 Bobart, as I have already mentioned, once took the variegated genUlis 

 of the gardens to be the Mint of Vernon. I know not that this un- 

 certainty can ever be removed, except fome old herbarium fliould 

 unexpedledly afford an original fpecimen. 



£ is a very remarkable plant, for which I am obliged to Mr. Sole, 

 the only perfon I believe who has found it ; and I have been much 

 inclined to make it, as he does, a diflin6l fpecies. Its leaves are very 

 broad and almoil: heart-lTiaped, marked with ftrong parallel veins 

 which render them rugofe. The ftamina are fhorter than the co- 

 rolla. In every other particular, even in fmell, it agrees perfedlly 

 with M. arvenfis, efpecially in the calyx and flower-ftalk ; and I think 

 it muft be confidered as a variety, for I have abundant proofs that 

 the fhape of the leaves is more liable to vary in this fpecies than 

 even mofl: others.
