Lectotypification of Ligularia tsangchanensis View in CoL and of L. muliensis
The type material of Ligularia tsangchanensis consists of ten specimens of four collections from northwestern Yunnan, China. They are all syntypes ( McNeill et al. 2012). Hu (1967) cited J.M. Delavay 631 from Cang Shan (= Tsang-chan), which includes four sheets, as the type, but she did not specify the herbarium in which the type was conserved and also did not annotate any of the four specimens as the holotype. Hu’s (1967) citation should be considered as a first-step lectotypification ( McNeill et al. 2012: Art. 9.17 & 9.9). Here we designate the specimen P00723348 ( Fig. 1A View FIGURE 1 ), which matches perfectly the original Latin description and also exactly conforms to the specific epithet with respect to the collection locality, as the lectotype of L. tsangchanensis and its basionym, Senecio tsangchanensis .
The type material of Ligularia muliensis includes at least six specimens of two collections. Two specimens of J. F. Rock 16582 kept in B and W were designated by Handel-Mazzetti (1938) in the protologue as the type and thus those of J. F. Rock 16683 should be regarded as the paratypes. From B we have been unable to trace the type sheet (most likely destroyed during World War II). In W there is only a paratype sheet ( W1937-0000419 A), with a sketch of a stem leaf ( W1937-0000419 B) from the type sheet in B being attached to it ( Fig. 3D View FIGURE 3 ). One sheet of J. F. Rock 16582 is kept in US. This specimen ( US 00115984; Fig. 2 View FIGURE 2 ) perfectly matches the original Latin description of L. muliensis , and thus we designate it as the lectotype of this name .
