¹SDTF – Seasonal Dry Tropical Forest;
Populations sampled with their identification code (ID), elevation above sea level, habitat description and sample size, analysed for nuclear and plastid markers in Epidendrum cinnabarinum (C) and E. secundum (S) from Northeast Brazil, distributed in the Caatinga (CAA) and Brazilian Atlantic Forest (BAF) biomes. Populations are indicated as shown on the maps in Figure 1A and B.
