The genus Exochaenium (23 species) is endemic to sub-Saharan Africa, with species occurring in most tropical and sub-tropical regions of the continent, particularly on the Katanga plateau (Angola, Democratic Republic of Congo and Zambia), with many extending to the Sudano-Zambesian and Guineo-Congolian regions.[1][2] The genus is monophyletic[3] and is used to study the variation and evolution of herkogamy.[4]
