Hop Trefoil - Trifolium campestre

Similar Species

Trifolium dubium, Trifolium micranthum, Medicago lupulina

Identification difficulty
ID guidance

Broad, flat standards that fold downwards over the pods, looking a bit like a hop-flower.  Larger and paler than Lesser Hop-trefoil, and turns brownish with age.  Both trefoils are similar to Black Medick in flower, but Black Medick leaves are much more hairy and have an apiculate point (i.e a short fine 'needle' from the end of the leaflet)
