Name: Spartina patens - Panicum amarum - Hydrocotyle bonariensis Herbaceous Vegetation
Reference: Barbour, M. G., M. Rejmanek, A. ...
Description: This association occurs on low dunes of barrier islands along the Louisiana and Texas coasts. In Louisiana, it is known from the Chandeleurs and related islands, where <i>Spartina patens</i> replaces <i>Uniola paniculata</i> (which is present in small amounts) as the dominant grass along the upper beach and primary dune. Louisiana barrier islands are the only areas in the southeastern U.S. to show a dominance by <i>Spartina patens</i> on the upper beach and primary dune. On the barrier islands of coastal Texas, this vegetation is found on stabilized secondary dunes where <i>Spartina patens</i> and <i>Paspalum monostachyum</i> typically codominate. Other grasses that may be present include <i>Panicum amarum, Sporobolus virginicus, Cenchrus spinifex (= Cenchrus incertus), Eustachys petraea</i>, and <i>Eragrostis secundiflora ssp. oxylepis (= Eragrostis oxylepis)</i>. Other characteristic species include <i>Galactia canescens, Rhynchosia americana, Opuntia stricta, Chamaecrista fasciculata (= Cassia fasciculata), Lythrum californicum, Helianthus argophyllus, Croton punctatus, Fimbristylis castanea, Sabatia stellaris, Cakile</i> spp., <i>Chamaesyce bombensis (= Chamaesyce ingallsii)</i>, and <i>Ipomoea imperati (= Ipomoea stolonifera)</i>. The sediments which form beach parent material change abruptly between Ship Island (Mississippi) on the east and the Chandeleur Islands (Louisiana) to the west.
