CEGL003867 Hypericum chapmanii - Ilex myrtifolia - (Nyssa ursina) Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Apalachicola St. John''s-wort - Myrtle Dahoon - (Bear Tupelo) Wet Shrubland
Colloquial Name: North Florida Apalachicola St. John''s-wort Wet Shrubland
Hierarchy Level: Association
Type Concept: This association represents open shrublands dominated by Hypericum chapmanii in northern Florida. Such areas may be found in a variety of habitats such as small flatwoods ponds and dome swamps or along the ecotones of larger ponds and domes in the region. The vegetation is typified by a moderate to dense shrub/dwarf-tree stratum 2-5 m tall, dominated by Hypericum chapmanii, typically with Ilex myrtifolia and Hypericum brachyphyllum present. A sparse emergent layer of Taxodium ascendens may be present. Other shrubs, such as Cyrilla parvifolia and/or Nyssa ursina, may also occur as codominants or significant components in some examples. Typical herbaceous species include Coreopsis nudata, Polygala cymosa, Lobelia floridana, and Pinguicula planifolia.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The growth form of Hypericum chapmanii is a dwarf-tree (single-trunked and up to 20 cm or more in diameter at base). Compare the related forest community dominated by Taxodium ascendens, Nyssa biflora, and Pinus elliottii var. elliottii, occurring in larger depression ponds in the same landscape. These are important breeding habitats for the Flatwoods Salamander (Ambystoma cingulatum).

Floristics: The vegetation is typified by a moderate to dense shrub/dwarf-tree stratum 2-5 m tall, dominated by Hypericum chapmanii, typically with Ilex myrtifolia and Hypericum brachyphyllum present.

Typical herbaceous species include Coreopsis nudata, Polygala cymosa, Lobelia floridana, and Pinguicula planifolia. A vegetation sample on the Apalachicola National Forest recorded the following species: Taxodium ascendens, Hypericum chapmanii, Hypericum brachyphyllum, Ilex myrtifolia, Eriocaulon decangulare, Eriocaulon compressum, Smilax laurifolia, Magnolia virginiana, Sarracenia flava, Oxypolis filiformis, and a number of Rhynchospora species (NatureServe Ecology unpubl. data). Examples from Eglin Air Force Base lack Nyssa ursina (C. Nordman pers. obs.).
