Leaf anatomy and morphology were studied in 11 tree species growing in an undisturbed forest and the adjoining fynbos for over 50 years. Functional anatomical results suggest that the forest and the fynbos are ecologically distinct. Moreover, leaf anatomy suggests that the foliage is primarily adapted for photosynthesis rather than for control of transpirational water loss. Forest precursor tree species and scrub species exhibit xeromorphy in the fynbos whereas they exhibit mesomorphic features inside the forest. The wide-ranging species, such as Olea capensis subsp. capensis, simulated the response of the forest precursors, with the cuticle being phenotypically plastic between the forest and the fynbos but not between the stream and non-stream habitats. Finally, the forest precursors, the scrub species, and the wide-ranging taxa seem to have anatomical characters which can be modified in the fynbos and therefore allow its colonization by a variety of different species.

Key words: Leaf anatomy, phenotypic plasticity, xeromorphy, morphological adaptation, habitat.
