Myrcia splendens (Sw.) DC. is a native and endemic species of Brazil. Plants can have ecological plasticity due to environmental influences and studies on the ecological anatomy of leaves in the genus Myrcia DC. are scarce. In this sense, the present study aimed to verify the effect of seasonality and luminosity on the leaf morphoanatomical characteristics of Myrcia splendens (Sw.) DC., in order to contribute w...
