Thisresearch was aimed to explore the morphological and anatomical features of Monotheca buxifolia (Falc.) A. DC. (Sapotaceae) fruit, seed, leaf and barks of stem and root. The berry fruit of M. buxifolia has a single seed with ruminate endosperm and horizontally curved embryo. The simple bifacial leaf is covered by a single layer of upper epidermis followed by double layered palisade parenchyma with a ratio of 6.75± 0.5 to the epidermal cells. Lower epidermis is thoroughly furnished with simple and forked trichomes. The reticulate venation of leaf formed a vein islets number of 37.4±2.88 per mm2 and vein termination number of 35.4±1.8 per mm2. The stephanocytic stomata of leaf had a stomatal density of 77.4±3.57 per mm2 on lower epidermis while the stomatal density on upper epidermis was comparatively very low i.e. 7.75± 0.97 per mm2. The lower and upper epidermis had a stomatal index of 10.53±0.40 and 5.39±0.33 respectively. Stem and root bark show a characteristic arrangement of tissues. These features of M. buxifolia are important in tracing its taxonomic and phylogenetic affiliations, standardization and for pharmacognostic evaluation.
