THE HIGH ALPINE FLORA OF BRITAIN 165 



in English feet ; in the second column, the series begins 

 with the loftiest summit, then in descending order until a 

 thousand metres is reached, the heights being given 

 in metres. Where, as in several cases, the mountain forms 

 part of a county boundary, it is included for the purpose of 

 this List in the larger county. Thus, several peaks on the 

 Perthshire border are included in Argyllshire, and most of 

 those on the Banffshire border are included in Aberdeen- 

 shire or Inverness-shire. The greater part of Ben Macdhui 

 is in Aberdeenshire, but as Corrie Etchachan, high up on 

 the northern slope (frequently mentioned as a locality for 

 Alpine plants), as well as the actual summit of the mountain, 

 are in Banffshire, it is for convenience included in the latter 

 county. Ben Lawers, on account of the accessibility of all 

 points of its area, is probably the best known mountain in 

 the Highlands. The portion of it that comes within the 

 scope of the present flora begins at 700 ft. (perpendicular) 

 below the summit ; and the earliest records of plants 

 gathered near the top are those of James Dickson, J. T. 

 Mackay, W. MacRitchie, Robert Brown, and Don, from 

 1789 to 1794. Some indication of the limited scope of 

 this high Alpine flora may be illustrated from the case of 

 Perthshire. The area of Perthshire is given as 2588 

 square miles, but the area of the county above 3000 ft. is 

 estimated at only 16 square miles. Those mountains are 

 starred (*) which are specifically mentioned in the following 

 pages. It is thus evident that much remains to be done 

 in working out the distribution of plants on the higher parts 

 of the Scottish mountains.
