In China, the genus Tulipa L. has been identified as a national second-class protected plant. Due to complex evolutionary and genetic backgrounds of tulips, taxonomy its species remains matter dispute. The current study is dedicated clarifying taxonomic relationship between two closely related species, T. iliensis thianschanica, by integrating morphological, karyotypic, molecular evidence—a novel framework for resolving ambiguities in species. Morphological analyses showed significant differences filament shape, pistil length, overall plant height, presence or absence stem hairs, perianth length width, which supports conclusion that they are distinct (p < 0.001). Karyotype analysis further verified disparities their chromosome morphology, karyotype indices scatter plot distributions suggest Molecular phylogenetic using Internal Transcribed Spacer sequences (ITSs) chloroplast genomes confirmed there evidence indicating possible occurrence hybridization events. research findings demonstrate thianschanica independent thereby providing valuable insights into wild tulips contributing conservation these
