260 55. LAMIACE-E. 



Native. Agrestal, Sylvestral. We have certainly tw( 

 forms of this plant, easily recognized by the eye, and botl 

 common ; but which offer to my examination no clear 

 characters for written distinction as species. A frequenc 

 weed of the Highland corn fields, as well as in those of 

 England ; and often seen in coppices and on hedge-banks, 

 where the ground had been lately disturbed.

Native. Agrestal. Gradually disappearing towards the 

 two latitudinal extremities of Britain, though pretty fre- 

 quent over a large intermediate area. If not deemed 

 sufficiently general to be correctly referred to the British 

 type, it must be assigned to the Scottish rather than to the 

 English ; for its chief prevalence is in provinces 8 to 16. 

 Perhaps the estimate might have been carried up to 60 

 counties. The distinctness of this species has been doubted; 

 but, according to the Rev. W. A. Leighton, its seeds pro- 

 duce only plants of its own kind. (See Mag. Nat. Hist, 

 viii. 635.) While this unchanged reproduction, through 

 one or few descents, cannot clearly establish specific dis- 

 tinctness, it affords an argument presumptively in favour 

 thereof.
