This is a floating marsh of the Mississippi Deltaic Plain occurring on extensive floating peat mats. Morella cerifera (= Myrica cerifera var. cerifera) dominates and may be the only species present other than Panicum hemitomon. |

The open to scattered canopy consists of <i>Pinus palustris</i>. A sparse scrub oak layer consists of <i>Quercus laevis</i>. The shrub layer is diverse and includes the juxtaposition of species normally widely separated ecologically by moisture, from pocosin species to xeric sandhill species. Dominant shrubs include <i>Leiophyllum buxifolium, Cyrilla racemiflora, Clethra alnifolia, Vaccinium tenellum</i>, and <i>Gaylussacia dumosa (= var. dumosa)</i>. Other shrubs include <i>Hypericum lloydii, Vaccinium crassifolium ssp. sempervirens (= Vaccinium sempervirens), Kalmia latifolia, Lyonia mariana</i>, and <i>Gaylussacia frondosa (= var. frondosa)</i>. Herbs are few and include <i>Liatris</i> sp. and <i>Schizachyrium scoparium</i>. This community occurs on sandstone outcrops and gravel beds on exposed ridge situations in a landscape of longleaf pine sandhills. Occurrences of this community are small and are limited to rare and localized edaphic situations, where sandstone, gravel, and kaolinite outcrops provide subirrigation, augmenting the water supply. In this respect, this community shows a conceptual similarity to the ~<i>Pinus palustris / Quercus marilandica / Vaccinium crassifolium / Aristida stricta</i> Woodland (CEGL003599)$$ but differs consistently in floristic composition (for instance in lacking three of the four nominal species). |

Schizachyrium scoparium - Sporobolus compositus - Fimbristylis puberula var. puberula Wooded Herbaceous Vegetation

This dry blackland prairie community of the Upper West Gulf Coastal Plain of Arkansas typically occurs on dry ridges. Examples also occur on recovering eroded areas. The vegetation is typically short (2-3 feet) and somewhat sparse, with patches of bare ground present. Dominant species include <i>Schizachyrium scoparium, Sporobolus compositus (= Sporobolus asper)</i>, and <i>Fimbristylis puberula var. puberula</i>. Other herbaceous species include <i>Acacia angustissima, Agalinis skinneriana, Andropogon virginicus, Asclepias viridiflora, Asclepias viridis, Manfreda virginica</i> (rarely), <i>Coreopsis lanceolata, Croton capitatus, Croton monanthogynus, Dalea purpurea, Delphinium carolinianum ssp. virescens, Hedyotis nigricans var. nigricans, Liatris squarrosa, Rudbeckia hirta</i> (in places large clones covering 2-3 square m perhaps the result of heavy grazing in the past), and <i>Ruellia humilis</i>. The bare soil is often covered with blue-green algae (<i>Nostoc</i> sp.). Occasional woody species include <i>Sideroxylon lanuginosum (= Bumelia lanuginosa), Diospyros virginiana, Fraxinus americana, Quercus muehlenbergii</i>, and <i>Juniperus virginiana var. virginiana</i> which occur locally during periods of fire suppression or between severe droughts. Fire and edaphic factors (drought) play a role in limiting woody vegetation distribution in this community. Soils are calcareous alkaline clays with the high shrink-swell character of the Sumter and Demopolis series over deep calcareous substrates comprising marl, chalk, or broken limestone. |
