Name: Fuirena scirpoidea - Fuirena longa - Rhynchospora microcarpa - Rhynchospora divergens Herbaceous Vegetation
Reference: Southeastern Ecology Working Gro...
Description: This association occupies natural freshwater pothole ponds and interdunal swales in neutral to moderately alkaline sands of Pleistocene and Holocene barrier islands in the Gulf Coastal Bend of southern Texas. The vegetation is dominated by <i>Rhynchospora</i> spp., <i>Fuirena</i> spp., <i>Eleocharis</i> spp., and <i>Cyperus</i> spp. In addition to <i>Fuirena scirpoidea, Fuirena longa, Rhynchospora microcarpa</i>, and <i>Rhynchospora divergens</i>, other characteristic and common species include <i>Rhynchospora nitens, Cyperus oxylepis, Cyperus polystachyos var. texensis, Eleocharis geniculata (= Eleocharis caribaea), Eleocharis flavescens, Eleocharis montevidensis, Eleocharis parvula, Xyris jupicai, Agalinis fasciculata, Bacopa monnieri, Buchnera americana (= Buchnera floridana), Oldenlandia uniflora (= Hedyotis uniflora var. fasciculata), Spiranthes vernalis, Drosera brevifolia</i>, and <i>Utricularia subulata</i>. This association occupies sandy depressions, with variable hydrology. Following heavy rains, these ponds can be inundated for several weeks, but desiccate and draw down in drier periods. Structure and composition vary with depth of water (or depth to water table) and frequency of inundation, ranging from sparse cover of tufted annuals to complete coverage by rhizomatous perennials. Long-term drying due to natural succession or anthropogenic drainage can result in upland grassland types dominated by <i>Andropogon virginicus</i> and/or <i>Schizachyrium scoparium</i>. This association often occurs in a matrix of ~<i>Quercus fusiformis - Persea borbonia</i> Forest (CEGL002117)$$ in ~<i>Quercus fusiformis - Prosopis glandulosa</i> Forest Alliance (A3190)$$.
