The family in the composition represented here is considered
paraphyletic. Three genera and 41 species are native to southern Africa
and a further genus and two species are naturalised in the region.
Genera native to southern Africa
Talinum
has been moved to the Talinaceae in the
Caryophyllales.
Ceraria and
Portulacaria have
been moved to Didiereaceae
in keeping with the classification on the
Angiosperm Phylogeny Website. Anacampseros and Avonia
evidently need to be taken out of Portulacaceae in order to
prevent the family from being paraphyletic but a family has not yet
been designated for holding these genera.
|
Anacampseros
Endemic to southern Africa, with the
17 species distributed mainly in arid and semi-arid areas. |
|
|
Avonia
Native to Somalia and southern Africa. Fourteen species
native to southern Africa, concentrated mainly in Namibia
and the Northern Cape. |
|
|

A cosmopolitan genus of 40 species, with 10
species native to southern Africa, particularly in arid areas, and a
further species that is naturalised in the region. |

Calandrinia
The 12-15 species are native to North and South
America; Calandrinia ciliata, has become
naturalised in the Western Cape. |
