Abstract :A taxonomic reassessment of the Tanacetum aureum insert ignore into journalissuearticles values(Lam.); Greuter, M.V.Agab. & Wagenitz insert ignore into journalissuearticles values(Asteraceae, Anthemideae); species group was performed. This group of species is distinguished by herbaceous perennial habit, insert ignore into journalissuearticles values(1-);2-10insert ignore into journalissuearticles values(-80); disciform capitula, with compact to lax corymbs and strongly to moderately convex receptacle. A multivariate statistical analysis of 58 morphological characters using Ward cluster, principal component analyses, and molecular phylogenetic analyses of nrDNA ITS and cpDNA rpL32-trnLinsert ignore into journalissuearticles values(UAG); + ndhF-rpL32 spacer sequence datasets were conducted. Both datasets corroborated that T. aureum, T. oligocephalum insert ignore into journalissuearticles values(DC.); Sch.Bip., and T. heimerlii insert ignore into journalissuearticles values(Nabelek); Parsa could be differentiated as separate species. An identification key of the studied taxa and a description and conspectus of the species are presented.
