Abstract :In this study, the anatomical, palynological and karyological properties of Verbascum weidemannium Fisch. & Mey. growing around Sivas in Anatolian part of Turkey were investigated for the first time. As a result of root and stem anatomy studies showed that both organs are in secondary structure. Cambium consists of 2-3 cell layer in root and 2-4 cell layer in stem. Leaves have dendroid hair on both surfaces. According to mesophyll layer leaf is bifacial. Stomata are anomositic and located on both surface. Sepals have dendroid hairs on both surface and have 7-11 cell layered chlorenchyma. Petals are covered single layered papillose cubic and rectangular epidermis cells in upper surface and nonpapillose cells in lower surface. The filament is approximately triangular shaped in crooss-section and vascular bundle is concentric-hadrocentric. Pollen grains of V. wiedemannianum are tricolpate, oblate-spheroidal; P/E ratio is 0.98 and exine ornamentation is reticulate.
