Distribution of Caesalpinia based on quality-controlled digitised herbarium records. The distribution of Caesalpinia pulcherrima in Sonora and Guatemala is based on specimen records that morphologically appear to be non-cultivated, but the exact native distribution of the species remains difficult to ascertain because it has been widely cultivated for a long time. See Suppl. material 1 for the source of occurrence data.
