Leaves subsessile, or the lowei- ones shortly stalked, ovate or 

 triangular-ovate, subacute, laciniate and crisped at the margins, finely 

 pubescent above, more thickly so or woolly beneath. Spikes cylin- 

 drical-oblong, rather dense, thick. Bracts lanceolate ; bracteoles 

 linear-subulate, as long as the flowers. Pedicels glabrous. Calyx 

 spai-ingly bristly-hairy, obconical-campanulate ; teeth triangular- 

 subulate, nearly as long as the tube. Corolla twice as long as the 

 calyx, very slightly hairy without, glabrous within. 



On the banks of the Woolcr Water, near Haugh Head, and on the 

 banlcs of a rivulet leading from the same water above Longley Ford, 

 Northumberland. 



[England.] Perennial. Autumn, 



There can be no doubt that this mmt is a monstrosity, but it seems 

 hopeless to discover to which species it ought to be referred. Such 

 writers as Wu-tgen and Baker, who have more especially studied 

 the mints, incline to the supposition that it is a form of jI. pi^jerita, 

 from which, however, it difters remarkably m the suppression of the 

 petioles of the leaves, which latter are also much more hairy: the 

 calyx also differs in being more hairy, the tube more narrowed towards 

 the base, and the teeth much longer in proportion. It is more hairy 

 than M. citrata, to which it is referred by Boreau, and less so than 

 }.I. hirsuta, and from both these latter forms it diifers in the subsessile 

 leaves and spiked, not ca])itate, inflorescence. From the crisped variety 

 of M. viridis it difters in the leaves being more distinctly stalked, the 

 spikes much shorter and blunter, and the corolla having a lew hairs 

 on the outside. From M. pubcscens it is separated by the subsessile 

 leaves, longer calyx-teeth, and more fragrant scent.
