(Olacaceae) are edible and used for cure of headache. A detailed pharmacognostical character of its leaf is lacking. In the present study, its leaves evaluated for their morphological, microscopical and quantitative microscopic characters following standard procedures. The overall study showed the leaves are 3.5–9 × 2.5–3.2 cm in size, reticulate venation, petiole 0.2–0.5 cm. Leaves showed the presence of trichomes, collenchyma, and vascular bundles. Powder microscopy of the dried leaves shows paracytic stomata of lower epidermis, epidermal cells of upper epidermis, and unicellular trichomes of epidermis, rosette and prismatic crystals of calcium oxalate. KEY WORDS: Olax scandens, microscopy, quantitative methods, stomata.
