Name: Pallavicinia lyellii - Sphagnum sp. Nonvascular Vegetation
Reference: Southeastern Ecology Working Gro...
Description: This vegetation is found where seepage occurs through acidic clays on saturated, vertical to near-vertical, shaded exposures along large creeks in the Coastal Plain. Related vegetation is reported from Weches/Recklaw geology (which may have calcareous tendencies) in Texas and from the Ouachita Mountain Region of Arkansas. The wetter phase of this vegetation is dominated by <i>Pallavicinia lyellii, Atrichum</i> sp., <i>Plagiomnium</i> sp., <i>Sphagnum</i> sp., and other unidentified liverworts and mosses. An often evident zonation has the <i>Sphagnum</i> more prevalent near to the exposed top of the bank, and the <i>Pallavicinia</i> occupying the lower, more heavily shaded portion. Herbaceous vascular plants are scattered but not dominant; they include <i>Symphyotrichum lateriflorum (= Aster lateriflorus), Poa autumnalis, Mitchella repens, Viola x primulifolia, Osmunda cinnamomea</i>, and <i>Woodwardia areolata</i>. This vegetation occurs on cutbanks of large creeks. Shrubs often arch over the banks from above, shading them for much of the day. Individual occurrences may continue along several hundred m of stream length on banks which are about 5 m high. The adjacent drier phase may occur on banks which receive greater insolation, or where the soils are of coarser texture. These areas are dominated almost entirely by the same <i>Sphagnum</i> sp. which forms a component of the wetter phase. Related vegetation reported from Weches/Recklaw geology of Texasmay actually represent a distinct association.
