Neotypification of Aconitum puchonroenicum (Ranunculaceae) from the Korean Peninsula

Aconitum Linnaeus (1753: 532) (Ranunculaceae) consists of about 400 species and is widely distributed in temperate regions of the Northern Hemisphere (Tamura 1993, Brink & Woods 1997, Li & Kadota 2001, Luo et al. 2005). This genus has been usually divided into three subgenera: A. subg. Aconitum, A. subg. Lycoctonum (Candolle 1817: 367) Petermann (1846: 15), and A. subg. Gymnaconitum (Stapf 1905: 178) Rapaics (1907: 139) (Bisset 1981, Kadota 1987, Li & Kadota 2001, Lim & Park 2001, Wang et al. 2009). Among them, A. subg. Lycoctonum is perennial and rhizomatous and consists of about 40 species (Tamura 1995, Hong et al. 2017). In the Korean Peninsula, eight species and one variety have been reported in this subgenus (Lim et al. 2017, Korea National Arboretum 2017), of which four species, namely A. pseudolaeve Nakai (1935: 139), A. pteropus Nakai (1937: 400), A. puchonroenicum Uyeki & Sakata (1938: 14), and A. quelpaertense Nakai (1935: 145), are endemic to the Korean Peninsula.
