A SURVEY OF THE LOWER TEES l\IARSHli:S • 1 29 



after the joint dominancy of Glycerin and Salicornia, Aster 

 gains a footing, followed hard by Staiice liinonium, until at 

 length we have developed a sub-association, which is a form 

 of Glycerietum worthy of the term Glycerio-Staticehini. In 

 this we find 



Glyceria maiitiiTia (/ Suaeda inaiitima 



Statice limoniiini f-hi Armeria inaritinia 



Aster tripolium o a Spers^ularia mar^inata r 



Salicornia europaea (agg. ) a 'rri<,'locliin inaritimmn J 



Next in order arises the Staticetum, occupying the main 

 body of the upper marsh and obviously the most stable of the 

 varied associations liable to tidal immersion ; this resembles the 

 stage just passed in composition, but the frequencies are very 

 diverse. List : —

Gradually, as we proceed beyond the limits of immersion by 

 all but the highest spring tides, whether toward the Creek or 

 toward the edge of the marsh, both on the north and on the 

 south, this community glides by degrees into an Armerietum 

 differing very widely from that referred to above. Its more 

 open nature is indicated, especially on the south side, by the 

 presence of the various Salicorniae, and the general aspect of 

 the community as a whole contrasts greatly in the mind's eye 

 with the close dark green turf of the Armerietum higher up 

 the Creek. Its usual elements are : —

This, and similar associations, present a pretty sight as they 

 fringe the marsh with pink in June — a sight only equalled
