100 Mr. R. Spruce on the Musci and Hepaticce 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 especially 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.
