Arachis is a genus of about 70 species of annual and perennial flowering plants in the family (Fabaceae), native to South America, and was recently assigned to the informal monophyletic Pterocarpus clade of the Dalbergieae. [2] [3] At least one species, the peanut (Arachis hypogaea), is a major food crop species of global importance; some of the other species are cultivated for food to a small extent in South America. Other species such as A. pintoi are cultivated worldwide as forage and soil conditioner plants, with the leaves providing high-protein feed for grazing livestock and a nitrogen source in agroforestry and permaculture systems.

Contents

Arachis species, including the peanut, are used as food plants by some Lepidoptera species, including the flame shoulder, nutmeg, and turnip moth. [4]

<span class="mw-page-title-main">Peanut</span> Legume cultivated as a grain and oil crop

The peanut, also known as the groundnut, goober (US), pindar (US) or monkey nut (UK), is a legume crop grown mainly for its edible seeds. It is widely grown in the tropics and subtropics, important to both small and large commercial producers. It is classified as both a grain legume and, due to its high oil content, an oil crop. World annual production of shelled peanuts was 44 million tonnes in 2016, led by China with 38% of the world total. Atypically among legume crop plants, peanut pods develop underground (geocarpy) rather than above ground. With this characteristic in mind, the botanist Carl Linnaeus gave peanuts the specific epithet hypogaea, which means "under the earth".

<i>Lupinus</i> Genus of leguminous plants

Lupinus, commonly known as lupin, lupine, or regionally bluebonnet etc., is a genus of plants in the legume family Fabaceae. The genus includes over 199 species, with centers of diversity in North and South America. Smaller centers occur in North Africa and the Mediterranean. They are widely cultivated, both as a food source and as ornamental plants, but are invasive to some areas.

<i>Dalbergia</i> Genus of legumes

Dalbergia is a large genus of small to medium-size trees, shrubs and lianas in the pea family, Fabaceae, subfamily Faboideae. It was recently assigned to the informal monophyletic Dalbergia clade : the Dalbergieae. The genus has a wide distribution, native to the tropical regions of Central and South America, Africa, Madagascar and southern Asia.

<i>Vigna</i> Genus of plants

Vigna is a genus of plants in the legume family, Fabaceae, with a pantropical distribution. It includes some well-known cultivated species, including many types of beans. Some are former members of the genus Phaseolus. According to Hortus Third, Vigna differs from Phaseolus in biochemistry and pollen structure, and in details of the style and stipules.

<i>Indigofera</i> Genus of plants

Indigofera is a large genus of over 750 species of flowering plants belonging to the pea family Fabaceae. They are widely distributed throughout the tropical and subtropical regions of the world.

Arachis diogoi is a perennial herb found in Africa, Indian Ocean and South America. This plant is cited as gene sources for research in plant biology of peanut.

Arachis villosulicarpa is a perennial peanut species, which is cultivated by indigenous people in Mato Grosso, a state of Brazil. Its wild progenitor is thought to be Arachis pietrarellii. Although it is related to the common peanut, Arachis hypogaea, it was separately domesticated: A. villosulicarpa is diploid, whereas A. hypogaea is tetraploid.

<i>Centrosema</i> Genus of legumes

Centrosema, the butterfly peas, is a genus of American vines in the legume family (Fabaceae). It includes 44 species, which range through the tropical and warm-temperate Americas from the southern United States to northern Argentina. Species include:

<i>Chamaecrista</i> Genus of legumes

Chamaecrista is a genus of flowering plants in the pea family, Fabaceae, subfamily Caesalpinioideae. Members of the genus are commonly known as sensitive pea. Several species are capable of rapid plant movement. Unlike the related genera Cassia and Senna, members of Chamaecrista form root nodules.

<i>Machaerium</i> (plant) Genus of legumes

Machaerium is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. It contains the following species:

<i>Aeschynomene</i> Genus of legumes

Aeschynomene is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. They are known commonly as jointvetches. They range across tropical and subtropical regions of the Americas, sub-Saharan Africa, south, southeast, and east Asia, and Australia. These legumes are most common in warm regions and many species are aquatic.

<i>Vachellia</i> Genus of legumes

Vachellia is a genus of flowering plants in the legume family, Fabaceae, commonly known as thorn trees or acacias. It belongs to the subfamily Mimosoideae. Its species were considered members of genus Acacia until 2009. Vachellia can be distinguished from other acacias by its capitate inflorescences and spinescent stipules. Before discovery of the New World, Europeans in the Mediterranean region were familiar with several species of Vachellia, which they knew as sources of medicine, and had names for them that they inherited from the Greeks and Romans.

<i>Adesmia</i> (plant) Genus of legumes

Adesmia is a genus of flowering plants in the legume family, Fabaceae. It was recently assigned to the informal monophyletic Adesmia clade within the Dalbergieae.

<i>Hippocratea</i> Genus of Celastraceae plants

Hippocratea is a genus of flowering plants in the family Celastraceae, usually lianas, native to tropical and subtropical North America, South America and Africa.
