FOLIAR ANATOMY AND MICROMORPHOLOGY OF 11 SPECIES OF EUGENIA L (MYRTACEAE)

The anatomy and micromorphology of eleven species of Eugenia found in the 'restinga' of Marica, Rio de Janeiro, Brazil, were studied and com pared. The characteristics found to be of most use in distinguishing t he species are: presence and types of trichomes persistent in the adul t material, form and arrangement of overlying cells (epidermal cells o ver secretory cavities), pattern of anticlinal walls of epidermal cell s (primary sculpturing), occurrence of epicuticular striae and folds ( secondary sculpturing) and presence of peristomatal folds. An analytic al key based on these characteristics is presented for the Eugenia spe cies studied.
