latus, J. obtusiflorus, etc.) or sedges. These plants often 
grow thickly to the exclusion of all others. In the more 
open parts some plants found also in the marsh occur— 
e.g., Ranunculus Flammula, Comarum palustre, Hydro- 
cotyle, Stellaria uliginosa, Anagallis tenella, Menyanthes 
trifoliata, Parnassia palustris, Orchis latifolia, etc. But 
many others characteristic of sour soil are abundant— 
e.g., sundews, butterworts, Vaccinium Oxycoccus (cran- 
berry), Andromeda polifolia, Erica Tetralix, Salix repens, 
Narthecium ossifragum (bog-asphodel), Selaginella selagi- 
noides, Molinia ceerulea, etc.
