In this study, the anatomical, micromorphological and karyological features of Rindera cetineri Yıldırım (Boraginaceae), an endemic species in Denizli, were investigated. In anatomical studies, cross sections for root and stem measurements, and cross and superficial sections for leaf measurements (base and stem leaf) were taken. The stomatal index was calculated by counting the stomata and epidermis cells on the upper and lower surfaces of the superficial sections taken from the leaves. In micromorphological studies, pollen type and surface ornamentation, seed shape, and surface ornamentation were determined. The pollen type of R. cetineri is 6-heterocolpate, the pollen shape is prolate-spheroidal, subprolate and the surface ornamentation is microgranulate. As a result of the karyological study, the somatic chromosome number of R. cetineri was determined as 2n=24.
