Abstract
This paper investigated transverse sections of stems and leaves of seven species belonging to the genus Ipomoea of the family Convolvulaceae collected from Khartoum state, Sudan. They are Ipomoea cairica (L.) Sweet, Ipomoea aquatica Forssk, Ipomoea pes-caprae (L.) R. Br., Ipomoaeverticillata Forssk., Ipomoea eriocarpa R. Br., Ipomoea triloba L., and Ipomoea carnea Jacq. The study revealed that certain features were of significant importance in separation of these taxa. The vertically arranged rows of secretory canals separated I. pes-caprae from the other species in which they are solitary arranged. Also presence of striated stem cuticle separated I. carnea from the other species which show thin entire cuticle. Hollow pith characterizes I. aquatica while the presence of crystals in the pith characterizes I. triloba. Two species: I. cairica and I. eriocarpa are characterized by the presence of sunken glandular hairs on their leaves. I. cairica and I. eriocarpa were differentiated according to their cambium activity, which was equally active in I. cairica but not in I. eriocarpa. Laterocytic type of stomata is the common feature among all the studied species
