Hydrocotyle vulgaris, Linn., grows all around the loch. 



To the south-west in the valley the ground becomes 

 drier and more and more composed of pure sand. One 

 small damp patch has Myrica Gale, Linn., dominant and 

 associated with Rosa, sp. ; Valeriana officinalis, Linn., 

 and Plant ago lanceolata. 



Alnus rotund if olia and Calluna vulgaris are associated 

 a drier habitat. 



Erica Tetralix is locally dominant with various associates. 



Carex Goodenowii and Teucrium Scorodonia, Linn., are 

 abundant on the more or less open vegetation of the sand. 

 Potentilla Anserina; Achillea Millefolium, Linn.; Vicia 

 august (folia, Linn., are frequent. Scabiosa Succisa, Linn. ; 

 Pyrola media ; Luzida sylvatica, Gaud., also occur. 

 Polytrichum commune is dominant in many situations. 

 Lycopodium clavatum, Linn., is locally abundant. 



(b) West Loch Basin. 



This is south-of-west from Buckie Loch and just outside 

 the western end of the valley in which the latter lies. The 

 elevation of the sands around is low. About the lochs 

 proper are bogs and marshes like moss-hags, among which 

 are mingled low ridges and flats of fixed and also of 

 shifting sand. On the sandy outskirts on the north side 

 are Ulex europaeus, Linn., growing in low mats; and low- 

 growing Betula tomentosa. Salix repens stretches out on 

 to the sands on all sides. Equisetum arvense, Linn. ; 

 Taraocacv/m officinale ; Veronica officinalis; Viola canina; 

 Cardamine pratensis, also occur. Carex Goodenowii; 

 Hylocomiv/m triquetrum: Hylocomium squarrosum; 

 Hypnum cupressiforme ; Brachyikecium purum, Dixon, 

 largely appropriate the sand about the marshes. Numerous 

 sudden changes in the flora are seen in this region, in accord- 

 ance with the intimate mixture of marshy and sandy habitat. 



Blechnum Spicant, With., grows on the sides of the sandy 

 ditches and mounds, Spiraea Ulmaria by the bog edges, 

 Equisetum arvense in the bogs. 



In the water are Typha lot if olia; Hippuris vulgaris, 

 Linn.: Lemna minor, Linn. 



[On the dry banks near the marsh are Cytisus scoparius ; 

 Luzida multiflora, DC. ; Empetrum nigrum, Linn. ;
