In our country Lobari'a liiiita prefers alpine and subalpine positions, 

 but it also descends to the level of the sea. In Northern Norway it is 

 frequenth' associated with Andromeda tctragoiia. 



Lobaria liuita is common in Northern Norway. In Southern Norway 

 there are onh' few and scattered stations. Only recorded from Findo near 

 Stavanger in Western Norway, Havaas never succeeded in finding it in 

 Western Norwa}'. 



This distribution is remarkable, for otherwise it is no arctic, or even 

 a northern European species. It is on the contrary evidently more frequent 

 and better developed in Southern than in Northern Europe. 



It is an eastern species in Norway. This might perhaps indicate its 

 route of immigration : That it should have immigrated from Sweden and 

 Finland and crossed our frontier at several places. Its greater frequency 

 in Northern Norway might be incidental, or indicative of an earlier immi- 

 gration, or of better conditions of life. Its distribution in other (southern) 

 countries makes the last suggestion the least probable one. 



The plant from SoUi might most probably be referred to var. compli- 

 cata Th. Fr. Spitsb. p. 12. 



Apothecia are not seen from Norwa}-. — There is no colouring with 

 KOH or Ca CI.2 O,, or by these agents united. 



The specimens from Southern Norway differ somewhat from northern 

 specimens: the former ones are smaller with narrower laciniae, approaching 

 habitually to Lobaria piilmoiiaria.
