This community occurs on more stable and vegetated gypsum dunes of Trans-Pecos Texas and possibly adjacent areas. Artemisia filifolia, Psorothamnus scoparius, Atriplex canescens, and Dalea lanata share dominance in the shrub stratum, with Yucca elata and Chrysothamnus pulchellus also present. Herbaceous species present are Sporobolus giganteus, Achnatherum hymenoides (= Oryzopsis hymenoides), Andropogon hallii, Gaillardia multiceps, and Bouteloua breviseta. This community occurs in association with the Artemisia filifolia / Andropogon hallii - Achnatherum hymenoides Gypsum Dune Shrubland (CEGL004559). |

This alliance contains woodlands occurring on calcareous or circumneutral talus comprised of large boulders, or on rock outcrops. These woodlands often occur in association with rich forests, those of the ~~Acer saccharum - Fraxinus americana - Tilia americana$ Forest Alliance (A.217)$$. As opposed to the forest alliance, communities of woodland alliance have an open canopy and as such support more light-demanding species than are found in the understory of rich forests. Associated canopy species include ~Acer saccharum, Quercus rubra$. The shrub layer is usually sparse. Herbs of this alliance include ~Adlumia fungosa, Clematis occidentalis, Geranium robertianum, Cystopteris bulbifera, Carex umbellata$, and ~Antennaria plantaginifolia$. This alliance occurs in southern Canada, lower New England, the northern Appalachians, and south to mountains of West Virginia and Virginia. In Maryland, this alliance is found along the Potomac River (Garrett County). |

This stringer woodland association is characterized by <i>Taxodium ascendens</i> and <i>Nyssa biflora</i> with a mixed sedge understory. These stringers occur in seasonally (or semipermanently) flooded flow-ways that include swales, limesinks and other depressional wetlands. The sedges <i>Carex striata, Rhynchospora cephalantha</i>, and <i>Rhynchospora careyana</i> tend to form a thick mat in the soggy substrate. Evergreen shrubs, such as <i>Lyonia lucida, Clethra alnifolia</i>, and <i>Cyrilla racemiflora</i>, will often be found growing in raised patches or around the bases of large trees. Periodic droughts allow for the occasional establishment of <i>Acer rubrum</i>, although it is less likely to persist over time given a relatively frequent fire regime. This regime will maintain the open herbaceous layer and remove other hardwood invaders as well. |

Podostemum ceratophyllum Permanently Flooded Herbaceous Alliance

Vegetation of shoals in rocky streambeds and riverbeds in mature drainage systems where the streams have cut down to rock, and the floodplain is relatively narrow; or on dams in moderately fast- to fast-flowing water. The vegetation grows attached to rocks in outcrops and stream rubble, or to dams in moderate- to fast-flowing water. This almost always is a monospecific community dominated by Podostemum ceratophyllum with no other vascular plants present; some Rhodophyta (red algae) may be present. |

This association represents montane grasslands occurring over 1220 m (4000 feet) elevation in the southern Appalachian Mountains dominated by <i>Carex pensylvanica</i>. Associated species include <i>Carex debilis, Polytrichum commune, Helenium autumnale, Danthonia compressa, Sibbaldiopsis tridentata, Fragaria virginiana, Ageratina altissima var. roanensis, Angelica triquinata, Oclemena acuminata (= Aster acuminatus), Bromus pubescens</i>, <i>Dennstaedtia punctilobula, </i>and <i>Rumex acetosella</i> (exotic). Woody species such as <i>Rhododendron catawbiense, Pieris floribunda, Rubus canadensis</i>, and <i>Robinia hispida</i>, may have sparse coverage in some occurrences. |
