Vegetative characteristics

Vincetoxicum species grow as little branched rarely shrubs, mostly subshrubs or perennial herbaceous plants, erect or climbing grow independently and (rarely to 200) reach stature heights of 40 to 100 cm. Many species form rhizomes as outlasting. The plants contain a colorless milky sap. Even with the woody species most of the aboveground plant parts is usually for just one year and hairless hairy until fluffy.

The mostly opposite arranged leaves are stalked at least briefly. The simple, herbaceous to papery leaf blades are ovate to somewhat heart-shaped, 5-10 cm long and 2-8 cm wide. The leaf margins are ciliate.

Inflorescences and flowers

The springing in the internodes, sometimes paired, total branched inflorescences are usually shorter than the related leaves and composed of differently constructed part inflorescences; they comprise 5 to 20 flowers. Blütenstandsschäfte and flower stalks are about the same length and both hairy either smooth or downy.

The usually relatively small, radial symmetry, hermaphrodite, five petals contain nectar. The five monochrome yellowish cream-colored to purple -brown sepals have a length of 2.5 to 6 mm and have grown to more than half of their length. The calyx tube is longer than the corolla tube. The Corolla lobe are spread to bent back. The deformed from staminal and interstaminalen parts, fleshy corona is at most equal to the short -stalked up sitting " Gynostegium ". The colors of the corona range from white to ivory to yellow and pink to purple. The staminal are longer and thicker than the interstaminalen parts. The hanging pollinia are oval to spherical or oblong. The cream-colored or green scar head is flat to be highlighted.

Fruit and seeds

Most produced only one follicle per flower, but they are upright, horizontal hanging up often paired together. The hairless, light brown follicles have a length of 6 to 9 cm and a diameter of 5 to 8 mm, are spindle - shaped and pencil, wingless and longitudinally grooved with a schnabeligen tip, with thin pericarp. The light to medium brown seeds are ovoid, 4-8 mm long, 2.5 to 3.5 mm wide and have at the edges 0.2 to 0.3 mm wing with a smooth edge and Flight hair. As diaspore seeds and dissemination are carried by the wind.

Ingredients and chromosome numbers

They contain alkaloids, Seco and Disecopregnane. The base chromosome number is n = 11

Systematics and distribution

The genus Vincetoxicum comes only in the Old World before in many parts of Eurasia. They thrive depending on the type of sunny forest edges, in xerophytic vegetation, dry areas of Central Asia, rocky slopes, ravines or steppes.

The genus name Vincetoxicum was first published in 1776 by Nathanael Matthew Wolf in Genera Plantarum, p 130. The publication of Thomas Walter in Flora Caroliniana, secundum ..., 13, pp. 104 was only 1788. Vincetoxicum type species is hirundinaria Medik ..

The genus belongs to the subtribe Vincetoxicum Tylophorinae ( K.Schum. ) Songs from the tribe Asclepiadeae in the subfamily Asclepiadoideae within the family Apocynaceae.

  • Vincetoxicum inamoenum Maxim. It is widely used in China, Japan, Korea and Russia.
  • Vincetoxicum mongolicum Maxim. Thrives in the mountains and sand areas at altitudes 0-3000 meters in the Chinese provinces of Gansu, Hebei, Nei Mongol, Ningxia, Qinghai, Shaanxi, Shanxi and Sichuan.
  • Vincetoxicum pycnostelma Kitag.
  • Vincetoxicum rossicum ( Kleopow ) Barbar.
  • Vincetoxicum sakesarense Ali & S. Khatoon: This endemic species is known only from its type location in the Sakesar hills in the Pakistani district Sargodha.
  • Vincetoxicum sibiricum (L.) Decne.
  • Vincetoxicum stauntonii ( Decne. ) CYWu & DZLi: It is native to the low to medium altitudes in China.
  • Vincetoxicum stocksii Ali & Khatoon: It is endemic to Baluchistan.
  • Vincetoxicum thesioides Freyn: It is widely used in high altitudes 0-3000 meters in China, Kazakhstan, Korea, Mongolia and Russia.

The medical effects of some types were investigated. Note: most parts of plants of many species are poisonous.
