Comparative Anatomical Studies of Two Species of Talinum occurring in South West, Nigeria.

Anatomical studies was carried out on Talinum triangulare (Jacq.) Willd and Talinum paniculatum (Jacq.) Gaertn. Talinum triangulare was collected at Adeyemi College of Education, Ondo city, Ondo State, Nigeria with coordinates 7.07 07ºN, 4.81 84ºE while Talinum paniculatum was collected at Joseph Ayodele Babalola University, Ikeja Arakeji, Ilesa in Osun State, Nigeria with coordinates 7.30 00ºN, 4. 49 00ºE. Widens of T. paniculatum were collected and established in buckets in Ondo city, Ondo State, Nigeria. At flowering, the leaves were collected for anatomical studies. Epidermal studies of the leaves of two species of Talinum was carried out in a bid to exploit the characters that would be of diagnostic values. Free hand peeling was done for leaf portions that were used for epidermal studies. Leaves were cleared for venation using standard methods and observations were made with compound light microscope. Anatomical observations made from this study revealed diagnostic characters that can be used for the identification of each of these species. The study revealed that the leaves are amphistomatic, stomata is more abundant on the abaxial surface, laterocyclic. Sclereids and druses were observed. The two species can be distinguished based on the anticlinal walls on the adaxial surface which is straight to slightly undulating and presence of unicellular non-glandular trichomes associated with the abaxial surface of T. paniculatum.
