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.
