The silk plant family (Asclepiadoideae), also called swallow root family, are a subfamily of the dog poison family (Apocynaceae).

Well-known representatives of this subfamily are the carrion flowers of different genera: Stapelia , Hoodia , Huernia and Orbea , whose flowers give off a carrion odor , the wax flowers ( Hoya ), the swallowweed ( Vincetoxicum hirundinaria ) and the silk plants ( Asclepias ).

Vegetative characteristics

They are usually perennial herbaceous plants or woody plants: shrubs , lianas or rarely trees . Part of the taxa are stem succulent plants. Some species are climbing plants. The plants often contain a whitish or, more rarely, clear milky sap .

The mostly opposite leaves are well developed or greatly reduced. The leaves usually have a smooth leaf edge. Stipules may be present or absent.

Generative characteristics

The flowers are solitary or in zymose , rarely racemose inflorescences .

The hermaphrodite flowers are mostly radial symmetry and fünfzählig double perianth (perianth). The five sepals are only fused at their base. The five petals are fused. A secondary crown is often formed from the petals or the stamens ( ligula ). There is only one circle with five stamens , the stamens being short or missing. The stamens and carpels are fused together to form a so-called " gynostegium ". The pollen is usually combined into one unit, the " pollinium ". The “pollinium” is connected to the “clamp body” via two so-called “translators”. Each flower contains two upper carpels .

Usually two follicles develop per flower , rarely only one. The follicles contain many seeds. The seeds usually have silky hairs (coma), hence the name.

ecology

The gynostegium specializes in insect pollination ( entomophilia ).

The former family Asclepiadaceae was set up in 1797 by Moritz Balthasar Borkhausen in Botanical Dictionary , Volume 1, p. 31. For practical reasons, Robert Brown divided the "Asclepiads" Jussieu's (1789) Apocineae in 1810, and with the scope of his own family Asclepiadaceae. The name of the Asclepiadaceae family - still known as "Asclepiadeae" - goes back to Gilbert Thomas Burnett in 1835. Type genus is Asclepias L. It has to molecular biological findings to the rank of subfamily Asclepiadoideae within the family of the Apocynaceae (Endress & Bruyn 2000). Other synonyms for Asclepiadaceae R.Br. ex Burnett are: Cynanchoideae Luerss. , Marsdenioideae Luerss.

The species of the subfamily Asclepiadoideae are widespread in the tropical and subtropical regions of the world, especially in Africa and southern South America. In northern and southeast Asia there are few species, but many small genera. In Central Europe only is milkweed ( Vincetoxicum hirundinaria ) native, originally from North America Milkweed ( Asclepias syriaca ) is in Central Europe wild and partly naturalized before.

The subfamily Asclepiadoideae includes 164 to 172 genera .

The subfamily Asclepiadoideae was created by Endress et al. 2007 divided into four tribes with a total of twelve sub - tribus . It has been used since Endress et al. 2014 divided into five tribes with a total of 15 sub-tribuses:
