Anatomical study of vegetative parts and Powder microscopy of Cordia myxa L. (Boraginaceae) in Iraq

Abstract

Abstract-This study deals with the anatomical features of Cordia myxa stem, leaf and petiole in Iraq. Peeling method have been clarified anomocytic stomata with anticlinal walls of epidermal cells, the cross sections of lamina shown the unicellular epidermis in abaxial and adaxial surface, unicellular trichomes spread in the epidermis. adaxial covered by thick cuticle, bifacial mesophyll. idioblasts spread through palisade parenchyma, oval to circular shape cells of spongy parenchyma, midrib have large concentric vascular bundle is present at the midrib region and one vascular bundle in above. Petiole shape is square with five vascular bundle appear, the big one located on the central and four vascular bundle located in the corners. The dried leaf powder was brown to green in color, microscopy of the powder showed fragments of unicellular trichomes, stomata, fibers, crystal differ in shape like as regular prismatic, druses, sand crystal, and dendritic crystal like as snowflake formation in shape
