In this study, morphological, anatomical and micromorphological properties of Onosma armenum DC. (Boraginaceae) were investigated. Morphologically, it was observed that the species have a perennial root system. Anatomically, the cross sections of the root, stem and leaf and the surface sections of leaf were examined. The anatomical properties of root, stem and leaf were determined. It is found that leaf is isobilateral and amphistomatic. Stomata cells are anisocytic and anomocytic.The stomata index is 23.14 for the upper epidermis and 21.48 for the lower epidermis. The fruit surface of O. armenum is reticulate type and areolate
subtype. Trichome types are simple, porrect -stellate and glandular.
