Abstract

Foliar epidermal characters of ten species from the genus Cassia L. Emend. Gaertner, Senna Miller and Chamaecrista Moench found in South Western Nigeria were studied. The aim was to establish some useful diagnostic features that may be employed in combination with other characters as intra or inter-specific or generic tools for their delimitation. Our results revealed exciting features that are helpful in the identification of each species. These include guard cell area, stomatal index and frequency, presence or absence of trichomes, types of trichomes, as well as their length on epidermal surfaces and wall types. These results, therefore suggest diagnostic features that were found on the epidermal surface that can be employed to justify the separation of the new genera Senna and Chamaecrista from their initial genus Cassia.
