Coastal Plain Beaksedge Depression


Element Identifiers

NVCS association: Rhynchospora (careyana, inundata) Seasonally Flooded Herbaceous Vegetation

Database Code: CEGL004132

Formation: Seasonally flooded temperate or subpolar grassland

Alliance: RHYNCHOSPORA (CAREYANA, INUNDATA) SEASONALLY FLOODED HERBACEOUS ALLIANCE (V.A.5.N.k.22)

Element Concept

Summary: These are seasonally flooded upland depressions dominated by Rhynchospora inundata and/or Rhynchospora careyana. This broadly defined type represents vegetation dominated by the nominal species for the states given. Additional types may be developed as more information becomes available. Some additional species that may be present in stands of this type include Panicum hemitomon, Panicum verrucosum, Rhynchospora cephalantha, Rhynchospora filifolia, Andropogon capillipes, Xyris fimbriata, Xyris sp., Lachnanthes caroliana, Fuirena sp., Lycopodiella appressa, Eupatorium leptophyllum, Pontederia cordata, Solidago latissimifolia, and Triadenum virginicum. Floating aquatic plants such as Nymphaea odorata and Nymphoides aquatica may be present. The low cover of woody plants may be provided by Hypericum brachyphyllum and seedlings of Pinus elliottii.

Environment: See Summary

Vegetation: A stand assigned here from the Ocala National Forest (Florida) is dominated by Rhynchospora inundata, with Panicum hemitomon, Rhynchospora filifolia, Xyris fimbriata, Xyris sp., Lachnanthes caroliana, Fuirena sp., Lycopodiella appressa, Panicum verrucosum, Rhynchospora cephalantha, Andropogon capillipes, Eupatorium leptophyllum, Pontederia cordata, Solidago latissimifolia, and Triadenum virginicum. Floating aquatic plants such as Nymphaea odorata and Nymphoides aquatica may be present. The low cover of woody plants may be provided by Hypericum brachyphyllum and seedlings of Pinus elliottii.

Herbaceous Seepage Bogs


Apalachicola Seepage Bog


Element Identifiers

NVCS association: Andropogon arctatus - Rhynchospora chapmanii Herbaceous Vegetation

Database Code: CEGL008596

Formation: Saturated temperate or subpolar grassland

Alliance: RHYNCHOSPORA OLIGANTHA - SARRACENIA SPP. - (ARISTIDA BEYRICHIANA, CTENIUM AROMATICUM) - OSMUNDA CINNAMOMEA / SPHAGNUM SPP. SATURATED HERBACEOUS ALLIANCE (V.A.5.N.m.17)

Element Concept

Summary: This seepage slope or bog is found in northern Florida on the Apalachicola National Forest and may occur elsewhere in the region. It is floristically and ecologically related to wetland savannas of the region but is presumed to be more heavily influenced by seepage flow. Herbaceous dominants are Aristida beyrichiana, Andropogon arctatus, Dichanthelium leucothrix, and Ctenium aromaticum. A scattered shrub layer may be present which includes Hypericum spp. and Ilex glabra, among other species, the density of which is dependent upon fire history.

Environment: More information is needed.

Vegetation: Herbaceous dominants are Aristida beyrichiana, Andropogon arctatus, Dichanthelium leucothrix, and Ctenium aromaticum. This community supports a diverse mixture of wetland species. Species with high cover values in a single plot include Andropogon tracyi, Eurybia eryngiifolia (= Aster eryngiifolius), Bigelowia nudata, Dichanthelium strigosum var. leucoblepharis, Erigeron vernus, Eriocaulon decangulare, Hypericum cistifolium, Hypericum microsepalum, Lachnocaulon anceps, Lobelia glandulosa, Lophiola aurea (= Lophiola americana), Panicum rigidulum var. pubescens, Triantha racemosa (= Tofieldia racemosa), Polygala cruciata, Rhynchospora plumosa, Rhexia alifanus, Rhexia petiolata, and Xyris ambigua (S. Carr unpubl. data).
