specimens of Myrica are found in the thicket formation, but as far as in- 
spection showed it does not grow as a zonal plant. Associated with the 
waxberry bushes at Sea Side Park is the ubiquitous sand grass (Ammophila), 
an occasional golden-rod (Solidago sempervirens) and a prostrate growth ot 
Euphorbia folygonifolia, but that is all. At Ocean City, Sfrophostyles hel- 
vola, Panicum virgatum, Baccharis halimifolia, Rhus radıcans are mixed to- 
gether by reason of the parallelism of the three dunes which occur there, and 
Miyrica, therefore, becomes an element of the dune complex. 
Hudsonia Strip (the Dune Complex). This strip is of especial interest. 
The topography is kaleidoscopic. The dunes are constantly changing their 
shape, being blown away on one side and built up on the other. The hollows 
between them are filled up and new valleys are scooped out by the resistless 
action of the wind. This is true of this belt along the entire New Jersey 
coast, where it is a dominant feature of the landscape, but the change is not 
so rapid in some places as in others. Some of the dune complexes change 
very slowly, others more rapidiy; some, it may be, have become stationary. 
At Sea Side Park, the dune complex extends from the limits of the Myrica- 
Strip already defined to the Juniper-Strip of the typic thicket formation. At 
South Atlantic City it does not exist; at Ocean City it is an area of esta- 
blished dunes clothed with a variety of plants; at Wildwood it is a narrow 
area of a low frontal dune and a hollow immediately behind it, encroached 
upon by tree growth, and is, therefore, not clearly demarcated at either of 
the places last mentioned. 
At Sea Side Park, where it typically exists, there is not an established series 
of dunes, but the change is a slow one, motion being arrested by the cha- 
racter plant, Hudsonia tomentosa, which forms clumps or cespitose clusters 
closely set together on the top and sometimes the slopes of the slowly moving 
dunes. Associated with this low growing perennial herb are found Solidago 
sempervirens, Rhus radicans, trailing over the ground and with an etiolated 
appearance, expressive of its struggle for supremacy. Linum medium, Lechea 
maritima and others, such as Ampelopsis, are occasional intruders on the more 
established dunes ’). 
Upon a transversely placed dune exist isolated trees of the following species 
in considerable numbers, but nowhere growing together, except it may be in 
companies of twos or threes, usually, however, standing alone: Ozereus tiel- 
Jolia, is a small tree of dense growth; ler opaca is strong-growing and dar 5 
green in color; Ouercus phellos, the willow oak, forms a dwarf tree about four e 
feet high; Vaccinium corymbosum, with smooth leaves, and V. atrococcum, with 
densely pubescent leaves and gnarled form, both loaded with berries, were 
found to exist here, with Aalmia angustifolia, and Rubus canadensis, trailing |

1) Prunus maritima L., the beach plum, forms by its upward growth small dunes, comparatively 
steep. It usually grows in isolated patches on the slopes or summits of the dunes, near the center 
or inside margin of the dune complex.
