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, Carcx livida, Carex 

 sitchensis, Carex sterilis cephalantha, Carex 

 howellii, Carex pauciflora, Eriophorum poly- 

 stachyon, Scirpus caespitosus, Rynchospora alba, 

 J line us paiicieapitatns, J uncus ejjiisiis. A num- 

 ber of heaths occur typically in these places such 

 as Kalmia glauca, Ledum groenlandicum, and 

 Oxy coccus palustris. With them are generally 

 associated Empetrum nigrum and Myrica gale. 

 Particularly frequent are Drosera rotundifolia, 

 Gentiana douglasiana, Hypericum anagalloides, 

 Sanguisorha media, Limnorchis stricta and Lim- 

 norchis graminijoUa. Of herbaceous species 

 which are of less universal distribution one meets 

 with,

Plantago macrocarpum Apargidium horeale
