vi] MARSH AND AQUATIC ASSOCIATIONS 149 
At altitudes from 1000 feet (805 m.) downwards many of 
the Juncus swamps are rich in species: above that altitude, 
the swamps become floristically poorer and poorer. 
The full list of plants of the Juncus swamps is a very long 
one, in which respect the association resembles most other 
mixed or unstable or kinetic associations. In the following 
list the plants more characteristic of peaty localities are printed 
in italics :-—
