Abstract
Begonia austroyunnanensis, a new species from Yunnan (China) is described and illustrated. This new species is similar to B. subhowii in having short erect stems, obliquely ovate leaves and white flowers, but can be distinguished by its stem, petioles and peduncle having conspicuous, red, linear dots and the much longer abaxial wing of the capsule. A detailed description, data on distribution, ecology and an illustration are provided.

滇南秋海棠
The new species is similar to B. subhowii S. H. Huang
in having short erect stems, obliquely ovate leaves, and
white flowers, but can be distinguished by its its stem,
petioles, and peduncle having conspicuous, red, linear
dots and the much longer abaxial wing of the capsule.
Etymology: The specific epithet “austroyunnanensis” refers to the type locality in southern Yunnan. Chinese name is proposed here as“滇南秋海棠” (滇南- refer to the southern Yunnan province, 秋海棠- refer to Begonia).
