In the above table the plants are rigorously arranged in the 

 order of their highest latitude ; this seemed to me to be the only 

 accurate arrangement in such a list, though it sometimes places 

 ubiquitous plants above those which are genuine northerners; thus, 

 for instance, Cystopteris fray ilk will be found above several of the 

 higher arctic plants, but a reference to the lower limit will point 

 out its true character. Again, had I consulted other authors, 

 several plants would have had their ranges somewhat altered, but 

 here, as elsewhere throughout this essay, I have relied entirely 

 upon my own observations and collections, or upon those of 

 members of our Expedition.

To this form I am inclined to refer Professor Oliver's variety of 

 ti.niraiis, "floribusminoribus, pilis calycinis pallidioribus" ('Nares 

 Voyage,' vol. ii., p. 310, ed. 1878). It flowered earlier than the 

 true /.'. nivalis, and disappeared quickly, preferring ground slusby 

 with the first thaw at a high altitude. In Discovery Bay it was 

 confined to a plain from eight to twelve hundred feet above sea
