The 100 species are endemic to South Africa, found mainly in the Western Cape but also in Northern and Eastern Cape.

Most of the species are pollinated by generalist pollinators such as bees and monkey beetles (Hopliini). The pale pink, long-tubed flowers are pollinated by long-proboscid flies (Tabanidae and Nemestrinidae) (Goldblatt & Manning 2000).
