Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Swamp Tupelo - Riverflat Hawthorn - (Carolina Ash) / Mingled Beaksedge Wet Scrub

Colloquial Name: West Gulf Coastal Plain High Terrace Wooded Flatwoods Pond

Hierarchy Level:  Association

Type Concept: This community type occurs in isolated ponds in a longleaf pine landscape in the high Pleistocene terraces of central to western Louisiana and has been tentatively attributed to related sites in eastern Texas. A widely scattered supercanopy can be present; it may include Nyssa biflora or Pinus taeda. An open to fairly dense stratum of stunted trees or large tree-like shrubs may include Nyssa biflora, Crataegus opaca, Fraxinus caroliniana, Quercus laurifolia, Acer rubrum, Liquidambar styraciflua, and Magnolia virginiana. Smaller shrubs include Cephalanthus occidentalis, Morella cerifera, Ilex coriacea, Diospyros virginiana, Ilex amelanchier (rare but can be locally abundant), and Liquidambar styraciflua. The moderately dense to dense herb stratum is characterized by Amsonia tabernaemontana var. tabernaemontana, Aristida palustris, Carex glaucescens, Coelorachis rugosa, Dichanthelium sp., Eleocharis sp., Ludwigia pilosa, Panicum rigidulum var. pubescens, Panicum tenerum, Proserpinaca pectinata, Rhexia virginica, Rhynchospora corniculata, Rhynchospora mixta, Rhynchospora perplexa, Stylisma aquatica, Xyris laxifolia var. iridifolia.
