In the present research, anatomical, palynological and micromorphological characteristics of three endemic Bellevalia species (B. gracilis, B. malatyaensis and B. vuralii) for Turkey are carried out. This work reveals the descriptive characteristics of the examined species, and contribute to solving taxonomic problems. Anatomical studies were carried out on cross sections of root, scape and leaf. The metaxylem, the number of root cortex cells, and the number of cortex and sclerenchyma cells in the scape were found to be significant in terms of taxonomy. Pollen grains of all the examined species were monosulcate and heteropolar. In addition, seed and pollen surface ornamentation were photographed under SEM microscopy, which SEM micrographs showed that the exine sculpturing pattern is reticulate-perforate, and pollen muri walls of were different among the examined species. Conversely, seeds showed a general similarity of the surface among the studied species, all showing a reticulate faveolate ornamentation.
