Has a strange distribution with five species native to southern Africa (one of which has a distribution extending into East Africa) and one species found on Lord Howe Island (east of Australia). The species found on Lord Howe Island is Dietes robinsoniana and is closely related to Dietes bicolor, found in the Eastern Cape. These two species have primitive characters for the genus (Goldblatt & Manning 2000).
