92 The Flora of Wiltshire. 



Locality. Banks of the Avon, wet ditches, and on the edges of 

 streams. P. Fl. July, August. Area, 1. 2. 3. 4. 5. 



Distributed throughout all the Districts. Stems from 1 to 3 feet 

 high, much branched, and almost always softly hairy, although 

 some varieties become nearly glabrous. Leaves stalked, ovate or 

 slightly heart-shaped. Flowers in dense, terminal, globular or 

 oblong heads, of more than half an inch in diameter. Calyx tubular, 

 furrowed, often purplish, with fine pointed teeth, and glandular. 

 This is a very variable species, the flowers are sometimes capitate, 

 sometimes whorled, and occasionally the whorls are placed so close 

 on the extremity of the branches as to form a spike. 



6. M. gracilis, (Sm.) slender or narrow-leaved Mint. Sole, 

 Menth. 37, t. 13. 



Locality. In watery places, or moist meadows. P. Fl. August, 

 Septetnber. Area, * * * 4. * 



North Division. 



4. North-west District, " By the side of a brook near Bradford," 

 Mr. Sole. 



This appears to have been found in the above locality only by 

 Sole in 1772 ; and there is a specimen in the set of Sole's mints 

 in the possession of Mr. John Hardy of Hulme, Manchester. It is 

 a slender plant with few and distant branches, growing to the height 

 of 2 feet or more. Stems rather wiry and flexuous. This mint should 

 be again carefully sought for in the neighbourhood of Bradford. 



7. M. arvensis, (Linn.) Corn Mint. Etigl. Bot. t. 2119. Sole, 

 Menth. t. 12. 



Locality. Cornfields, especially on a sandy or gravelly soil. P. 

 Fl. July, September. Area, 1. 2. 3. 4. 5. 



In all the Districts. The short, open, campanulate calyx, covered 

 all over with horizontally spreading hairs, distinguishes this from 

 all the other British Mentha^. Flotvers reddish purple. It varies 

 much in stature, in hairiness, and in the size of the leaves. The 

 whole plant has a strong disagreeable scent, compared to that of 

 decayed cheese.
