This paper deals with the pharmacognosy of Hyptis suaveolens leaf including its morphological, anatomical, chemical constituents and powder analysis. Contrary to earlier reports, the leaves are amphistomatic. Stomata are diacytic, a few being isotricytic and ansiotricytic. Four types of trichomes have been noted. The venation is semicraspidodromous. Midrib consists of one large moon shaped and petiole with four wedge-shaped vascular bundles. Powder microscopy revealed fragments of epidermis, mesophyll, trichomes and tracheary elements. Positive tests for glycosides, polyphenolases, flavones and juglones are also recorded.
