Two new species of Begonia (Begoniaceae) from the Atlantic coastal forest in the state of Sao Paulo, Brazil

Begonia salesopolensis and B. jureiensis, known only from a montane forest in the state of Sao Paulo, Brazil, are described and illustrated. The former belongs to section Ewaldia, but it is distinguished from the other taxa of this section by its fleshy capsules with rudimentary or absent wings. The flattened style branches, obconical anthers, and the bilamellate placentae, ovuliferous throughout place B. jureiensis in section Pereira, and the peltate, glabrous leaf blades distinguish it from the other species of this section, B. edmundoi Brade.
