THE FLORA 415 
“<The plants of the slopes are in many respects the most 
interesting. The majority of them occur as_ strongly 
developed individuals, which here appear to thrive per- 
fectly, and apparently can ripen their seeds annually. 
This naturally is true of the good localities, namely, of the 
slopes that soon become free from snow. Here one has an 
opportunity of being able to observe the remarkable in- 
fluence of the sun’s rays. Slopes, that a short time before 
were covered with snow, a few days later are adorned with 
several flowers; the development of these can proceed so 
rapidly that one soon finds fruit as well, as in the case of 
Draba. Here one sees sometimes quite blue mats of Pole- 
monium pulchellum, or red ones of Sazifraga oppositifolia, 
with a varied mixture of other tints, yellow, white, green. 
When the plants of the slopes occur in the plains, 
they are not usually so well developed as on the slopes, but 
the difference in this respect is much greater in some 
plants than in others.’ ” 
The plants growing on these slopes are for the most part 
more flourishing individuals of the same species that are 
found on the surrounding tundra. I myself noticed only 
a few that seemed confined to these or similar situations: 
Ranunculus pygmeus, R. hyperboreus, Linnea borealis, 
Gentiana nivalis. Many others might probably yet be 
discovered by careful attention to the influence of this 
particular situation. 
Such aspects of the vegetable growths of Labrador as 
have thus far been described may be considered as excep- 
tional. The predominant form of vegetation on or near 
the coast is that of the true tundra itself. Its appear- 
ance as it occurs throughout Labrador I cannot better 
describe than in words which I have already used: '—
