Occasional by roadsides and on cultivated ground.

Flower whorls c 10-18 mm diameter.

ID: Told as a mint by scent.  Flowers in whorls at base of leaves, stem terminates in leaves not flowers.  Told from M x verticillata by the calyx-tube being about as broad as long, and the calyx-teeth also about as broad as long.  In M x verticillata both these are much longer than broad.

Other features: Leaves stalked, 2-3 x as long as broad.  Flower-stalks may be hairless or hairy (always hairy in M x verticillata).  Stamens often protruding from the flower-tube (very rarely protruding in M x verticillata).
