CEGL004974 (Pinus elliottii) / Cyrilla racemiflora - Persea palustris - Magnolia virginiana - Smilax laurifolia Wet Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: (Slash Pine) / Swamp Titi - Swamp Bay - Sweetbay - Laurel Greenbrier Wet Shrubland

Colloquial Name: East Gulf Seepage Pocosin

Hierarchy Level:  Association

Type Concept: This East Gulf Coastal Plain pocosin is known only from seepage-fed areas of sapric muck soils at the base of a 10-m high bluff in the vicinity of Grand Bay savanna. It occurs on a low Pleistocene coastal terrace, adjacent to the more elevated Oligocene surface. The vegetation is dominated by Cyrilla racemiflora, Persea palustris, Magnolia virginiana, and Smilax laurifolia. Stands have a low and relatively stunted stature, achieving heights of only 3-4 m (10-12 feet). Emergent Pinus elliottii var. elliottii and/or Taxodium ascendens may be present. A similar species combination inhabits the more widespread East Gulf Coastal Plain streamhead shrubland type ~Ilex coriacea - Lyonia lucida - Smilax laurifolia Wet Shrubland (CEGL004666)$$, but this topographic situation is very different.

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Pinus elliottii in the name of this type serves to distinguish it from ~Cyrilla racemiflora - Persea palustris - Magnolia virginiana Wet Shrubland (CEGL004449)$$, to which it is very close to in name. The latter association is restricted to the shores of Carolina bay lakes in North Carolina. Additional floristic information would be useful. A similar species combination inhabits the more widespread East Gulf Coastal Plain streamhead shrubland type, ~Ilex coriacea - Lyonia lucida - Smilax laurifolia Wet Shrubland (CEGL004666)$$, but this topographic situation is very different.
