The vetch with two seeds is an annual plant with a mainly western Mediterranean distribution, present in almost all the regions of Central and Southern Italy, in Liguria and in Emilia-Romagna. It grows in uncultivated meadows and in dry grasslands, mainly on siliceous substrates, from sea level to the lower montane zone. The species sporadically appears in the outer belt of the temporary ponds of Sardinia, in contact with dry grasslands or pastures. The genus name derives from the Latin 'viere' or 'vincire' (to tie), referring to the presence of tendrils with which many species cling to a support; the species name refers to the legumes, that usually include only two seeds. Flowering period: April to May.

Italian name(s): Veccia con 2 semi (Italia), Veccia disperma (Italia).
