Black Medick

Black Medick - Medicago lupulina

Description

Low, often prostrate, hairy plant. Leaves are trifoliate and widest above the middle, with a nerve protruding at the broad end of each leaflet in the centre. Flowers yellow, 2 to 3 mm, many to a raceme. Pods coiled, sickle or kidney shaped, 1.5 to 3 mm, black when ripe.

Similar Species

Hop-trefoils - Trifolium dubium, campestre and micranthum

Identification difficulty
ID checklist (your specimen should have all of these features)

If there aren't any fruits, distinguished from the Hop-trefoils by the apiculate leaves - i.e. with a short fine 'needle' at the apex of the leaf. The leaves are also much hairier than the leaves of Hop-trefoils.
