virginiana, Pinus rigida, Morus rubra (see fig. 23), while as lianes may be 
mentioned Ampelopsis, Vitis labrusca and aestivalis, Tecoma radicans, which 
reminds one of the dunes on the seashore of eastern Virginia, where the 
trumpet creeper abounds with Smilar rotundifolia. As the sand blows in 
about the trees, these lianes are covered up with the trees until the tops of 
the trees only are exposed. The lianes then take root and spread out in all 
directions circumferentially a distance of many feet from the tree which, now 
dead, formerly supported them. 
The presence of so much wood undergoing decay accounts for the 
growth of the fungi found by the writer in the pure (?) sand of the dune

Fig. 23. High dune at Piermont, Seven-mile Beach, New Jersey encroaching on a forest con- 
sisting of Juniperus virginiana L., Ilex opaca Ait., Nyssa sylvatica Marsh., QOuercus Iyrata Walt., 
cer rubrum L., etc. (see text). Salt marsh beyond. 
complex. Astraeus stellatus is common. Thelephora terrestris is found growing 
about the stems of Hudsonia tomentosa. The puffball, Lycoperdon T' urnert, 
was found associated with these, while C/itocyde trullisata, found with largely 
developed base and small pileus, indicates, according to Prof. PECK, who 
identified it, something unusual in the conditions of growth. Aethalium sep- 
ficum, a myxomycete, is found commonly attached to decaying driftwood. 
Dune Marsh Formation. The dune-marsh formation is typically developed 
at Sea Side Park, and to a less extent at Ocean City. The plants which form 
it inhabit the depressions of the dunes, which reach to water level. The 
species, therefore, associated together are essentially of a marsh habit. The 
dune marshes at Sea Side Park are somewhat different in character in different
