Throughout the Teutonic region of the 
Alps the word Alp is used specifically for the upper pastures where 
cattle are fed in summer, but this region is held to include the whole space between the uppermost limit of 
trees and the first appearance of permanent masses of 
snow.  It is here that the characteristic vegetation of the Alps is developed in its full beauty and variety.  
Shrubs are not wanting.  Three 
species of 
rhododendron vie with each other in the brilliancy of their masses of 
red or 
pink flowers; the common 
juniper rises higher still, along with three species of 
bilberry; and several dwarf 
willows attain nearly to the utmost limit of vegetation.  The upper limit of this region coincides with the so-called limit of perpetual snow.
