As noniially developed this association is always confined to a nar- 

 row strip a meter or two wide bordering on the water. But it is one 

 of the associations which have become greatly extended since the clear- 

 ing of the country. In the cleared lands, however, it does not develop 

 in its purity, but becomes a meadow covered with Panicum latifolium, 

 together with various sedges, rushes, and other common meadow and 

 pasture plants.
