Description:
This community occurs in seasonally flooded depression ponds developed by solution and collapse of carbonate rocks underlying acidic colluvial materials deposited on the eastern edge of the Great Valley of Virginia, in Augusta, Rockingham, and southern Page counties, Virginia. This community has a variable physiognomy, from an open woodland with scattered individuals or groves of <i>Quercus palustris</i>, to entirely herbaceous with a marginal zone of trees. <i>Quercus palustris</i> is the most common and characteristic tree species; other trees include <i>Acer rubrum, Nyssa sylvatica, Pinus rigida</i>, and <i>Diospyros virginiana</i>. The shrub (and woody vine) stratum is usually sparse or absent; it can include <i>Vaccinium corymbosum, Vaccinium fuscatum, Cephalanthus occidentalis</i>, and <i>Smilax rotundifolia</i>. The herb stratum is well-developed. Herbaceous species with high constancy include <i>Panicum rigidulum var. rigidulum, Panicum verrucosum, Eleocharis acicularis, Agrostis perennans, Dichanthelium acuminatum, </i><i>Hypericum boreale</i><i>, </i><i>Helenium virginicum</i> (endemic to this and related communities in Virginia and Missouri), <i>Panicum philadelphicum, Bidens frondosa, Viola lanceolata, Erechtites hieraciifolia, Symphyotrichum dumosum (= Aster dumosus), Fimbristylis autumnalis, Rhexia mariana</i>, and <i>Rhexia virginica</i>.
