Comparison of Low-Arctic Elements in the Flora of Greenland and Eastern North 

 America as to Adaptations to Long-distance Dispersal. 



Further explanation in text. 



of Labrador as a basis for comparison results in some over-representation of 

 types adapted to long-distance dispersal, but the difference is not statistically 

 significant. This is, however, probably due to the higher representation of 

 types adapted to long-distance dispersal within the more temperate elements 

 in the flora of Labrador. 



From the data presented the following conclusions can be drawn: 



1. The Arctic-Sub-Arctic flora in general and the Amphi-Atlantic elements 

 in particular are under-represented in types adapted to long-distance 

 dispersal.
