DIDYN. GYMNOSP. 181 



Four to five feet high. Flowers purplish red, with a linear subhispid 

 brae tea at the base. 



3. M. gcntilu (lushy red Mint), flowers whorled, leaves petio- 

 late ovate serrated snbglabrous, " stem much branched spread- 

 ing" (Sm.\ pedicels and lower part of the cal. glabrous teeth 

 hairy. Light/, p. 305. E. B. t. 2118. 



HAB. Sides of rivers and waste places, but rare, Dr. Parsons. Bank

 Banks of Moftat water, below Carrifrew, Dr. Walker. Fl. Sept. I/ . 



" Stem 12 18 inches high, very bushy in consequence of the nume- 

 rous, opposite, spreading branches :" and this is all the character 

 that has been discovered to distinguish it from M. rubra. Surely 

 it is no permanent one ? I would not willingly decide till I see 

 plants in a growing state : but in my plants in the herbarium there 

 is not a shadow of a difference. 



4. M. arvensis (Corn-mint), flowers whorled, leaves ovate hairy 

 serrated, calyx campaniilate and clothed with spreading hairs. 

 Lig/if/. p. 306. . B.t. 2119. 



HAB. Corn-fields, not uncommon. Fl. Aug., Sept. 



The Cal. short and campanulate with spreading hairs distinguishes 

 this species. The smell of the plant has been compared to that of 

 the blue part of decayed cheese. Flowers reddish purple. I think 

 the M. agrestis of E. B. is not distinct from this. 



5. M. Pulegium (Penny -royal), flowers whorled, leaves downy 

 ovate obtuse subcrenate, stem prostrate, flowerstalks slightly, 

 and calyx very, pubescent, teeth of the latter fringed. Light).

 small frequently recurved leaves, which are both thickly covered 

 with short hairs. Flower pale purplish. Much employed in medi- 

 cine, and has a powerful smell,
