Comments:

Further work could be done on taking close-up pictures showing the vegetative differences between this species and Medicago lupulina.

The Plant Crib gives the details as follows:

MEDICAGO LUPULINA / TRIFOLIUM DUBIUM

Vegetatively, these two species can be distinguished as follows:

Medicago lupulina L.: Usually densely hairy, with leaflets which are toothed on the margins and entire to emarginate at the apex but with a small distinct point in the middle; stipule often with small, obtuse teeth.

Trifolium dubium Sibth.: Sparsely hairy to glabrous and has leaflets which are toothed on the margins and entire to emarginate at the apex; stipule entire.

In our discussions with Bart over the Zimbabwe material, some of the younger leaves of T. dubium appeared to have fine bristles at the apex - does this happen?

And can we photograph the stipule character?
