This community occurs on vernally moist (seasonally saturated), open, rocky slopes on Glen Rose Limestone, on the Edwards Plateau of central Texas. Common and characteristic species include <i>Muhlenbergia reverchonii, Bouteloua hirsuta var. pectinata (= Bouteloua pectinata)</i>, and <i>Carex microdonta</i>. The abundance of <i>Muhlenbergia reverchonii</i> may reflect an augmentation resulting from past grazing.

This association occupies interdune ponds in quartz sand dunes, with seasonal flooding, located in the Chihuahuan Desert of Texas. Following flooding soils remain relatively saturated. <i>Salix exigua</i> is the only tree and forms an open to locally closed canopy 4-10 m high. <i>Baccharis neglecta</i> and <i>Baccharis salicifolia</i> form a usually dense shrub layer. Herbs include <i>Schoenoplectus maritimus (= Scirpus maritimus), Schoenoplectus tabernaemontani (= Scirpus tabernaemontani), Eustoma exaltatum, Pluchea odorata var. odorata, Xanthium strumarium</i>, and the rare species <i>Cyperus onerosus</i>. Drier interdune depressions have ~<i>Baccharis salicifolia - Baccharis neglecta / Eustoma exaltatum</i> Shrubland (CEGL004590)$$. |

This community occurs on rocky cliffs and very steep slopes over limestone in northwestern Texas. <i>Cercocarpus montanus var. paucidentatus</i> is dominant. <i>Ceanothus greggii</i> is often common. The dwarf-shrub <i>Petrophyton caespitosum</i> is nominal as an indicator of exposed bedrock, and varies from scattered to very abundant. Other rock outcrop herbs and shrubs occurs. |

This community occurs on limestone rimrock along mesic canyons in the southern portion of the Edwards Plateau of central Texas. It occurs on the Edwards Limestone, and geologically similar limestone formations (such as the Devils River and Segovia formations), and less commonly on the Glen Rose formation. Normally, it occurs as a lengthy but relatively narrow band (5-10 m wide) along the flat upper surface of the rimrock, and extends onto sloping to vertical limestone exposures, with shrubs and herbs rooted in fissures and crevices in the rock. Dominant shrubs are <i>Buddleja racemosa, Ungnadia speciosa</i>, and <i>Toxicodendron radicans ssp. eximium</i>. Other characteristic woody components (many of then endemic to the Edwards Plateau or with restricted distributions) are <i>Ageratina havanensis (= Eupatorium havanense), Eysenhardtia texana, Morus microphylla, Quercus sinuata var. breviloba, Rhus virens var. virens</i>, and <i>Toxicodendron pubescens</i>. A rare shrub restricted to this community is <i>Philadelphus ernestii</i>. Other woody plants can include <i>Callicarpa americana, Celtis laevigata var. laevigata, Celtis laevigata var. reticulata, Cornus drummondii, Croton fruticulosus, Diospyros texana, Fraxinus texensis, Carya ovata, Ilex decidua, Juniperus ashei, Nolina lindheimeriana, Nolina texana, Opuntia leptocaulis, Opuntia engelmannii var. lindheimeri, Parthenocissus quinquefolia, Prunus mexicana, Prunus serotina var. eximia, Ptelea trifoliata ssp. angustifolia var. persicifolia, Quercus buckleyi, Quercus fusiformis, Rhus trilobata var. trilobata, Sideroxylon lanuginosum ssp. rigidum, Smilax bona-nox, Ulmus crassifolia, Viburnum rufidulum</i>, and <i>Yucca rupicola</i>. Characteristic herb species of this community are <i>Acalypha phleoides (= Acalypha lindheimeri), Aquilegia canadensis, Argyrochosma dealbata (= Notholaena dealbata), Aristolochia serpentaria, Asplenium resiliens, Brickellia cylindracea, Chamaesyce villifera, Cheilanthes alabamensis, Cheilanthes horridula, Desmodium psilophyllum, Euphorbia cyathophora, Lespedeza texana, Linum rupestre, Mentzelia oligosperma, Mirabilis albida (= Mirabilis dumetorum), Oxalis dillenii, Pellaea atropurpurea, Pellaea ovata, Perityle lindheimeri var. lindheimeri, Polygala lindheimeri, Phyllanthus polygonoides</i>, and <i>Salvia roemeriana</i>. Upslope, this shrubland adjoins <i>Juniperus ashei</i> woodlands or <i>Quercus fusiformis</i> woodlands. Downslope (in the canyons), it adjoins mesic deciduous or mixed deciduous-evergreen oak forests and woodlands. |

This is a mesic forest described from the northern parts of the Upper East Gulf Coastal Plain, ranging from Kentucky south to Tennessee and possibly northern Alabama. Its full range is not known. Stands are found on lower toeslopes above cypress or bottomland hardwood forests. It was initially described from Kentucky (Marshall, McCracken, and Carlisle counties). Typical canopy trees include <i>Quercus phellos, Quercus michauxii, Quercus pagoda, Quercus falcata</i>, and <i>Quercus stellata</i>. These are often mixed with swamp species like <i>Quercus palustris</i> and upland forest species like <i>Quercus alba</i>. Flooding occurs in winter, and groundwater probably remains high through most years, but upper soil horizons may become relatively dry in the summer. Forests upslope are dominated by <i>Quercus alba</i> and <i>Quercus falcata</i>. More information is needed on this vegetation across its range. |
