Leaf morphology of 89 tree species from a lowland tropical rain forest (Atlantic forest) in South Brazil
We examined the leaf morphology and anatomy of 89 tree species growing in an area of coastal Atlantic Forest in South Brazil. The majority of the species (> 75%) had small (notophyll and microphyll) elliptical simple leaves with entire margins. These leaves presented a typical anatomical structur...

| description | We examined the leaf morphology and anatomy of 89 tree species growing in an area of coastal Atlantic Forest in South Brazil. The majority of the species (> 75%) had small (notophyll and microphyll) elliptical simple leaves with entire margins. These leaves presented a typical anatomical structure consisting of a single epidermal cell layer, single palisade parenchyma cell layer, and spongy parenchyma with 5 to 8 cell layers. The sclerenchyma was limited to the vascular bundles. The majority of the tree species (91%) had leaves with mesomorphic characteristics. Few species depicted leaves with xeromorphic features as would be expected in such oligotrophic sandy soil. These mesomorphic features appeared to be associated to high efficiency mechanisms for nutrient cycling that compensated for the low nutrient content of the mineral soil.<br>Este estudo examinou a morfologia e anatomia foliar de 89 espécies arbóreas de uma área de Floresta Atlântica Litorânea no Sul do Brasil. A maioria das espécies (>75%) possuem folhas pequenas (notófilas e micrófilas) elípticas e simples com margens inteiras. Essas folhas apresentam uma estrutura anatômica formada por epiderme uniseriada, parênquima paliçádico composto por um único estrato de células e o parênquima esponjoso composto por 5 to 8 estratos celulares. O tecido esclerenquimático é limitado aos feixes vasculares. A maioria das espécies arbóreas (91%) possui folhas com características mesomórficas Poucas espécies (9%) são xerófilas como era esperado em florestas que crescem sob solo arenoso oligotrófico. As características mesomórficas parecem estar associadas a eficientes mecanismos de ciclagem de nutrientes que compensam o baixo conteúdo de nutrientes do solo mineral. |
