Abstract: Palisota hirsuta (Family Commelinaceae) is synonymously known as Palisota maclaudii and Dracena hirsuta. It is grown as an ornamental plant and a hedge. Ethnopharmacologically, the plant leaf and stem are used as an aphrodisiac, analgesic, antiseptic and in some cases used to treat gonorrhea. The present study was done to develop standardization parameters for the pharmacognostic identification of Palisota hirsuta. All parameters were established according standard procedure. The plant is a robust herb with a fleshy or woody rigid stem bearing soft brown hairs at the base. The leaves are arranged in rosettes with obovate to oblanceolate shape. Transverse sections of the midrib of leaf displayed a double layer of epidermal cells on the adaxial surface and a single layer of epidermal cells on the abaxial side. Powder microscopy of the leaves and stems revealed the presence of abundant acicular calcium oxalate crystals and starch grains. A number of spiral xylem vessels were also present. The ash values, solvent extractives and mineral content of P. hirsuta stem and leaves have also been established. Thus, the present studies has established parameters for the correct identification of P. hirsuta.
