Distribution

Asia-Tropical: Australasia: Cape Province: present Madagascar: present S. Papua New Guinea: present South Africa: present W. Distr.: Wassi Kussa area: present
Madagascar (1 sp.), South Africa (2 spp.; Cape Province) and Australia (7-9 spp.), of which one species also occurs in Malesia: S. Papua New Guinea (W. Distr.: Wassi Kussa area).

Notes

Generically this group is regarded as well-defined by the spirally-twisting perianth and 2-ovuled locules. The South African monotypic genus Nanolirion Bth. (1883) was formerly distinguished by having a 1-3-flowered inflorescence (Phillips, 1951), but Obermeyer (1973) placed it under Caesia.
