LABIAL^E. 23 



Vai". agrestis is a remarkable one, differing very much in habit from 

 the other forms, with the leaves broader, more rugose, and often sub- 

 cordate at the base ; of this I have seen only the specimen in Mr. 

 Hardy's collection. 



The var. prajcox has somewhat the habit of !M. sativa, but the calyx 

 is shorter, and the teeth, though longer than in the other forms of M. 

 arvensis, are nevertheless shorter than those of M. sativa. 



The var. AUionii somewhat resembles !M. gentilis, but the calyx is 

 shorter, the teeth triangular, and the corolla hairy. 



With the var. parietarufolia I am not acquainted. A specimen 

 among Mr. Hardy's mints on a sheet labelled from the station given 

 for this by Mr. Baker, is var. Allionii ; but as the specimen is not affixed 

 to the sheet, the true plant may have been displaced.

Le'aves shortly stalked, oval or elliptical, wedge-shaped at the base, 

 obtuse, repand or remotely denticulate-serrate, subglabrous or more 

 or less hairy on both sides. Flowers in whorls, Avhich are all separate, 

 beginning about or below the middle of the stem. Bracts similar to the 

 leaves, and equalling them in size, the ujipermost ones sessile, without 

 flowers ; bracteoles generally absent, when present obovate or ob- 

 lanceolate, shorter than the flowers. Pedicels puberulent or hispid. 

 Calyx puberulent or hispid, funnel-shaped cylindrical, contracted at 

 the throat in fruit; teeth lanceolate-acuminate, half as long as the 

 tube, ciliated with bristly hairs; the two lower teeth longer and 

 narrower than the others, and sepai'ated from them by a deeper sinus 

 on each side. Corolla more than twice as long as the calyx, hairy 

 without, glabrous within.
