All species are perennial plants. There are either evergreen or deciduous climbing shrubs and vines, usually with winding tendrils; or there are shrubs or succulents.

The leaves are arranged opposite one another and double-spaced. The leaf blades are simple, palmately lobed or compound. The leaves are usually hairy or tomentose spinnwebig on the bottom, these guard hairs are made of dead cells. In the veins of one or multicellular trichomes are often living, yet. The leaf edges may be serrated. They have fast transient stipules.

Inflorescences and flowers

The flowers are never alone, but always in, often complicated branched inflorescences: the basic structure of panicles or cymes ( botanical point of view, it is therefore not grapes! ) Incurred in the axes of the leaves. Among the flower stems are always small bracts.

The hermaphrodite or unisexual flowers are radial symmetry and are four or fünfzählig (rarely to siebenzählig ). The species can be a ( monoecious ) or dioecious ( dioecious ). It's just a circle with four or five ( or seven ) stamens present. Most of two carpels to form the Upper constant ovary. It is a mostly - cup to cup-shaped, discus available, which is a disk of nectar-secreting glands.

System

The Vitaceae family was erected in 1789 by Antoine- Laurent de Jussieu in Genera Plantarum, p 267 under the name " Vites ". Type genus Vitis L. is. Synonyms for Vitaceae Juss. are: Ampelopsidaceae Kostel, Cissaceae Drejer, Leeaceae Dumort. . nom. cons. , Pterisanthaceae J.Agardh.

The Grape Family ( Vitaceae ) family is divided into two subfamilies with 14 to 16 genera and 850-900 species:

• Subfamily Vitoideae Eaton: The basic chromosome number is x = 10-16, 19, 20 It contains 14 to 15 genera: Acareosperma Gagnep. There is only one way: Acareosperma spireanum Gagnep. It is native to Laos.

• Clematicissus angustissima ( F.Muell. ) Planch. It occurs only in the western Western Australia.

• Nothocissus spicifera ( Griff. ) Latiff: It occurs on the Thai peninsula, Malay Peninsula, Sumatra and Borneo.

• Pterocissus mirabilis Urb. & Ekman: It occurs only on Hispaniola.

• Subfamily Leeoideae Burmeister: Even as his own family Leeaceae Dumort. out: The basic chromosome number is x = (10 - ) 12 It contains only one genus: Leea L.: The approximately 34 species in tropical and subtropical Asia widespread, date back to the Himalayan region and Australia, only a few species there are in Africa and only one in Madagascar.
