Abstract | ||||
Comparative studies have been carried out on the leaf epidermal features of six species (Handroanthus impetiginosus, Spathodea campanulata, Tabebuia aurea, Tabebuia rosea, Tecomaria capensis and Tecoma stans) of the family Bignoniaceae in Egypt. Observations were carried out and photographed by light microscope (LM). Epidermal features as shape of epidermal cells, pattern of anticlinal wall and presence or absence of stomata at both adaxial and abaxial sides of leaf were observed and compared between the taxa. The shape of epidermal cells varied between polygonal and irregular at both sides. The pattern of anticlinal wall was straight, straight to curved, curved and sinuous at adaxial side and straight to curved, curved, sinuous and wavy (undulate) at abaxial side. Stomata present at abaxial side of all species, while absent at adaxial layer of some species as S. campanulata and T. aurea. Species as S. campanulata and T. aurea are amphistomatic, while H. impetiginosus, T. rosea, T. capensis and T. stans are hypostomatic. | ||||
