The ferns are not so gregarious as they are lower down, 

 not even the oracken, though it becomes so again higher up. 

 The following are met with : — 



Pteris aquilina Lastrcea Oreopteris 



Lomaria Spicant L. Filix-mas 



Athyrium Filix-fcemina L. dilatata 



The list of plants found in the swamps towards the clough- 

 head is a lengthy one, and on the whole shows but little 



variation from place to place. The chief 

 Clough difference is produced by altitude. Lower 



Swamp. down Herb Robert, Figwort, Valerian, 



Angelica, Wall Lettuce, Meadow Sweet, 

 Cardamine flexuosa and Chrysosplenium oppositifolium enter into 

 the association, whilst nearer the moors they give place to 

 Marsh Violet, Sundew, Butterwort, Cranberry, Bog Asphodel, 

 and Potamogeton polygonifolius. The birch and willows (S. 

 Caprea, S. aurita and S. repens) are the only shrubs that 

 endure the excessive moisture, unless the cross-leaved heath 

 be included with them. 



The general list of these swamp-plants is as follows : — 



Ranunculus Lenormandi Myosotis ccespitosa 



R. Flammula M. repens 



R. repens Veronica Beccabunga
