A new peltate-leaved species of the genus Begonia(Begoniaceae), B. holostyla, was described and illustrated by photos. The new species was similar to B. pulvinifera in its peltate leaves and black dots on fruits, but differed in its styles combined to a half(vs combined at base), lunate stigma without a spiraled band(vs 2-cleft in a spiraled band). Additionally, the relationship of geographical distribution and morphology with the similar species, B. pulvinifera, was discussed.

Key words: Begonia sect. Coelocentrum, combined style, karst regions, peltate leaves, Vietnam
