 Missouri Bot. Garden. II. p. 59—108. 6 Fig. 1915.) 



This papers contains an account of the results at which histo- 

 rical phytogeography (the investigation of the changes that in the 

 course of time have taken place in the Vegetation of a country) 

 may be said to have arrived as far as Norway is concerned. 



The terrestrial plants of Norway may be divided into five 

 zones, according to their dependence of the mean temperature of 

 the Summer. These zones are indicated by the upper limit of a 

 characteristic species of plant. 



1) The Quercus peduncidata zone, 2) The Pinus süvestris zone, 

 3) The Betula odorata zone, 4) The zone of dwarf willows, 5) The 

 Liehen zone. 



The second part of the paper contains a review of the different 

 opinions on the immigration of the norvegian flora. The author 

 does not consider it probable that there was an interglacial direct 

 land connection between England and Norway. Although con- 

 sideral portions of the North Sea which are now covered by 

 water, were clothed with forest, the deep norvegian Channel out- 

 side the coast of Norway has certainly been in existence ever 

 since the Last Glacial Period. Jongmans.
