 gradually assuming the condition of a steppe. In this 

 respect, Lin dblom's observations on the desert of the By gle- 

 an d Hekle-Fjelds, or the most southern part of the high- 

 lands, which were made many years ago, but are again 

 brought forward in the present memoir, are instructive. 

 The predominating plants of some tracts in this part, 

 e. g. between Siredal and Lysefjord, are Molinia ccerulea 

 and Solidago virgaurea, and these displace all others. 

 The alpine plants of this region, as shown by the following 

 list of them, also grow in Hardanger, and do not resemble 

 those of the Brocken or the Sudeten, to which, among the 

 whole of the Scandinavian mountains they are most nearly 

 situated.

The second section of Lindblom's memoir treats of the

 theory, ought to be more common on the western coast
