About 73 genera and 1605 species (warm temperate
and tropical regions worldwide), of which 21 genera and 263 species native to southern Africa (the region with the highest
diversity of amaryllids in the world). An additional three genera and four species
are
naturalised, and an additional 13 genera and 43 species are cultivated in southern Africa.
Genera native to southern Africa
List from Snijman (2000), Meyer (2000) and
Plants
of Southern Africa - an Online Checklist (SANBI).
Agapanthus
Six species, all endemic to southern Africa. Previously placed in the
Agapanthaceae. |
 |
Allium
There are about 550 species worldwide, most of them
occurring in the northern hemisphere. Allium dregeanum is the only
species thought to be native to southern Africa although there is some doubt
that it originates here. Allium triquetrum (Three-cornered leek) is
naturalised in the region and an additional 12 species are cultivated,
including leek,
onion, shallot,
chives
and garlic. Previously in Alliaceae. |
 |
Amaryllis
Two species, endemic to the Northern Cape
and Western Cape, within the winter-rainfall region. |
 |
Ammocharis
Seven species, native to sub-Saharan
Africa, with six species native to southern Africa. |
 |
Apodolirion
Six species, all endemic to southern
Africa. |
 |
Boophone
Two species, both native to southern Africa.
Boophone disticha is widely distributed in sub-Saharan Africa. |
 |
Brunsvigia
Eighteen species, all endemic to southern Africa. |
 |
Clivia
Six
species, all endemic to southern Africa. |
|
Crinum
About 65 species worldwide, found
mainly in the tropics, with 22 species native to southern Africa. An
additional four exotic species are cultivated in the region. |
 |
Crossyne
Two species endemic to
the winter-rainfall regions of the Western Cape and Northern Cape, in South
Africa. |

usually enough to cause death if eaten. Twenty-four species, all endemic to southern Africa. |

the Mediterranean region, southern Asia, the Canary Islands and Africa.
Pancratium
tenuifolium is the only species native to southern Africa, found in

|
Nothoscordum
There are 18 species
worldwide, found mainly in the Americas.
Nothoscordum
x borbonicum is an introduced weed in southern Africa, often found
growing in garden lawns and along roads. It is difficult to control because
the parent plant produces many small bulblets which get left behind when the
plant is pulled out. Previously in Alliaceae. |
 |
Zephyranthes
Zephyranthes
grandiflora originates from Central America and has become established
in coastal areas of KwaZulu-Natal. An additional four species are cultivated
in southern Africa. |
|
Other genera, cultivated in southern Africa
List from Glen (2002). The species name is listed for
genera with only one species recorded in southern Africa. Doryanthes now included in
Doryanthaceae in the order Asparagales.
