Abstract


Many species of Vitex have medicinal values and despite of being widely
utilized, they are sometimes confusing due to high morphological variation. In this study, leaf anatomical characters of three species, V. pinnata, V. negundo and V. trifolia have been studied comprehensively including the epidermal characters, margin TS, lamina TS, midrib TS and petiole TS. Leaf morphological observation was also conducted. Generally, all three species show similar anatomical characters. However, some anatomical variations can be diagnostic and taxonomically valuable. Morphological characters for the leaf apex and lamina can also be used in delineating these three species.
