The paper deals with a detailed investigation on the leaves of Aristolochia bracteolata Lam. which includes it’s morphological, anatomical and powder analysis. The leaf is amphistomatic, with tetracytic, anomocytic and anisocytic stomata. The leaf adaxial surface has unsinate hair, which is a significant character for identification of this plant. Lamina bifacial. Ground tissue of midvein consists of collenchyma and parenchyma tissues. Hypodermal collenchyma is present as a group of cells in the adaxial ridge and is 2-3 layered on the abaxial side. Parenchyma beneath the collenchyma with small intercellular spaces is present. Midvein consists of one large oval shaped v.bundle at the centre. In T.S., petiole is semilunar, adaxially flat with 5 vascular bundles, arranged in an arc.
