Notes: —Several collections, including S.K. WU 2741 (KUN, PE), T.T. Yu 7102 (KUN, PE, WUK) and Q.S. Zhao 6342 (CDBI) from Muli, southwestern Sichuan, E.D. Liu et al. 2222 (KUN) from Luquan, northeastern Yunnan, K.M. Feng 2102 (KUN, PE), Q.E. Yang & H.Z. Kong 98-534 (PE) and Zhongdian Exped. 1447 (KUN, PE) from Zhongdian, northwestern Yunnan, are very similar to Ligularia nelumbifolia in general aspect, but differ in having 3 phyllaries and 2–3 florets. Further studies are needed to determine if these collections should be referred to L. nelumbifolia or L. tongkyukensis Handel-Mazzetti (1938c: 288) , or even represent a hitherto undescribed species. Ligularia tongkyukensis , described from Nyingchi, southeastern Xizang (Tibet) and characterized by, among other characters, having 3 phyllaries and 3 florets, is currently known only from the type material and imperfectly understood yet.

Based on the corymbose inflorescence and palmately veined leaves, Liu (1989) placed Ligularia nelumbifolia in L. sect. Corymbosae (Franchet 1892: 290) Handel-Mazzetti (1938a: 107) ser. Retusae Liu (1985: 64) . From a morphological perspective, however, this series as currently defined seems to be quite heterogeneous pending a recircumscription. Ren & Yang (2014) has reduced L. kangtingensis Liu (1985: 69) from this series to the synonymy of L. hookeri ( Clarke 1876: 69) Handel-Mazzetti (1938a: 127) , which, according to Liu (1985, 1989), belongs to L. sect. Ligularia ser. Ligularia . It seems that only Ligularia retusa Candolle (1838: 314) , the type species of this series, and its two morphologically closest relatives, L. cremanthodioides Handel-Mazzetti (1925: 13) and L. phoenicochaeta ( Franchet 1893: 295) Handel-Mazzetti (1925: 13) , should be retained within L. ser. Retusae. One or even more new series may be proposed to accommodate the remaining species, including L. nelumbifolia .
