Type:— JAPAN. Thunberg s.n. (lectotype first-step designated by Wijnands (1990: 7): UPS-THUNB 19996!; second-step designated here: the right three parts of UPS-THUNB 19996!) .

Notes:—The authorship of Ligularia japonica has generally been ascribed to “Less.” or “(Thunb.) Less.” However, as already pointed out by Dress (1962), Lessing (1832) did not make a formal combination, although he suggested that Arnica japonica Thunb. should be transferred to Ligularia . Ligularia japonica was thus not validly published by Lessing (1832).

Following Lessing (1832), Candolle (1838: 316) proposed the combination Ligularia japonica , although he clearly mentioned that he did not know the species well (“non satis nota”). Candolle (1838: 316) included both Arnica japonica L. f. and A. japonica Thunb. as synonyms. This made L. japonica a combination based on Linnaeus fil.’s name, which had priority.

Erythrochaete palmatifida Sieb. & Zucc. has generally been accepted as the earliest legitimate name for Arnica japonica Thunb. (e.g., Dress 1962; Wijnands 1990), and Senecio palmatifidus and Ligularia palmatifida are considered as combinations based on E. palmatifida . However, Doronicum japonicum Lamarck (1786) , which has long been overlooked, is actually an earlier replacement name for A. japonica Thunb. This makes Erythrochaete palmatifida a superfluous name, because the epithet of D. japonicum should have been adopted in Erythrochaete . However, S. palmatifidus and L. palmatifida are still legitimate, because, in Senecio and Ligularia , the epithet of D. japonicum has been preoccupied by S. japonicus Thunb. and L. japonica (L. f.) DC., respectively. Senecio palmatifidus thus should be treated as a replacement name for D. japonicum in Senecio , and L. palmatifida is a combination based on S. palmatifidus .

The lectotype of Arnica japonica Thunb., UPS-THUNB 19996, is mixed. The leftmost part has a peltate leaf, indicating that it is a member of Syneilesis . The right three parts belong to Ligularia japonica and are here designated as the lectotype.
