brackish marsh ordinarily support a rank growth of coarse 

 sedges, notably Scirpus occidentalis, S. campestris paludosus, 

 Carex maritima, and C. salina. These, singly or collectively, may 

 constitute the pioneer association-type. On the higher parts of 

 the marsh the predominant forms usually are Junciis balticus 

 littoralis and Agrostis alba maritima. Other fornis which may 

 be more or less abundantly represented in brackish marshes are 

 listed below.
