Abstract

Seeds of six species of twelve accessions of miscellaneous legumes were obtained from the germplasm unit of the International Institute of Tropical Agriculture (IITA), Ibadan, Oyo State, Nigeria. The seeds were planted into plots of 5m long, spaced 1 meter apart at the botanical garden of the University of Agriculture, Abeokuta (UNAAB), Ogun State, Nigeria. Leaves of the plants were assessed for their genetic and phylogenetic relatedness through diagnostic epidermal studying of the cell shapes, anticlinal wall types and stomatal characteristics at the abaxial and adaxial surfaces. The cell shapes, anticlinal wall types and the stomatal characteristics revealed some correlations among the studied taxa. All the species were amphiostomatic possessing stomata on both the abaxial and adaxial surfaces. Proportions of the stomata distributions among the taxa were 75% (paracytic), 16.67% (anomocytic) and 8.3% (anisocytic) at both surfaces. There was no accession with diacytic stoma. Cell shapes were 75% polygonal, 25% irregular at the abaxial surfaces and 66.67%, 33.33% irregular and polygonal respectively at the adaxial surface. The prevalent anticlinal wall type was curved (41.67%) followed by curved/slightly straight (33.3%) and slightly straight (25%) at both surfaces. Result of the epidermal features of the studied taxa revealed some diagnostic characteristics that could be used for taxonomic decision
