Popis:	A study was carried out on the leaf epidermal of seven varieties of Vigna unguiculata (L.) Walp, family Fabaceae cultivated in Awka, Anambra State Nigeria. Leaves of the plants were assessed for their phylogenetic relatedness through diagnostic epidermal studying of the cell shapes, anticlinal wall types and stomatal characteristics at the abaxial and adaxial surfaces. The cell shapes, anticlinal wall types and the stomatal characteristics revealed some correlations among the studied taxa. All the seven varieties possess stomata on both the abaxial and adaxial surfaces signifying amphiostomatic. The distribution of the stomata varies and no variations were observed in the cell wall, contours and thickness. Stomata distribution was more on the abaxial layer than the adaxial layer and was mainly paracytic. Features of the quantitative morphology as the stomatal index (SI) were detailed in this study. Result of the epidermal features of the studied taxa revealed their intraspecific relationship and some diagnostic characteristics that could be used for taxonomic decision.
