Fig. 77. — Loch nan Gead’as, with a zone of Castalia speciosa, behind which are 
belts of Equisetum limosum, Carex rostrata, Comarum palustre, Myrica 
Gala, etc. 
Fig. 78. — Sandy flat at the east end of Loch Ruthven, showing the moorland 
vegetation encroaching over the sand. The foreground is thickly clothed 
with Calluna vulgaris, Myrica Gala, Juncus squarrosus, Nardus stricta, 
Deschampsia flexuosa, Juncus effusus, etc. Nearer the water the plant- 
covering is thinner, then isolated clumps and plants finally give way entirely 
to sand.
