Tetrastigma is a genus of plants in the grape family, Vitaceae. The plants are lianas that climb with tendrils and have palmately compound leaves. Plants are dioecious, with separate male and female plants; female flowers are characterized by their four-lobed stigmas. [2] The species are found in subtropical and tropical regions of Asia, Malaysia, and Australia, where they grow in primary rainforest, gallery forest and monsoon forest and moister woodland. Species of this genus are notable as being the sole hosts of parasitic plants in the family Rafflesiaceae, one of which, Rafflesia arnoldii , produces the largest single flower in the world. [3] Tetrastigma is the donor species for horizontal gene transfer to Sapria and Rafflesia due to multiple gene theft events. [4]
Within the Vitaceae, Tetrastigma has long been considered closely related to Cayratia and Cyphostemma [5] and is now placed in the tribe Cayratieae.
A fossil seed fragment from the early Miocene of Tetrastigma sp., has been found in the Czech part of the Zittau Basin. [6] Tetrastigma macrofossils have been recovered from the late Zanclean stage of Pliocene sites in Pocapaglia, Italy. [7]
Tetrastigma is derived from Greek and means 'four stigmas', in reference to its four-lobed stigma. [8]

The Vitaceae are a family of flowering plants, with 14 genera and around 910 known species, including common plants such as grapevines and Virginia creeper. The family name is derived from the genus Vitis.
Argyreia is a genus of plants in the family Convolvulaceae.
Calophyllum is a genus of tropical flowering plants in the family Calophyllaceae. They are mainly distributed in Asia, with some species in Africa, the Americas, Australasia, and the Pacific Islands.
Cissus is a genus of approximately 350 species of lianas in the grape family (Vitaceae). They have a cosmopolitan distribution, though the majority are to be found in the tropics.
Pterospermum is a genus of flowering plants in the mallow family Malvaceae. Its species are tropical trees that range from southern China across tropical Asia.
Leea is a genus of plants in the family Vitaceae, subfamily Leeoideae, that are native to parts of central Africa, tropical Asia, Australia and Melanesia. It was previously placed in its own family, Leeaceae, based on morphological differences between it and other Vitaceae genera. These differences include ovule number per locule, carpel number, and the absence or presence of a staminoidal tube and floral disc. Pollen structure has also been examined for taxonomic demarcation, though studies have concluded that the pollen of Leeaceae and Vitaceae suggests the families should remain separate while other studies conclude that Leea should be included in Vitaceae.
The genus Cayratia consists of species of vine plants, typical of the tribe Cayratieae. Some of them are useful, and they are found in tropical and subtropical areas of Asia, Africa, Australia, and islands of the Pacific Ocean.
Archidendron is a genus of flowering plants in the pea family, Fabaceae. It includes 98 species which range from India through Indochina, southern China, Taiwan, Malesia, and Papuasia to Queensland and New South Wales.
Goniothalamus is one of the largest palaeotropical genera of plant in family Annonaceae.
Polyalthia is a genus of flowering plants in the family Annonaceae. There are approximately 90 species distributed from Africa to Asia and the Pacific.
Ampelocissus is a genus of Vitaceae having 90 or more species found variously in tropical Africa, Asia, Central America, and Oceania. The type species, A. latifolia, was originally treated under its basionym, Vitis latifolia, and was collected from the Indian subcontinent.
Mussaenda is a genus of flowering plants in the family Rubiaceae. They are native to the African and Asian tropics and subtropics. Several species are cultivated as ornamental plants.
Globba is a genus of plants in the ginger family. It contains about 100 species, native to China, the Indian Subcontinent, Southeast Asia, New Guinea, the Bismarck Archipelago and Queensland.
Pterisanthes is a vine plant genus in the subfamily Vitoideae. Its native range is Indochina to W. Malesia including the Philippines. The relationship between Pterisanthes and another genus "Nothocissus" with Ampelocissus has been debated, with the latter now subsumed within Ampelocissus, but with Pterisanthes retained.
The Cayratieae is one of five tribes of vine plants that are now recognised in this subfamily Vitoideae. It contains genera restored or newly erected from species in the previously configured genus Cayratia, which was found not be monophyletic:.
