CEGL003954 Hypericum tenuifolium / Aristida stricta Wet Dwarf-shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Atlantic St. John''s-wort / Pineland Three-awn Wet Dwarf-shrubland
Colloquial Name: Wet Pine Flatwoods (Depression Type)
Hierarchy Level: Association
Type Concept: This association represents very small-scale and localized depressions or swales in extremely xeric sandhills in southeastern North Carolina. Hypericum tenuifolium dominates the shrub layer, while other scattered shrubs such as Lyonia mariana and Gaylussacia dumosa may be present. Aristida stricta and Andropogon spp. are the dominant herbs. In this landscape, Aristida stricta is restricted to this community, apparently because of the extremely xeric conditions of the surrounding sandhill community [see ~Pinus palustris / Quercus laevis - Quercus geminata / Rhynchospora megalocarpa Woodland (CEGL003590)$$].
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Apparently described from the Highway 421 sandridge north of Wilmington, NC. It is not clear if this type occurs anywhere else (M. Schafale pers. comm.). It is uncertain how to interpret this community. Its dynamics and classification are uncertain, but it forms striking openings in the longleaf landscape.

Physiognomy and Structure: No Data Available
Floristics: Hypericum tenuifolium (= Hypericum reductum) dominates the shrub layer, while other scattered shrubs such as Lyonia mariana and Gaylussacia dumosa (= var. dumosa) may be present. Aristida stricta and Andropogon spp. are the dominant herbs. In this landscape, Aristida stricta is restricted to this community.
Dynamics: All known sites are less than ΒΌ acre in size and embedded in a matrix of pyrogenic Pinus palustris vegetation. These small patches almost certainly burned along with the surrounding matrix (M. Schafale pers. comm.).
Environmental Description: This type occurs in rounded, low depressions or swales in the Outer Coastal Plain Sandhills of North Carolina. These areas do not appear to retain water from precipitation events, but have a high water table at or near the surface although the water table is not so high as to eliminate the Aristida stricta (which does not tolerate flooding). Limestone underlies much of the area, but the sand is deep enough to reduce the influence of the limestone (M. Schafale pers. comm.).
Geographic Range: This association is endemic to the Outer Coastal Plain of southeastern North Carolina.
