Native. Agrestal, Inundatal. Said to be very common 

 in Moray ; and it is the only species which I have observed 

 in the mountain valleys of the Highland provinces. The 

 various species of Menthaare much more characteristic 

 of the English than of the Scottish flora. To the north 

 and west of the Caledonian Canal only two species occur, 

 and those very locally. None are enumerated in the Flora 

 of Shetland, except M. viridis as an introduced plant. 

 None were observed in the Outer Hebrides, by Balfour and 

 Babington. Nor do I find any species of this genus men- 

 tioned among the plants which were observed by myself in 

 Caithness, Sutherland, or Western-Inverness, M. arvensis, 

 however, occurs in Faroe, and throughout Scandinavia. 

 Possibly the county estimate of 75 might have been more 

 correct for this and M. hirsuta.

Native. Inundatal. In Babington's Manual this is en- 

 tered as a species found in England, Scotland, and Ireland . 

 I fear that Scotland is an error ; as I know of onl}- two 

 habitats on record, and probably both ought to be rejected. 

 Mr. W. Brand gave me a sjjccimen picked near the Church 

 of Birnie, where the Rev. G. Gordon deems it certainly
