Fig. 1From: Differential gene expression reveals mechanisms related to habitat divergence between hybridizing orchids from the Neotropical coastal plainsDistribution and sampling of Epidendrum fulgens, E. puniceoluteum and their hybrids. a Geographic distribution of Epidendrum fulgens and E. puniceoluteum in the Atlantic coastal areas. b Sampled populations in allopatry (blue for E. fulgens, orange for E. puniceoluteum) and sympatry (in black). BER = Bertioga - SP; ICO = Ilha Comprida - SP; ICA = Ilha do Cardoso - SP; PPR = Pontal do Paraná - PR. c Typical microhabitat in which each parental species occur: sand dunes for E. fulgens, sedge swamps for E. puniceoluteum.
