Abstract
Aconitum polycarpum Chang ex W. T. Wang described from Yunnan, China, is re-described here with illustrations of the helmet and nectary based on the herbarium specimens. Sect. Sinaconitum W. T. Wang was recognized originally as a monotypic section which included a sole species, A. polycarpum. However, it is clarified that another species, A. heterophyllum Wall. ex Royle from the Western Himalayas, also belongs to this section. The ranges of both species are geographically segregated from each other by approximately 1,500 km. This is the first report of prominent vicariance in the Great Himalayas.
