vegetation has gained the mastery over a large area, for 

 the time being, at least. 



Dune Grassland. — A dune-grassland-like, close and 

 varied vegetation occurs in this area, especially to the 

 east of the loch proper. Grasses grow luxuriantly, the 

 chief being Holcus mollis, Linn. ; Holcus lanatus, Linn. ; 

 and Aira, spp. Here Thymus Serpyllum, Linn., is sub- 

 dominant, and Lotus corniculatus grows in great abund- 

 ance with Viola canina ; Myosotis versicolor, Sm. ; 

 Veronica officinalis ; Senecio Jacobaea ; Bellis perennis ; 

 Statice maritima ; Luzula campestris ; Taraxacum 

 palustre, DC. ; Cardamine pratensis, Linn. ; Poly gala 

 vulgaris, Linn. ; Plantago lanceolata ; Potentilla An- 

 serina ; Erophila verna, E. Meyer ; and Viola palustris, 

 Linn. Where the vegetation grows up on to the surround- 

 ing dunes, Filago germanica is frequent. 



Within the marginal belt of the loch is a dense marsh of 

 Potentilla palustris, Scop. The vegetation about this part 

 has assumed the nature of a felt from out of which the 

 inflorescences of the following species rise : Eriophorum 

 vaginatum, Linn. ; Eriophorum angustifolium, Roth. ; 

 Epilobium palustre, Linn. ; Galium verum ; Galium 

 palustre, Linn. ; Galium tdiginosum, Linn. ; Myosotis 

 scorpioides, Linn. ; Salix aurita ; Cardamine pratensis ; 

 Trifolium pratense, Linn. ; Drosera rotundifolia, Linn. ; 

 Caltha palustris, Linn. ; Senecio Jacobaea ; Prunella 

 vulgaris, Linn. ; Viola palustris ; Veronica scutellata, 

 Linn. ; Pedicularis palustris, Linn. ; Pedicularis sylvatica, 

 Linn. ; Iris Pseudacorus, Linn. ; Juncus effusus, Linn. ; 

 Eleocharis palustris, Roem. et Schult. ; Carex Goodenowii ; 

 Equisetum limosum, Linn.; Ranunculus repens, Linn.; 

 Viola canina; Spiraea Ulmaria, Linn. Although the above 

 is roughly the order of frequency of general occurrence, it 

 will be seen by the map that certain are dominant locally. 



Associated with these angiosperms are Philonotis 

 fontana, Brid. ; Plagiothecium denticulatum, B. et S. ; 

 and Ceratodon purpureus. 



Low-growing Betula tomentosa is frequent along the 

 south-eastern margin. 



On the south is a dense mass of Phragmites communis, 

 Trim, and another of Typha latifolia, Linn.
