Abstract

Foliar epidermal studies were conducted on ten species in the family Sterculiaceae in search of stable taxonomic characters that could be employed in order contribute to their classification and identification.

In spite of the remarkable morphological differences, the results indicated that the species are relatively uniform in their quantitative macromorphological characters except for the leaf shape and base which varied from elliptic, lanceolate to palmate and leaf base from cordate, obtuse to cunneate.

The epidermal characters such as number of cells, anticlinal wall pattern, cell wall thickness and the stomata size varied among the species.

The epidermal cells varied from polygonal to irregular while the anticlinal walls varied from straight to straight\curve and slightly curved. All the species except Cola nitida (Vent) Schott, Malachanta alnifolia (Bak) Pierre, Mansonia altissima (A.Chev) R.Capuron, Theobroma cacao Linn and Waltheria indica Linn are amphistomatic.

Stomata types included anisocytic in T. cacao, laterocytic in C. hispida, anomocytic in C. millenni Schum, staurocytic in C. nitida and paracytic in W. indica, M. altissima and Malacantha alnifolia.

ABSTRACT

Investigation on the leaf epidermal morphological features was carried out on five species of the genus Capsicum in the family Solanaceae collected from different regions in the Southwestern part of Nigeria in search of taxonomic and diagnostic characters that could be employed for their classification and identification.

The species are C. annuum L., C frutescens L., C. chinense Jacq., C. baccatum L., and C. chacoense Hunz. All the species possessed either anomocytic or anisocytic stomata type on both adaxial and abaxial surfaces except for C. chinense which showed paracytic stomata type on both surfaces.

The leaves of C. baccatum, C. annuum, C. chinense and C. frutescens are amphistomatic, while that of C. chacoense are epistomatic.

The similarities and overlaps observed in the cell shape, stomata index and anticlinal wall pattern of the species provide evidence for their genetic and evolutionary relationship and justification for their taxonomic grouping.
