Polygonatum tsinlingense

The name Polygonatum tsinlingense has not been treated at species level or even as a synonym in any recent floristic works ( Jeffrey 1980, Chen & Tamura 2000). Morphological comparisons of type specimens revealed that P. tsinlingense and P. gracile are heterotypic synonyms. Thus, the earlier validly published name, P. tsinlingense , has priority (Art. 11.4 of ICN, McNeill et al. 2012). In the protologue of P. tsinlingense two gatherings were cited by Tsui (1949) without designation of a type. The first, T.N.Liou 10910, has not been located and was not cited by Li (1966), which suggests that it was probably already lost at that time. The second is still extant, W.Y.Hsia 4238 (PE 00223893, PE 01432739), and was also cited by Li (1966), which substantiates my own morphological comparisons that these two names are to be referred to the same species. Thus, the specimen PE 00223893 is here selected to serve as the lectotype (Arts. 9.2 and 9.11 of ICN, McNeill et al. 2012).
