The present research work was done to evaluate the anatomical differences among selected species of family Bignoniaceae, as limited data is available for this in Pakistan. Bignoniaceae a remarkable its various medicinal properties and characterization an important feature identification classification plants. In study, several structures were examined, including stomata type shape, leaf epidermis epidermal cell size, presence or absence trichomes crystals (e.g., prisms, raphides, druses). Three statistical tools-heat map analysis, correlation principal component analysis (PCA)-were used highlight distinctions similarities species. On both upper lower surfaces, polygonal, irregular, hexagonal cells with thick walls observed. patterns anticlinal detected: curved, straight, sinuous. Distinct stomatal types also identified across different For instance, sunken observed Kigelia africana Jacaranda mimosaefolia, while anomocytic found Oroxylum indicum, Pyrostegia venusta, Tecoma stans, Tecomella undulata, Mansoa alliacea, Heterophragma adenophylla, Handroanthus impetiginosus, Campsis radicans, Anemopaegma chamberlaynii. Paracytic examined B. callistegioides Dolichandra unguis-cati. Tabebuia aurea only Tetracytic stomata. A contiguous Millingtonia hortensis. This contained three trichomes.
