaller bracts and 4-tepaled pistillate flower. According to the IUCN red list categories and criterion, B. francisabuidii is proposed to be placed in the Critically Endangered (CR) category.
