英文摘要	In seasonally dry tropical forests such as the Brazilian Caatinga, factors such as soil type and luminosity are known to cause changes in foliar tissues that enable the survival of species in such places. The present study aimed to describe the leaf morphoanatomy of Senna cana and to observe the plasticity in leaf tissues receiving both direct and indirect light radiation. The study was carried out in the Catimbau National Park in Buique, PE, Brazil. Mature leaf samples were collected from under full sunlight and full shade in three areas with soils of different colors. Histological slides were prepared for visualization of epidermal faces, internal leaf structure, and histochemical tests. Plasticity was noted in the type of trichome that covered the epidermal faces, and in the number of layers of the palisade and spongy parenchymas, even under the indirect effect of radiation. Phenolic compounds and lipids also showed plasticity. These results demonstrate that Senna cana is a species with high plasticity for the luminosity factor. Further, it was noticed that indirect light also promotes anatomical changes and should be considered in future analyses.
