Chrysanthemumdabieshanense , a new name for  Chrysanthemumvestitum var.  latifolium (Asteraceae, Anthemideae).

Recent phylogenetic analyses have revealed that Chrysanthemumvestitumvar.latifolium and C.vestitumvar.vestitum were placed in different clades based on their chloroplast genomes and nuclear LFAFY gene sequences. Accordingly, based on previous morphological analysis, molecular phylogenetic results, fieldwork, and herbarium studies, Chrysanthemumvestitumvar.latifolium should be raised to the species level. Considering the condition of the material found and Articles 6.9, 6.11, 41.2, 58.1 of the International Code of Nomenclature for Algae, Fungi, and Plants ( Shenzhen Code ) that is currently in force, Chrysanthemumdabieshanense Z.X.Fu, A.G.Zhen, & Y.P.Ma, nom. nov. is proposed as the new name for Chrysanthemumvestitumvar.latifolium J.Zhou & Jun Y.Chen. The detailed emended description, distribution map, insights into its habitat, and an updated comparative morphological study are presented in this study.
