I. INTRODUCTION. 
The only author who contributed to our knowledge of the plants 
of “Ultima Thule” was the late Mr. Thomas Edmonston, who published 
a “List of the Phanerogamie Plants, together with the Filices, 
Equisetacee, and Lycopodiacezm," in the * Magazine and Annals 
of Natural History,’ p. 287 (1841). This list I have found very 
unsatisfactory as regards the habitats and frequency of occurrence 
of the species, so much at variance with my own observations, and in 
part with the author’s own, as given in his subsequently-published 
‘Flora,’ which, coupled with several errors of determination, have in- 
duced me to put this catalogue on one side; more especially as it has 
been superseded by his ‘ Flora,’ which I have employed as a basis of 
operations. Still, at the same time, in this very list are species men- 
tioned which have no place in the ‘ Flora,’ and are iruly indigenous ; 
these are— Galium Aparine, Myriophyllum “ spicatum,” Salix herbacea ; 
also, Lotus corniculatus, Empetrum nigrum, Sparganium natans, and 
S. simplex, mentioned only in the introduction to the Flora. Ex- 
cepting the last species, I have found all the above. In addition, there 
are—Veronica montana, Tormentilla reptans, Lychnis vespertina, Fu- 
maria parviflora, Ulex Europeus, Conium maculatum, Pastinaca sativa, 
Polygonum Bistorta, Betula alba, Briza media, Arundo Calamagrostis, 
Bromus arvensis, and Lycopodium. clavatum. Some of these may have
