Abstract
Verbascum is the one of the taxonomically difficult genus in the Scrophulariaceae family. The genus represented by 243 species with addition of 129 hybrids. 193 of them are endemic in Turkey. Especially Verbascum x splendidum is located in Turkey and Greece. In the present study, morphological, anatomical, palynological and seed properties of Verbascum x splendidum was investigated. According to results, in the anatomical study, the xylem elements were occupied a considerable area in the cross-section of root. The upper part of the epidermis cells in the stem cross-section was covered a distinct cuticle layer. The main vein of the leaf was shaped as bicollateral vascular bundle. Idioblasts weren't observed in the epidermis of the leaves. The seeds were dark brown coloured and prismatic-oblong shaped and alveolate surfaced. The Size of seeds were determined as 0.5-0.6 x 0.3-0.4 mm. Hilum was short and orbicular. The seed coat ornamentation was reticulate-rugose, and the pollen shape of V. x splendidum was subprolate. The shape of aperture was tricolpate, sculpture was tectate, and exine ornamentation was reticulate. In conclusion, in this study we were determined comprehensive morphological, anatomical, palynological and seed micromorphological of V. x splendidum.
