Very variable in leaflet shape, and sometimes divided, on this basis, into 2 species or subspecies, but there is little correlation between leaflet shape and other characters.
Closely allied to L. odoratus L. (the sweet-pea), which is a hairy annual, with 1-3 flowers in the raceme, a shorter hairy pod and smooth globular seeds; a native of southern Italy and Sicily.
