Saposhnikovia

Saposhnikovia is a monotypic genus of flowering plants in the family Apiaceae. Its only species is Saposhnikovia divaricata, known as fángfēng 防風 (lit. "protect against the wind") in Chinese, bangpung in Korean, and siler in English. The plant is still frequently referenced under the obsolete genus name Ledebouriella in many online sources devoted to traditional Chinese medicine. It was first described as Stenocoelium divaricatum by Nikolai Turczaninow in 1844, and transferred to Saposhnikovia in 1951.
