districts and at tlic iiil,iii<l 1 rid of the fjords, but not on tiie coast. Quite 

 the same is the case in Soullici-n Norway. Its southern limit is Nordby a 

 little south of" Kristiania. It has not been recorded from Western Norway. 

 On the whole it is a continental species of chiejly northern and eastern 

 (iisl)il)iili(iu. \u these districts it is quite common. 



Parnielia /randans has only been recorded as a saxicolous plant. It 

 prefers moist places, as stones at the strands of the lakes, and the like, 

 but it is by no means bound to such stations, I have also found it on dry 

 sunny rocks. Not seen on chalk. 



It prefers subalpine and alpine positions, it is most frequent about the 

 tree line, not known from the highest mountains and less common in the 

 lowlands. It is not known whether it ascends to the summits of the highest 

 mountains, the 'gaiser' in Finmarken, but it ascends to the summit of the 

 lower mountains in Finmarken, such as Rautasvarre and Store Raipas in 

 Alten.
