Fabaceae

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, are a large and agriculturally important <a href="/facts/Family_(biology)/qTrn6E8E">family</a> of <a href="/facts/Flowering_plant/E5eGYIvY">flowering plants</a>. It includes <a href="/facts/Tree/HVVn3srN">trees</a>, <a href="/facts/Shrub/X1gKVxL5">shrubs</a>, and <a href="/facts/Perennial/MQ3NvAUW">perennial</a> or <a href="/facts/Annual_plant/SkPv72DA">annual</a> <a href="/facts/Herbaceous_plant/u6myDhE2">herbaceous plants</a>, which are easily recognized by their fruit (<a href="/facts/Legume/x6s6gVHY">legume</a>) and their compound, <a href="/facts/Stipule/dpF27NFo">stipulate</a> leaves. The family is widely distributed, and is the third-largest <a href="/facts/Land_plant/8pzYKGvv">land plant</a> family in number of species, behind only the <a href="/facts/Orchidaceae/UKmu0DhW">Orchidaceae</a> and <a href="/facts/Asteraceae/bouc6v8C">Asteraceae</a>, with about 765 genera and nearly 20,000 known species.
The five largest genera of the family are <a href="/facts/Astragalus_(plant)/sxf73Fy6">Astragalus</a> (over 3,000 species), <a href="/facts/Acacia/Lw9T7Hy6">Acacia</a> (over 1,000 species), <a href="/facts/Indigofera/z5V5GDsj">Indigofera</a> (around 700 species), <a href="/facts/Crotalaria/brjeLovG">Crotalaria</a> (around 700 species), and <a href="/facts/Mimosa/l56L3csD">Mimosa</a> (around 400 species), which constitute about a quarter of all legume species. The c. 19,000 known legume species amount to about 7% of flowering plant species. Fabaceae is the most common family found in tropical rainforests and dry forests of the Americas and Africa.
Recent molecular and morphological evidence supports the fact that the Fabaceae is a single <a href="/facts/Monophyletic/pD8Yrrn6">monophyletic</a> family. This conclusion has been supported not only by the degree of interrelation shown by different groups within the family compared with that found among the Leguminosae and their closest relations, but also by all the recent <a href="/facts/Phylogenetic/bw4rsovt">phylogenetic</a> studies based on <a href="/facts/DNA/nB89Iauz">DNA</a> sequences. These studies confirm that the Fabaceae are a monophyletic group that is closely related to the families <a href="/facts/Polygalaceae/aY3wldjM">Polygalaceae</a>, <a href="/facts/Surianaceae/Uydmkv4f">Surianaceae</a> and <a href="/facts/Quillajaceae/prSKofHS">Quillajaceae</a> and that they belong to the order <a href="/facts/Fabales/H0aMr1uL">Fabales</a>.
Along with the <a href="/facts/Cereal/ao2WcFdM">cereals</a>, some fruits and tropical roots, a number of Leguminosae have been a staple human food for millennia and their use is closely related to <a href="/facts/Human_evolution/DNzlDyKe">human evolution</a>.
The family Fabaceae includes a number of plants that are common in agriculture including Glycine max (<a href="/facts/Soybean/reNwxvo2">soybean</a>), <a href="/facts/Phaseolus/3JLzd8wX">Phaseolus</a> (beans), Pisum sativum (<a href="/facts/Pea/hlndxpId">pea</a>), Cicer arietinum (<a href="/facts/Chickpea/gRKRpqWp">chickpeas</a>), Vicia faba (<a href="/facts/Vicia_faba/KPxa7j4I">broad bean</a>), Medicago sativa (<a href="/facts/Alfalfa/Yesc424s">alfalfa</a>), Arachis hypogaea (<a href="/facts/Peanut/dMd0XWsu">peanut</a>), <a href="/facts/Ceratonia_siliqua/ywD6ybUg">Ceratonia siliqua</a> (carob), Trigonella foenum-graecum (<a href="/facts/Fenugreek/1BKUXEwj">fenugreek</a>), and Glycyrrhiza glabra (<a href="/facts/Liquorice/AopJFtbo">liquorice</a>). A number of species are also weedy <a href="/facts/Pest_(organism)/mXGHJ8s7">pests</a> in different parts of the world, including <a href="/facts/Cytisus_scoparius/T7VbD4nM">Cytisus scoparius</a> (broom), <a href="/facts/Robinia_pseudoacacia/IYlECUoF">Robinia pseudoacacia</a> (black locust), <a href="/facts/Ulex_europaeus/vllAoI1j">Ulex europaeus</a> (gorse), <a href="/facts/Pueraria_montana/M3SH5cBD">Pueraria montana</a> (kudzu), and a number of <a href="/facts/Lupinus/Yln4bpqe">Lupinus</a> species.
