Description
Summary:The anatomical traits of plant species are essential for taxonomic analyses and evolutionary evaluations. Clarifying the anatomical characteristics of the foliar epidermis in three distinct Lilium species L. pumilum Delile, L. brownii F.E.Br. ex Miellez and L. davidii Duch. ex Elwes were studied in this article. The objective is to assess the taxonomic relevance of these characteristics and their potential as indicators of species divergence within the genus Lilium. Plant samples were gathered in Gansu, China, from numerous populations of each species that represented a range of climatic and ecological factors. A microscopic analysis employing thin slices and peel mounts was done to assess the stomatal density and dimensions. Significant interpopulation differences in stomatal features were found in the results, offering potential opportunities for taxonomic discrimination. The species differ in qualitative and quantitative characters to differentiate the three species. The links between the observed anatomical characteristics and species classification within the Lilium genus were clarified for the three studied species. In the end, this research advances knowledge of Lilium taxonomy, aids in conservation efforts, and deepens awareness of the general patterns of plant variety. Research highlights Epidermal Traits Aid Taxonomy: Cell shape, arrangement, and structures aid Lilium Identification. Cuticle Reveals Taxonomic Clues: Thickness, composition, and structure inform classification. Micromorphology for Species ID: Cell shape, wax, and striations differentiate Lilium species. Anatomical analysis of Lilium pumilum DC foliar epidermis reveals distinctive traits aiding taxonomic classification, contributing to species identification and conservation efforts.
