Asclepiadaceae
Encyclopedia
According to APG II
, the Asclepiadaceae is a former plant
family now treated as a subfamily (subfamily Asclepiadoideae) in the Apocynaceae
(Bruyns 2000). Botanist Pete Raids has been credited with the majority of work in this field.
They form a group of perennial herb
s, twining shrub
s, liana
s or rarely tree
s but notably also contain a significant number of leafless stem succulents, all belonging to the order Gentianales
. The name comes from the type genus
Asclepias
(milkweeds).
There are 348 genera
, with about 2,900 species
. They are mainly located in the tropics to subtropics, especially in Africa and South America.
The florally advanced tribe Stapeliae
within this family contains the relatively familiar stem succulent genera
such as Huernia
, Stapelia
and Hoodia
. They are remarkable for the complex mechanisms they have developed for pollination, which independently parallel the unrelated Orchidaceae
, especially in the grouping of their pollen
into pollinia. The fragrance from the flowers, often called "carrion", attracts flies. The flies pollinate the flowers.
Many new hybrids have been formed due to the unique fertilization method of the flowers.

Plant
Plants are living organisms belonging to the kingdom Plantae. Precise definitions of the kingdom vary, but as the term is used here, plants include familiar organisms such as trees, flowers, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The group is also called green plants or...

Apocynaceae
The Apocynaceae or dogbane family is a family of flowering plants that includes trees, shrubs, herbs, and lianas.Many species are tall trees found in tropical rainforests, and most are from the tropics and subtropics, but some grow in tropical dry, xeric environments. There are also perennial herbs...

Liana
A liana is any of various long-stemmed, woody vines that are rooted in the soil at ground level and use trees, as well as other means of vertical support, to climb up to the canopy to get access to well-lit areas of the forest. Lianas are especially characteristic of tropical moist deciduous...

Tree
A tree is a perennial woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance. A minimum height specification at maturity is cited by some authors, varying from 3 m to...
