Aizoaceae
Encyclopedia
The Family Aizoaceae or Ficoidaceae (fig-marigold family or ice plant family) is a taxon of dicotyledon
ous flowering plants containing 135 genera and about 1900 species. They are commonly known as stone plants or carpet weeds. Species that resemble stones or pebbles are sometimes called mesembs. Several species are known as ice plant
.
of 2003 (unchanged from the APG system
of 1998) also recognises the family, and assigns it to the order Caryophyllales
in the clade core eudicots. The APG II system also classes the former families Mesembryanthemaceae Fenzl (1836) , Sesuviaceae Horan. (1834) and Tetragoniaceae Link (1831) under the family Aizoaceae.
Most species (96 %, 1782 species in 132 genera) in this family are endemic to arid or semi-arid parts of southern Africa
, but a few are from Australia
and the Central Pacific. Most of these species are succulents and belong to the subfamilies Mesembryanthemoideae and Ruschioideae and are loosely termed mesems or mesembs.
Most fig-marigolds are herbaceous
, rarely somewhat woody, with stems
growing either erect or prostrate. Leaves
are simple, opposite or alternate, and more or less succulent with entire (or rarely toothed) margins. Flower
s are perfect in most species (but unisexual in some), actinomorphic, and appear singularly or in few-flowered cymes developing from the leaf axils. Sepal
s are typically 5 (3-8) and more or less connate (fused) below. True petal
s are absent. However, some species have numerous linear petals derived from staminoides. The fruit
is a capsule
with one to numerous seed
s per cell.
A few species (especially Carpobrotus edulis, commonly called Ice Plant
) have been widely introduced
and become invasive.
Carpobrotus edulis was introduced
to California to stabilize soil along railroad tracks.
