Postelsia aT 
i. Warge=open beach: 
Along the front border of the large open 
beaches. the association of plants almost un: 
iversally met with is composed of the following 
Species:— 
Juncus lescurit Argentina anserina grandis 
Ammodenia major Trifolium heterodon 
This region of the beach is subjected to 
occasional flooding by high waves even in sum- 
mer, and during the frequent winter storms 
bears repeated inundation. 
Farther back upon what might well be termed 
the driftwood area of the beach, the vegetation 
consists of a mixed society of so-called weeds. 
The seeds of these hardy plants at first carried 
in by various agencies, have found lodgment in 
the tangle of logs and debris and it is largely 
through the aid of this barrier that a vigorous 
association has been built up and flourishes. 
The species most commonly established over 
such an area are:- 
Elymus mollis Chamaenerion angustijolium 
Festuca jonesit Conioselinum gmelint 
Bromus secalinus Galium aparine
