of the vegetation, as this climate tends to “ Cosmopolitanism,” 
vegetation of very different range occurs together. 
These 
two factors constitute a great difficulty in the study of the ecology 
Types of 
vegetation separated in a warm climate in several altitudinal belts 
converge and mix in cooler regions, because the basal vegetation 
extends northwards and at the same time the mountain vegetation 
descends more and more. Ina continental climate the vegetation 
lines run far apart and each belt can easily be studied separately, 
while in the oceanic climate the lines merge ; for instance the alpine 
vegetation descends and mixes with montane or even with coastal 
plants. 
To get the key for the cool oceanic Killarney woods we must 
look for comparisons in a little warmer or a little less oceanic region.
