The morphological description of Aster procerus Hemsley was not complete enough in the original literature when compared with the specimen which we collected from its type locality. Additionally, there is a lack of reports from cytology and molecular phylogeny in recent studies. We made a detailed description of A. procerus and did some studied about cytology and molecular phylogenetic on this species, and provided new evidences for the revision of Aster. The results reveal that: (1) there are some new characteristics for A. procerus that basal leaves pinnatilobed, larger when matured, up to 26 cm in length and 8 cm in width, and receptacle convex. (2) The cytology evidence showed that the number of chromosome was 2n = 18 and the karyotype formulae was 2n = 2x = 16 m + 2 M, belongs to 1A. (3) The molecular phylogenetic analysis which based on ITS and ETS showed that these two populations of A. procerus formed a highly supported clade (LP = 100, PP = 1.00) and was nested within the core Aster clade (LP=100, PP=1.00). Furthermore, phylogenetic analysis indicated that A. procerus was sister to Turczaninovia fastigiata (Fischer) Candolle. Our results supported A. procerus belongs to Aster and suggested transferring T. fastigiata to Aster.
