When Phragmites is developed in dense pures strands in shallow water it is completely sociably exclusive. In the drier portions or higher portions of the marsh there is unusually a carpet of moss or Eleocharis acicularis on the ground among the stems of the facies.

One of the commonest facies of this stage in the sucession is the smartweed - Polygonum hartwrightii , P. exsertum , P. amphibium are often seen here in such confined variation that it is indeed impossible to clearly differentiate between the three species.
