Abstract: A Foliar anatomical study of five Kalanchoe species in Nigeria was carried out for taxonomic purposes. The study tends to provide anatomical information on Nigerian Kalanchoe species, for the purpose of documentation and delimiting the taxa studied. Matured fresh samples of the leaves of Kalanchoe crenata (Andr.) Haw, Kalanchoe gastonis-boonieri Raym.-Hamet & H.Perrier , Bryophyllum pinnatum (Lam.) Oken, Bryophyllum delagoense (Eckl. and Zeyh.) Schinz, Bryophyllum houghtonii (D.B Ward) P.I.Forst were used. Epidermal peels and transverse sections were carried out according to standard procedures. Unifying and diagnostic characters important for the taxonomy of the selected five species of the genus Kalanchoe were identified. Unifying characters include amphistomatic leaves, a non-pitted anticlinal wall, mesophyll not differentiated into palisades and a spongy layer. Diagnostic characters such as uniseriate to multiseriate epidermis in Bryophyllum houghtonii. The study provides concise information on the anatomical attributes of the epidermis and transverse section of the leaf of the Kalanchoe species studied
