Distribution:—The species is found in Vietnam (Ha Giang Province) and in SE China (Guangxi and Guangdong provinces).

Ecology and phenology:—It grows in evergreen broad-leaved submontane forests on granite and shale at elevations of about 1200 m a.s.l. Flowers in July–August.

Conservation status:— The species is known from Guangxi and Guangdong provinces of SE China and Ha Giang Province of N Vietnam, forming a narrow triangle with an approximate square of not more than 15000 km 2.
