Name: Panicum virgatum - Panicum rigidulum var. elongatum - Polygonum hydropiperoides Wet Meadow Reference: NatureServe Biotics 2019 Description: This association represents vegetation of sandbars of blackwater rivers of the Gulf Coastal Plain of Mississippi and possibly other states. These areas receive water during periods of rainfall, and become hot and dry during rainless intervals. Stands may be dominated by <i>Panicum virgatum, Panicum rigidulum var. elongatum</i>, and <i>Polygonum hydropiperoides</i>. In addition to these species, which were dominant in the examples seen, graminoids and forbs include <i>Eupatorium serotinum, Pluchea camphorata, Diodia teres, Solidago</i> sp. (cf. <i>Solidago canadensis), Aeschynomene</i> sp., <i>Rubus trivialis, Paspalum urvillei, Sida</i> sp., <i>Ipomoea</i> sp., <i>Hypericum galioides, Lycopus virginicus</i>, and <i>Mikania scandens</i>. A sparser and more open phase with lower <i>Panicum virgatum</i> cover contains <i>Verbena brasiliensis, Bulbostylis stenophylla, Croton capitatus, Houstonia</i> sp., <i>Agalinis fasciculata</i>, and <i>Dichanthelium</i> sp. Woody vines include <i>Smilax rotundifolia</i> and <i>Campsis radicans</i>. Scattered woody plants of low stature include <i>Salix nigra</i> and <i>Betula nigra</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:33690-{EFF8EFC3-C760-4D12-AD46-C98D7D1F4F7E} Plot-observations of this Community Concept: 0
