The morphology of the capsule, particularly the mode of dehiscence has traditionally been an important character for the classification of the Campanulaceae s. str., of which there are approximately ten endemic genera recognised in the South African region. Most of these are confined to the fynbos vegetation of the Western Cape Province. It is hypothesised that the edaphic conditions of the Western Cape, combined with very rugged topography and selection for highly specialised pollinators has contributed significantly to local speciation events and ultimately the evolution of these unique genera.
