Present investigation deals with the pharmacognostic studies of some medicinally important species of Curcuma L. namely Curcuma amada Roxb., Curcuma aromatica Salisb., Curcuma caesia Roxb., Curcuma longa L. and Curcuma zedoaria (Christm.) Roscoe. Distinct variation was observed during foliar epidermal micromorphology study. Epidermal cell shape was found distinctly variable though cell wall outline was found to be straight in all the selected species. Leaves of the investigated taxa were found to be amphistomatic and the stomata are of tetracytic type. Stomatal index ranges from 13.54 (Curcuma longa) to 3.25 (Curcuma zedoaria). Trichomes were found to be present on both the epidermal surfaces of all the investigated taxa except Curcuma caesia where trichomes were found to be restricted to the upper epidermal surface. Petiole outline is almost concavo- convex in T.S. and the number of vascular bundle were ranges from 57 (Curcuma longa) to 39 (Curcuma caesia). Colour of the powdered crude drug varies from colourless to bright yellow. Textures of the fresh powders were smooth and fibrous. Moisture content ranged from 8.02 % (Curcuma longa) to 14.53 (Curcuma amada). Total ash value ranged from 3.91% to 5.49%. Microchemical colour reaction test of the ethanolic plant extracts showed the presence of important phytochemical groups like- alkaloids, flavonoids, proteins, saponins reducing sugars etc.
