is very likely that these places were originally 
typical Sphagnum bogs and that gradually 
through the ages as they build themselves up 
higher and became drier other plants wandered 
in until the present complex has been built up. 
Besides the various species of Sphagnum and 
other mosses, one finds here turf building types 
like Agrostis aequivalvis, Carex livida, Carex 
sttchensts, Carex sterilis cephalantha, Carex 
howelli1, Carex pauciflora, Eriophorum  poly- 
stachyon, Scirpus caes pitosus, Rynchospora alba, 
Juncus paucicapitatus, Juncus ejjusus. A num- 
ber of heaths occur typically in these places such 
as Kalmia glauca, Ledum groenlandicum, and 
Oxycoccus palustris. With them are generally 
associated Empetrum nigrum and Mvyrica gale. 
Particularly frequent are Drosera rotundifolia, 
Gentiana douglasiuna, Hypericum anagalloides, 
Sanguisorba media, Limnorchis stricta and Lim- 
norchis graminijolia. Of herbaceous species 
which are of less universal distribution one meets 
with, 
Coptis as plentjolia Faurta crista-galli 
Plantago macrocarpum A pargidium boreale
