The genus, Capsicum belongs to the family Solanaceae. The transverse sections of the root of five varieties of Capsicum species were investigated. Some common similarities in the pores, ray sizes showing multiserriate and apotrachael parenchyma in some varieties shows close affinity .Variations in the number of vessels and scanty vasicentric paratracheal are suspected to be an influence both by the environment and ecological adaptation as well as genotype. Possession of banded and ,aliform./transverse paratracheal parenchyma by var. Bird eye pepper’ and var. ‘Nsukka yellow pepper’ indicates the two varieties to be more primitive when compared with others .Thus, this research could be important to plant Taxonomist in solving the confusion in the taxonomy of cultivated Capsicum.
