Name:
Paspalum monostachyum - (Panicum amarum, Schizachyrium littorale) Herbaceous Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
This alliance includes the predominant grasslands of the South Texas Sand Sheet, the Ingleside barrier-strandplain in the Coastal Bend of Texas, as well as barrier islands and coastal situations of Texas and adjacent western Louisiana. These grasslands also occur on stabilized secondary dunes on barrier islands (Texas) or on beach dunes and relatively elevated backshore ridges above intertidal beaches on barrier islands and mainland areas (Louisiana). Common salt-spray-tolerant components may include Panicum amarum, Paspalum monostachyum, Schizachyrium littorale (= Schizachyrium scoparium ssp. littorale), Heteropogon contortus, Paspalum plicatulum, Paspalum vaginatum, Spartina patens, and Dichanthelium spp. Louisiana examples contain Oenothera drummondii, Strophostyles helvula, Solidago sempervirens, Croton punctatus, Hydrocotyle bonariensis, Sabatia arenicola, Ipomoea pes-caprae, Ipomoea imperati (= Ipomoea stolonifera), Gaillardia pulchella, Phyla nodiflora, Eleocharis albida, Juncus bufonius, Sisyrinchium biforme, Heterotheca subaxillaris, Astragalus nuttallianus, Pediomelum rhombifolium, Dalea emarginata, and others. Trichoneura elegans and Elionurus tripsacoides are present within their ranges in Texas. Minor changes in drainage can cause differences in species composition. Poorly drained areas may support inclusions of Spartina spartinae. On Texas barrier islands, these wetter inclusional grasslands contain Sporobolus spp., Eragrostis spp., Carex spp., Scirpus spp., Fuirena spp., and Fimbristylis spp. as important components and grade into grasslands of Uniola paniculata and Panicum amarum on drier, less stable dunes.
