The Significance of Cuticular Features, Petiole Anatomy and SDS-PAGE in the Taxonomy of the Lauraceae
E. A. Kamel and M.H. A. Loutfy

Abstract: SDS-PAGE of seed protein, petiole anatomy and leaf cuticular features were used to re-assess the taxonomic relationships between eight taxa presenting four genera of the Lauraceae, viz.Apollonias Nees (one species), Cinnamomum Schaeff (three species), Laurus L. (two species) and Persea Mill. (one species with two varieties). The data obtained were analyzed by Ntsys-pc program package using the UPGMA clustering method. The produced dendrograms were discussed. SDS-PAGE analysis showed a close relationship between Apollonias and Persea. Domatia and certain unique features were recorded in the leaf epidermis of Apollonias. Considerable variations were evident between the two varieties of Persea and a re-evaluation of their status was suggested. The validity of SDS-PAGE of seed protein criteria in the Lauraceae was confirmed.
