1903] VEGETATION OF THE BAY OF FUNDY MARSHES 365 
A perennial herb of somewhat fleshy structure, not occurring 
in as salt places as its appearance would imply. 
All of the members of this association are characterized by a 
moderately xerophytic structure, but with little provision for air 
storage, explaining well their position as occupants of the high 
marsh, which is rarely overflowed and from which a part of 
the salt at least is removed by superficial drainage. 
The dominant members of the association are the Spartina 
(fox-grass or mezotte) and the Statice, with the Puccinellia and 
Plantago as important secondary members, and Festuca, Jun- 
cus, Triglochin, and Hordeum as less important, while Glaux is 
subordinate. The Spartina is the most important of all, forming 
the greater part of the association on the high marsh, and occur- 
ring here and there, especially in the slight depressions just out- 
side the dikes (fig. rg), in large stretches unmixed with the others. 
In such places it forms a dense close turf. Elsewhere the Sta- 
tice occurs intermingled with it (figs. 9, 13,74), probably in such 
positions deriving some protection from transpiration for its 
broad leaves by the shade of the Spartina, but the Statice is especi- 
ally important as the marginal member of the association particu- 
larly in its advance upon new marsh (figs.9, 10,71). It advances 
upon and displaces the Salicornetum, and then engages the Spar- 
tinetum advancing up the beach, the two associations mingling 
along the line to some extent (figs. ro, 17). The line of con- 
tact between these two represents one of the lines of competi- 
_tion to which I have given much study, with no results of value. 
When advancing in this way upon new marsh the Statice often 
forms so distinct a band that one is tempted to assign it to an 
association by itself, the more especially as it also so often 
occurs in a band on the angle of the dikes just inside of the fox- 
Srass (fig. 15); but the luxuriance with which it grows along 
with the fox-grass shows it to be properly a member of the 
Same association with that, while its distinctness on new marsh 
is plainly due simply to its more rapid power of spread. Closely 
following and intermingling with the Statice comes the Plantago, 
which also sometimes exhibits an indistinct band by itself, par- 
ticularly between fox-grass and Statice. Intermingled with the
