1903] VEGETATION OF THE BAY OF FUNDY MARSHES 359 
Britton.—Apparently has no local name in the marsh country. © 
Occurs to some extent with the Suaeda and Salicornia but be- 
longing to less salt and wet places than either, and hence 
characteristic of the very highest and driest spots of the wild 
marsh ; especially prone to wander inside the dikes on low places 
and along the roads. 
Vegetation-form nearly identical with that of Suaeda, but 
smaller, more profusely branched and decumbent, and more leafy, 
with the leaves somewhat more slender. It is of a brighter 
green than the preceding, and unlike any of the preceding, bears 
pale pink or whitish star-like apparently entomophilous flowers. 
ATRIPLEX PATULUM L., vars. hastatum Gray and “ittorale Gray. 
Atriplex patula L. and A. hastata ..— Appears to have no recog- 
nized local name. Occurs with the Salicornia and Suaeda, 
especially on their drier side, when it is not much taller than 
they, as a rather inconspicuous member of the Salicornetum, but 
extends also upon the dikes, when it occurs as a band, usually 
on the inner, lower side of the dikes; extends also within the 
dikes, especially upon newly flooded marsh, where it may 
become waist high. 
The species represents a distinct vegetation form, a fibrous- 
rooted annual with erect stem and petioled hastate (var. hasta- 
tum) or linear (var. “ittorale) leaves, the whole plant varying in 
size from a few inches on the saltest places to near 3% (1™) on 
newly flooded marsh. The plant exhibits in its vertically adjust- 
able leaves which are extremely well marked in the young state 
on the salt marsh, in its thick cuticle, dense palisade, and its 
abundant covering of scales (giving it its characteristic scurfy 
or mealy appearance), xerophytic adaptations, adapting it to its 
halophytic habit. Its root-hairs endure nearly 40 per cent. salt 
water without plasmolysis. There appears to be no constant 
relation between the distribution of the linear and the hastate 
leaved forms and the environment, though each kind occurs as 
a rule largely by itself. It is wind-pollinated and wind-dissem- 
inated. 
The chief characteristics of this association as a whole, its 
rapidity of appearance on new marsh and its ability to endure
