Vicia tenuifolia, the fine-leaved vetch, cow vetch,[3] fodder vetch[4] or bramble vetch,[1] is a herbaceous perennial plant species in the family Fabaceae.[5] This species is widespread in Europe and some parts of both Asia and Africa. In some other areas it occurs as an introduced species.[1] In a few countries this edible vetch is used as food for both humans and farm animals.[5]
Vicia tenuifolia was described by German botanist Albrecht Wilhelm Roth in his work Tentamen florae germanicae in 1788.[2] Some taxonomists treat this species as a subspecies of Vicia cracca, while most recognize it as its own species.[2][6]
There are a few recognized subspecies:[2]
This herbaceous and perennial legume can reach from 30 to 150 centimetres of height. It is usually an upright-growing and spread out vetch with rough stem that is either hairless either hirsute.[5] As with many other pea family species, Vicia tenuifolia is a nitrogen-fixing plant.[3]
Its alternately arranged leaves are pinnately compound and most of the times consist of 10–18 pairs of narrowly linear to oblong leaflets.[5][7] Pinna can be both hirsute or hairless and usually measure from 2 to 6 millimetres. Vicia tenuifolia has so called paripinnate leaves, that end with a split tendril. Stipules are present; they are narrowly linear, with entire leaf margin and end with a sharpened point.[5]
The species is an entomophilous plant[3] and flowers between June and August.[8] Vicia tenuifolia has typical bilaterally symmetrical papilionaceous flowers, that consists of a banner, keel and wing, with the flower's petals being red, pink or blueish purple. The biggest petal – the so-called banner – is brighter than other petals, with its limb being as long as its claw.[5] From 15 to 30 small flowers are arranged into an raceme inflorescence,[7] that has long leafstalk (the latter is usually twice as long as the inflorescence). The flower's sepals are fused together into a few millimetres long calyx tube that ends with 5 short calyx tooth. Each flower has 10 anthers; the latter are fused together till the last third of anther's length.[5]
This species' dried fruit is a brownish and hairless legume that can measure from 3 to 5 centimetres.[5]
Vicia grandiflora can be confused with the similar vetch species Vicia dalmatica, Vicia cracca, Vicia incana and Vicia villosa.[5]
This vetch species is widely distributed across Europe (especially the Euro-Mediterranean region,[9] south and central Europe[10]) and occurs also in some parts of Asia (usually those that are either temperate either tropical,[1] mostly southwestern and central Asia[10]), as well as in northern Africa.[1] In north-western Europe it is not a native species.[6] Vicia tenuifolia was once introduced to Hawaii.[1] In some areas it is treated as an invasive species.[11]
Vicia tenuifolia usually grows in a variety of habitats, which can include both natural and urban areas.[5] This vetch is mostly an inhabitant of lowlands,[6] where it can be found in dry meadows and forest edges, as well as on grassy banks, verges or waste ground, especially near railways,[6] where it is a ruderal species.[5] V. tenuifolia rarely occurs in uplands, with its maximum elevation being around 2,900 metres.[1]
This species is listed as least concern (LC) species on the IUCN Red list, with its population being rated as stable.[1]
