100 Mr. R. Spruce on the Musci and Hepatice of the Pyrenees. 
begins to flourish luxuriantly. For the purpose, however, of 
estimating the climatal distribution of mosses, it will rarely be 
requisite to divide the montose zone ; and where I find occasion 
to speak of an inferior and a superior montose zone, it is to be 
supposed divided into two equal portions. 
In order to enable any one to compare more completely the 
distribution of plants in the Pyrenees with that of the rest of 
Europe, and espécially with that of our own islands, I add the 
names of several plants which I have myself observed in the. 
various zones, of which many of them have appeared to me cha- 
racteristic.
