ABSTRACT: Leaf and petiole anatomy of Pterygota species in Nigeria were studied and their distribution within the area is also reported, follow - ing outlined standard protocols. They are chiefly distributed in Southern Nigeria especially in wetter areas. Foliar micro-characters showed that the species are hypostomatic and generally paracytic, more abundant in P. berquaertii , with an average of 115/mm 2 , than in P. macrocarpa , where it is 59/mm 2 . Epidermal cells are irregular, rectangular and polygonal. Petiole spherical with uniseriate epi - dermis; cell distribution ranging from solitary to radial multiples. This study has provided valuable information about these indigen - ous species. Further systematic studies are vital to understand the number and timing of independent evolution of the species into Ni - geria.
