Landolphia is a genus of flowering plants in the family Apocynaceae first described as a genus in 1806. They take the form of vines that scramble over host trees. Landolphia is native to tropical Africa. [1]
There are about fifty species of Landolphia in continental Africa and about fourteen more species in Madagascar. They are typically found in forest habitats in tropical West and Central Africa, scrambling over trees, but a few species are large shrubs. They have simple, glossy green leaves in opposite pairs, jasmine-like flowers with tubes and parts in fives, and hard-shelled, fleshy fruits with several seeds embedded in the pulp. After fruiting, the flower stem develops into a twisting tendril which branches near its tip. [2] [3]
Members of this genus exude latex when the bark is damaged. The vines have traditionally been used to supply rubber but that function has increasingly been taken over by the rubber tree, Hevea brasiliensis which can be conveniently grown in plantations. The latex from these vines is still used to a limited extent for rubber production. Many species have large edible fruits which are sweet and juicy and rich in beta-carotene. However, commercialisation of the crop is difficult because of the nature of the vines, their need for suitable supports and the lack of knowledge of suitable cultivation techniques. [2]
Tabernaemontana is a genus of flowering plants in the family Apocynaceae. It has a pan-tropical distribution, found in Asia, Africa, Australia, North America, South America, and a wide assortment of oceanic islands. These plants are evergreen shrubs and small trees growing to 1–15 m tall. The leaves are opposite, 3–25 cm long, with milky sap; hence it is one of the diverse plant genera commonly called "milkwood". The flowers are fragrant, white, 1–5 cm in diameter.
Strophanthus is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1802. It is native primarily to tropical Africa, extending to South Africa, with a few species in Asia from southern India to New Guinea and southern China. The genus name is a compound of the Greek words στροφος (strophos) "twisted" and ανθοσ (anthos) "flower", in reference to the corolla lobes which, in some species - notably S. petersianus - resemble long twisted ribbons or threads and can reach a length of 30–35 cm. This trait, in addition to colouring involving combinations of bright pinks, purples and oranges, combine to make the flowers among the most ornamental in the plant kingdom.
Pycnocoma is a genus of plant of the family Euphorbiaceae first described as a genus in 1849. It is native to tropical Africa and Madagascar.
Angraecopsis is a genus of plants in the family Orchidaceae. It was first described by Fritz Kraenzlin in 1900 and given its name on account with the genus' similarity to Angraecum species. Angraecopsis are native to Africa, Madagascar, Réunion, Mauritius and the Comoros. The growth habit is rather small and the leaves emerge from a woody stem.
Hunteria is a genus of plants in the family Apocynaceae first described as a genus in 1824. It is native to Africa and to South and Southeast Asia.
Pleioceras is a genus of plants in the family Apocynaceae, first described as a genus in 1888. It is native to tropical Africa.
Eremospatha is a genus of climbing flowering plants in the palm family found in tropical Africa. These rattans are uncommon in cultivation and poorly understood by taxonomists. Closely related to Laccosperma, they are differentiated by the near complete absence of bracts and bracteoles. The name is from Greek meaning "without a spathe".
Hyparrhenia is a genus of grasses. Many species are known commonly as thatching grass.
Anchomanes is a genus of flowering plants in the family Araceae. The genus is native to tropical Africa.
Cercestis is a genus of flowering plants in the family Araceae. The species in this genus are all climbers and are native to Africa. At intervals along the stem they produce long leafless shoots called flagella. Many of the species in Cersestis show signs of fenestration.
Culcasia is a genus of flowering plants in the family Araceae, native to tropical Africa. Most of its species are climbers and resemble Cercestis, except that they do not produce flagella.
Craterispermum is a genus of flowering plants in the family Rubiaceae. It contains 16 species that occur in tropical Africa and Seychelles. It is the only genus in the tribe Craterispermeae, of which the divergence time is estimated at 34.8 million years ago.
Voacanga is a genus of plants in the family Apocynaceae found in Africa, Southeast Asia, New Guinea, and Australia. As of August 2013 the World Checklist of Selected Plant Families recognises 13 species:
Englerophytum is a group of trees in the family Sapotaceae described as a genus in 1914.
Mesanthemum is a genus of flowering plants in the family Eriocaulaceae, first described in 1856. It is native to tropical Africa and Madagascar.
Orthopichonia is a genus of plants in the family Apocynaceae, first described as a genus in 1953. It was initially given the name Orthandra, but this turned out to be an illegitimate homonym. Orthopichonia is native to Africa.
Vahadenia is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1902. It is native to tropical Africa.
Landolphia owariensis is a species of liana from the family Apocynaceae found in tropical Africa. Latex can be extracted from this plant for the manufacture of natural rubber. Other names for this vine are eta, the white rubber vine and the Congo rubber plant. Congo rubber was a commercial rubber exported from the Congo Free State starting in 1890, most notable for its forced harvesting under conditions of great human suffering, in the Congo Free State, detailed in the 1904 Casement Report. From 1885 to 1908, millions died as a result of murder, deprivation, and disease, with population falling by millions in this period; some writers estimate this loss to be as high as 10 million people.
