The genus '''''Lotus''''' ('''Bird's-foot Trefoil''', '''Trefoil''' or '''Deervetch''') contains approximately 150 species distributed world-wide. ''Lotus'' is a genus of [[legume]] and its members are adapted to a wide range of habitats, from coastal environments to high altitudes. Most species have [[leaf|leaves]] with three leaflets, but also two large [[stipule]]s at the base roughly equal in size to the leaflets, thus appearing to have ''five'' leaflets; some species have pinnate leaves with up to 15 leaflets. The [[flower]]s are in clusters of 3-10 together at the apex of a stem with some basal leafy [[bract]]s, [[pea]]-flower shaped, vivid yellow or orange, occasionally red.
''Lotus'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species - see [[list of Lepidoptera which feed on birds-foot trefoils]].

[[Image:Lotuscorniculatus.jpg|thumb|250px|[[Pasture]] with ''Lotus corniculatus'']]
Several species are culvivated for [[forage]], including ''L. corniculatus'', ''L. glaber'' and ''L. uliginosus''. Scentific research for crop improvement and understanding the general biology of the genus is focused on ''L. japonicus'' which is currently the subject of a full genome sequencing project, and is considered a [[model organism]].
They can produce toxic [[cyanide|cyanogenic glycoside]]s which can be potentially toxic to [[livestock]], but also produce [[tannin]]s, which are a beneficial anti-[[bloat]]ing compound.
Some species, such as ''L. berthelotii'' from the [[Canary Islands]], are grown as ornamental plants. ''L. corniculatus'' is an [[invasive species]] in some regions of [[North America]] and [[Australia]].
