Fourteen taxonomic characters have been studied in three wild plant species in El-Riyadh city; Francoeuria crispa, Zilla spinosa and Rumex vesicarius; collected from three different habitats. The results of this study revealed that the habitats have insignificant effect on the leaf characters in spite of the slight effect on the general status, fruiting stage and color of the plants. Cross correspondence analysis between the habitats revealed that the variations were within the confidence limits. It is concluded that leaf characters can be used as an effective selection criterion for classification.
