I had, unfortunately, no time or occasion for digging out in any of all the peat-bogs in which the Urjankai country abounds, and which would no doubt bring to hght many interesting facts. The bogs were now frequently more or less dried up, and the original vegetation had been gradu- ally mixed up with other plants, or, in the process of time, wholly expelled by these. Fig 43.

In similar places were often to be found common copse-wood of Betula humilis, Betula rotundifolia, or in places, high and well grown firs and various Salices, and with an undergrowth of divers species of grasses and sedges, especially Carex caespilosa, which might form tussocks to over one meter high, Vaccinium Myrlillas, Vaccinhim vitis idaea, and besides, also very commonly Vaccinium uliginosum subspec. imberbe nov. subspec, Rubus arcticus, 71.
