Background: Cassiamimosoides L. is one of the nonclassical folklore plants of Gujarat, known as Aval ni jaat. Root and leaves of this plant are used in diarrhea, wound healing and mouth ulcers by tribal people.
Aims and objectives: Review revealed that the leaf part of this plant are unexplored from the pharmacognostical aspects. Hence, the present study focuses on the pharmacognostical study of leaf along with its powder.
Materials and methods: Collection, macroscopy and microscopy have been carried out as per standard protocol.
Observation and results: The leaves are alternate, compound with opposite glabrous leaflets. T. S. of rachis consists of epidermis, pericycle and vascular bundle. T. S. of dorsiventral leaflet shows epidermis and vascular region with 1/5 palisade ratio. Leaf powder is dark green in color. Palisade parenchyma cells, rhomboidal crystals and unicellular warty trichomes are present in the powder of leaf.
Discussion: Yellow pentamerous flowers and paracytic stomata are key characteristics of genus Cassia. The value of stomatal index always remains constant even in different environmental conditions which play a very significant role in the identification of plant.
Conclusion: Microscopy of leaf and its powder of Cassia mimosoides can be helpful in identifying the plant in powder form and the values can be helpful in further standardization.
