Introduction: Pellionia heyneana Wedd. Leaves have long been employed as a traditional remedy by the Cholanaikan tribe of South India to treat various ailments. Methods: Pharmacological and physicochemical evaluation of P. heyneana leaf has been carried out to determine its macro and microscopic characters, and also some of its quantitative characters as per standard procedures. Results: The pharmacognostical evaluation of P. heyneana leaves revealed the presence of characteristic microscopic features of the crude drug like cystoliths in upper epidermis, helicocytic stomata in lower epidermis, large number of peculiar shaped, huge (200-400 m) foliar sclereids, absence of palisade tissue in the lamina etc. Powder microscopy showed the presence of calcium oxalate crystals, stone cells, multicellular trichomes, resinous blocks, spiral vessels, xylem fibre, starch grains, simple fibre etc. Conclusions: All the parameters evaluated in the study will aid to identify the authenticity of P. heyneana leaf even from the crushed or powdered form.

Introduction: Ingeneral, members of Cucurbitaceae are well exploited for their medicinal, economic and culinary values, however few of them are less exploited. The present study deals with pharamcognostical evaluation of one such plant namely Kedrostis foetidissima (Jacq.) Cogn.called as Appakovai in Tamil. Methods: Pharmacognostic evaluations were carried out by organoleptic evaluation, anatomical studies and powder microscopy of leaves, roots and root tubers. Results: Organoleptic evaluation revealed that the characteristic white tubers, as storage organs, leaves exhibited a foetidodour when crushed. Anatomy of leaves showed lithocysts and anomocytic stomata, root showed the presence of fissured periderm and cleaved vascular bundles and that of root tubers showed 3 or 4 exarch xylem. Powder microscopy of root tubers showed narrow and wide fibers; long, narrow and drum shaped vessels and scattered sclereids. Conclusion: The present Pharmacognostic and Powder microscopic studiesreveals that, the characteristic features of this plantparts resembles, the other members of cucurbitaceae.
