To present detailed pharmacognostic study of the leaf of Clerodendrum splendens, an important plant in Indian system of medicine. Methods: The macroscopy, microscopy, physiochemical analysis, preliminary testing of the leaf of the plant for standardization was investigated. Results: The vascular tissues constitute a complex system of hollow wide cylinder of unequal thickness. The vascular bundles in the other regions of the cylinder are wedge shaped and collateral having a group of diffusely distributed xylem elements mixed with narrow fibres. The entire cylinder of vascular bundles contains a thin layer of fibres and elongated prismatic calcium oxalate crystals are sparsely distributed in the central ground tissue. The lamina is distinctly dorsiventral, the adaxial and abaxial sides are heteromorphic. Short stalked peltate type of glandular trichomes is located in shallow epidermal pits. Conclusion: It can be concluded that the pharmacognostic profile of leaf of Clerodendrum splendens is helpful in developing standards for quality, purity and simple identification.
