The Alpine vegetation of Great Britain is best illustrated on the 

 Scottish mountains. Among these may be noticed the Breadalbane 

 range, embracing such mountains as Ben Lawers, Oraig-ChaiUeach, 

 Meal Ghyrdy, Ben More ; and also the high mountains on the shores 

 of Loch Lomond, such as Ben Lomond and Ben VoirUch. Another 

 rich Alpine district is Clova, in Forfarshire, embracing the mountains 

 which surround Glen Dole and Glen Fee, as well as those around 

 Oaenlochan, the highest of which is Glass Meal. The third important 

 Alpine district as regards rare plants is Braemar. In that district 

 occur Ben-muich-dhui, Lochnagar, Cairngorm, Benabourd, Ben Avon, 

 Breriach, Cairntoul, and the mountains around Glen CaUater and 

 Glen Oeander. 



In visiting these Scottish mountains, we, in the first instance, pass 

 through the region of the common plants of the country, and reach 

 the moorland district, abounding in peat, and where such plants as 

 heather, heath, and Myxica Gale form the characteristic vegetation. 

 The zone of lowland cultivation ends with Pteris aquUina, which ex- 

 tends to 1000-1200' feet above the level of the sea. Above this 

 we come to the regions of Alpine and Arctic plants. In the ascent
