03FC87825C41E671FF30FBE29520F985.taxon	discussion	Populus × jrtyschensis was described for a natural hybrid species distributed aside Ertix River. While the name was originally published, the multiplication sign ‘ × ’ was added ahead of the epithet (Wang & Dong 1982), declaring its hybridity. Its parents were then indicated to be P. laurifolia and P. nigra based on the transitional morphology characters between putative parent species (Yang 1992, 2012), and molecular evidence supporting this hypothesis was provided from a DNA barcode research (Feng et al. 2013). However, the parentage statement of P. × jrtyschensis would make it a synonym of P. × berolinensis. Populus × berolinensis was described from Berlin and was thought to be a hybrid between P. laurifolia and P. nigra var. italica. Although it is in a rank inappropriate in relation to that hybrid formula (Art. H. 5.2 of ICN), P. × berolinensis is nevertheless the correct name applicable to all hybrids between P. laurifolia and P. nigra (Art. H. 5 Note 1 and Ex. 1 of ICN). Hence we propose a new combination for P. × jrtyschensis (Fig. 1 A).	en	Shang, Ce, Zhang, Limei, Zhang, Zhixiang (2016): New combinations for nothotaxa of Populus (Salicaceae) from China.

03FC87825C40E670FF30FB3193E0F90A.taxon	discussion	Populus × gansuensis and P. × xiaozhuanica were described based on two artificial hybrids, and their hybrid formula were cited as P. nigra var. thevestina × P. simonii and P. nigra var. italica × P. simonii respectively. Both of the two names were in an inappropriate rank, since the rank of a nothotaxon should be the lowest rank of its parent taxa, if ranks of their parents are unequal (Art. H. 5.2 of ICN). However, either of them may be nevertheless correct for P. nigra × P. simonii (Art. H. 5.2 Note 1 and Ex. 1 of ICN). According to Art. H. 4, only one name could be correct in the appropriate rank corresponding to a particular hybrid formula. Another name for a hybrid between P. nigra and P. simonii, P. × xiaohei was published in the same article, competing for the priority of P. nigra × P. simonii with P. × gansuensis and P. × xiaozhuanica. Given that P. × xiaohei is a name in the appropriate rank, we propose two new combinations for P. × gansuensis and P. × xiaozhuanica (Fig. 1 B). When P. × gansuensis was published, Yang Xi-Lin 79014 ♀ was cited as the type and two sheets of Yang Xi-Lin 79014 ♀ were found in LZD. According to the collecting record, the two specimens belong to the same gathering and should be treated as syntypes (Art. 9.5). With more mature leaves preserved well, LZD barcode 02727 is designated as the lectotype.	en	Shang, Ce, Zhang, Limei, Zhang, Zhixiang (2016): New combinations for nothotaxa of Populus (Salicaceae) from China.
