The small flower heads consist of many twin-petalled florets. The leaves in three, trefoil.

The fine leaf teeth become coarser towards the end of the leaf which ends in a minute point.

The trefoil leaves have minute teeth and a delineating minutely pointed tooth at the end in a slight depression.

From the spent flower on the left where the hairy sepals can be seen a mass of coiled pods will form.

The hairy and ridged pods extrude themselves from the sepal tube, curl around and expand.

When ripe the pods become blackened. There is a ribbed netted pattern on the surface.

The trefoil leaves showing minute teeth and stipule at the tip. Only the central leaflet is stalked. The longer stems are more often square.

The leaf triplets. The centre one has a longer petiole (stem). All have a pointed tooth but which is NOT a mucronate tip (as some botanical books say). It is not fine enough to be a mucronate tip, what it actually is is a tooth in a slight depression at the end of the leaf. Leaves variably hairy.


Easily confused with : other Hop Trefoils. The distinguishing feature from those is the naked and black pods, plus the isolated tooth at the tip of the leaves which nestles in a slight depression. The tip is NOT a mucronate!
