Mentha arvensis herbarium specimen from Braunton, VC4 North Devon in 1925 by Francis Morland Day.
fruits/flowers:mature flowers
notes:I do not think I have seen this before. I think it is arvensis. The dense whorls and the triangular calyx both point to this; though these are long, as are the calyces. It may be one of the forms of verticillata coming near the arvensis parent. I had a similar form from S. Wales which Fraser put under paludosa on a/c of the long calyx teeth. A.L.S.

Inferred details are marked.
