Description: This alliance consists of sandy or rocky areas dominated by ~Hudsonia tomentosa$. This alliance is largely confined to maritime interdunes. This alliance occurs on well-drained sands of back dunes and interdunes, and is documented from Assateague Island; it is a maritime dwarf-shrubland characterized by ~Hudsonia tomentosa$, a species adapted to sand burial. ~Hudsonia tomentosa$ is dominant, occurring as discrete patches that may coalesce into a dense mat on older, more stabilized dunes. A number of other shrubs, such as ~Morella pensylvanica (= Myrica pensylvanica), Morella cerifera (= Myrica cerifera), Pinus taeda$ saplings, and ~Prunus maritima$, may occur but are low in abundance and cover. ~Morella pensylvanica$ shrubs and ~Pinus taeda$ saplings are almost non-existent but can occur as scattered individuals. Herbaceous vegetation is also quite sparse (less than 5% cover) but may include scattered individuals of ~Panicum amarum var. amarulum, Panicum amarum var. amarum, Solidago sempervirens, Nuttallanthus canadensis, Lechea maritima, Ammophila breviligulata, Pseudognaphalium obtusifolium (= Gnaphalium obtusifolium), Schizachyrium littorale (= Schizachyrium scoparium ssp. littorale), Dichanthelium acuminatum, Oenothera humifusa, Cyperus grayi, Artemisia stelleriana, Chamaesyce polygonifolia$, and ~Diodia teres$. ~Toxicodendron radicans$ is a common vine. Scattered vines of ~Smilax rotundifolia$ and canes of ~Rubus argutus$ are occasional. The unstable substrate is influenced by wind-deposited sand and supports no soil development; large patches of sparsely vegetated or unvegetated sand are common.
