The genus Cyclorhiza is endemic to China and belongs the Apiaceae family, which widely distributed in Himalaya-Hengduan Mountains (HHM) region. However, its morphology, phylogeny, phylogeography, taxonomy, evolutionary history were not investigated due insufficient sampling lack of population plastome data. Additionally, we found that Seseli purpureovaginatum was similar members but resembled species indicating taxonomic position S. needs be re-evaluated. First, observed morphology genus. Second, newly sequenced four plastomes conducted comparative analyses. Third, used internal transcribed spacer (ITS) chloroplast DNA (cpDNA) (matK, trnQ-rps16, trnD-trnT) from 27 populations totaling 244 individuals explore genetic diversity structure. Finally, performed phylogenetic analyses based on three datasets (plastome data, ITS sequences, haplotypes) estimated origin divergence time plants highly similar, their structure features conserved. possessed high significant lineage geographic structure, may associated with long-term history, complex terrain habitat, sexual reproduction mode. originated late Eocene (36.03 Ma), closely related early uplift Qinghai-Tibetan Plateau (QTP) Hengduan (HDM). diversification occurred Oligocene (25.43 largely influenced by colonization available climate terrain. results showed clustered into a separate clade nested within Cyclorhiza. waltonii sister peucedanifolia, puana purpureovaginatum.
