A somewhat similar development of the Jimcm association also 

 occurs not infrequently in the Vlex Gallii area, where the drainage is 

 bad, and the ground becomes waterlogged. Here we find the associa- 

 tion composed as follows : — 



JuifCUS EFFUSTJS. 

 J. ACUTIFLORTJS . 

 J. SQUAEROSUS. 



Ranunculus Flammula. 

 Viola palustris. 

 Hypericum elodes. 

 Drosera rotundifolia. 

 Hydrocotyle vulgaris. 

 Erica Tetralix. 

 Anagallis tenella. 



Pinguicula vulgaris. 

 P. lusitanica. 

 J^arthecium ossifragum. 

 Potamogeton polygonifolius. 

 Carex stellulata. 

 C. glauca. 

 C. flava. 



Molinia cserulea. 

 Sphagnum spp. 



Again, in the same ''G" area, interesting wet spots occur here 

 and there, especially on the northern slopes of the Two-rock group, 

 which show the following composition : — 



Juncus acutiflorus. 

 J. lamprocarpus. 

 J. squarrosus. 

 J. supinus. 

 Carex flava. 

 C. glauca. 

 C. stellulata. 

 C. binervis. 

 Nardus stricta. 

 Calluna vulgaris. 



Scabiosa succisa. 

 Viola palustris. 

 Narthecium ossifragum. 

 Drosera rotundifolia. 

 Pedicularis sylvatica. 

 Ranunculus Elammula. 

 Potentilla Tormentiila. 

 Lycopodium Selago. 

 Polytrichum. 

 Sphagnum. 



This type of the association may be looked upon as forming a sort 

 of transition from the more typical high-level Juncus- Polytrichum 

 association to that about to be described. 



The second type of Juncus association is developed chiefly on the 

 lower grounds, and is of a marshy-pasture nature. ]N"o attempt has 

 been made to indicate on the map published herewith the numerous 

 small areas, consisting of badly-drained fields, which occur in the 

 agrarian zone. Where, however, there are large areas of marshy 

 ground, as, for instance, south of Brittas, it has been possible to include 

 them on the map.
