Gynura japonica (Thunb.) Juel (1891: 86) .

Senecio japonicus Thunberg in Murray (1784: 756). Senecio luridus Salisbury (1796: 196) , non. illegit. superfl. Porophyllum japonicum (Thunb.) Candolle (1836: 650) . Fig. 1C .

Type:— JAPAN. Nagasaki, Thunberg s.n., as “ Jacobaea japonica ” (lectotype designated here: UPS-THUNB 19669!) .

Notes:—When treating Senecio japonicus as a combination based on Arnica japonica L. f. ( Wijnands 1990: 12), Wijnands (1990: 7) designated UPS-THUNB 19669 as the lectotype of A. japonica . This, however, should not be considered as an effective lectotypification for S. japonicus itself. The lectotypification for S. japonicus is designated here.

Kleinia japonica is generally accepted as a combination published by Lessing (1831: 134) based on Senecio japonicus Thunb. However, Lessing (1831) only suggested S. japonicus being a member of Kleinia and did not make a formal combination. According to Art. 35.2 of ICN ( Turland et al. 2018), Kleinia japonica is not validly published.

UPS-THUNB 19996; the leftmost part (red arrow) belongs to Syneilesis sp., and the right three parts (blue arrows) are designated as the lectotype of Arnica japonica Thunb. C. UPS-THUNB 19669. D. LINN-HS 1322.1; inserted images show the enlarged annotations; the lower one reads “H L. fil. e Japonia Thunb.”, and the upper one reads “Arnica japonica fol. pinnatifidi”, with a word between “fol.” and “pinnatifidi”, seemingly “pedatifidi”, being deleted.
