178 THE STORY OF PLANT LIFE 



Galeopsisy LeonumSy Lamium, Ballota. In the Ajug- 

 oideae there are four stamens, parallel, ascending, 

 exserted, two upper shorter. The nutlets are connate, 

 the base oblique, reticulate and rugose, and this tribe 

 includes Teucrium and Ajuga. A type of each is 

 described here or in the Introductory Volume, Mentha 

 hirsuta. Salvia Verhenaca, Nepeta hederacea, and Ajuga 

 Chamcepitys being described hereafter. 



Hairy Mint (Mentha hirsufa). 



Called also Water Mint and Horse Mint (and M. 

 aquatica), Hairy Mint is characterised by being more 

 clothed with rigid hairs than other species, and it is a 

 moisture-loving plant, fond of water (h&nce aquatica) , 



As a universally common plant. Horse Mint (so 

 called because of its coarseness) is found in all parts 

 of the British Isles up to the Orkneys. It grows at 

 an altitude of 1500 ft. in Yorkshire. It does not 

 appear to be so common, however, in Scotland. It 

 is found in the Channel Islands. 



As denoted by the names Water Mint (and aquatica) 

 it is a moisture-loving plant. The habitat is wet 

 ditches, marshes, the edges of streams and rivers, or 

 wet places generally. It is found on clays and loams 

 in neutral grassland, where there is a rush association, 

 as well as on limestone in ashwoods, where there is a 

 marshy tract. 



Ascending or prostrate in habit, the plant is much- 

 branched. As the names given above imply it is 

 softly-hairy. The stems are four-angled and tall.
