Abstract

Forty-two leaf epidermal features in 20 Nigerian species of Ficus, representing three of the four subgenera and four of the seven sections of the genus found in Africa have been examined. Discontinuities in these characters clearly separated the three subgenera studied, namely, Ficus, Sycomorus and Urostigma, and supported the earlier sectional classification of the subgenus Urostigma (i.e. sections Sycidium, Galoglychia and Urostigma). The subsectional boundaries among the members of the section Galoglychia studied, however, had little backing from their leaf epidermal characteristics due to extensive overlap of the features. The results of the present studies support the genetic basis of the qualitative and quantitative variations in the leaf epidermal cells, stomata and trichomes in the Nigerian Ficus and the present and potential applications of these features in diagnostic and taxonomic investigations in the genus are discussed.
