Distribution map of Epidendrum fulgens and E. puniceoluteum based on field collection and herbarium material, and location of the populations studied. a Yellow, red, and purple circles indicate the presence of E. fulgens, E. puniceoluteum, and hybrids, respectively. Outlined circles indicate significant FSGS. b Schematic representation of a transect from the beach to inland, indicating the habitats where E. fulgens, E. puniceoluteum, and hybrids occur.
