Notes —See Gillespie (2007) for species description.

Although Sonder did not explicitly cite holotypes, his types based on Ecklon and Zeyher collections from South Africa are presumed to be housed in S ( Nordenstam 1980), with duplicates found in many other herbaria in Europe and Melbourne, Australia. Indeed, the specimen at Stockholm, which we consider the holotype, has the most abundant floral and fruit material and original labels.
