Abstract

A comparative anatomical studies of six G. hirsutum species collected from Katsina and Zamfara states of Nigeria were carried out. Stomatal complex types identified in three of the species were diacytic in the abaxial leaf surfaces and tetracytic in the adaxial leaf surfaces. Others had diacytic stomatal complex at the abaxial leaf surface as well as the adaxial leaf surface. Stomata were present on both leaf surfaces, that is the leaves were amphistomatic. Trichomes were found in 4 species out of the whole collection made. The abaxial leaf surfaces of the accessions had higher Stomatal density (up to 352.67mm-2) except in one (262.33mm-2). Stomata were relatively large in all the species. The epidermal cell shapes of all the species collected were polygonal.
