soras the banks of Langton woods. It is, I am persuaded, a good 

 species, though it may be difficult to give technical marks. No one 

 who has seen it, will deny its claims, or unite it with M. arvensis" 

 Mr Brown. 



SCROPHULARIA AQUATICA Water Fif/wort. On the sides of the 

 Whiteadder below Claribad mill, plentiful ; Mr R. Dunlop. 



MENTHA SYLVESTRIS Horse Mint. In the neighbourhood of Blan- 

 erne, abundant ; Mr Dunlop. 



MENTHA CRISPA, Linn. Side of Wooler Water near Coldgate mill ; 

 and about one mile and a half above Langleford, on the borders of 

 a rivulet flowing down from the Cheviot, and near its junction 

 with the Wooler Water ; Mr Mitchell. A specimen of this addition 

 to the British Flora being sent to Mr Winch, he pronounced it to 

 be the M. crispa of Linnaeus, an opinion which has been since con- 

 firmed, and it is understood that a figure of it will soon appear in 

 the Supplement to English Botany. The following extract is from 

 a letter of Mr Mitchell : " I took the mint to Mr Bennet, who has 

 the charge of the Linnean herbarium. On comparing it with Lin- 

 naeus' specimens it is M. crispa, as you mentioned : there seems to 

 be no natural habitat for it except in Northumberland, for though 

 Linnaeus gives Siberia, Switzerland, and Hartz in Germany, the 

 first of these, by a pencil note of Sir J. E. Smith, appears to have 

 been founded on a very different plant. The Swiss habitat adopted 

 from Haller is taken from specimens stated by the author himself 

 to be exotic : and the plant of the Hartz, first noticed by Weber 

 in 1774, appears, from the reference by Hoffman of Ehrharts' plant 

 to the same locality, to have been the M. crispata."
