<strong>A new tuberous species of <em>Begonia</em> L. (Begoniaceae) from southern Yunnan, China</strong>

A new species, Begonia depingiana from southern Yunnan, China, is described and illustrated. Morphologically, B. depingiana is similar to B. namkadingensis in habit, its tuberous rootstock and tepal number of the male and female flowers, but significantly differs by its 3 stigmas, and 3-locular ovary. It also resembles B. pellionioides in its pinnate leaf venation, but distinguished by the indumentum characters of its stem and ovary, tuberous rootstock, shorter plant, and unequally 3-winged capsule.
