Moist, seepy spots are often dominated by species such as Rhynchospora colorata, Ludwigia microcarpa, and Rhynchospora thornei. Numerous species (most of them newly discovered and described) are endemic to this community, including Onosmodium decipiens, Erigeron strigosus var. dolomiticola, Silphium glutinosum, Castilleja kraliana, Coreopsis grandiflora var. inclinata, Dalea cahaba, Spigelia alabamensis, and Solanum pumilum. The moss Pleurochaete luteola may be present in patches at the margins. The scattered woody species include Pinus palustris, Pinus virginiana, Cercis canadensis, Cornus florida, Chionanthus virginicus, Rhus aromatica, Pinus taeda, Forestiera ligustrina, Juniperus virginiana var. virginiana, Toxicodendron pubescens, Sabal minor, and Smilax bona-nox.

Environmental Description: This community is found on thin soil dolostone glades over Ketona Formation dolomitic limestone in Bibb County, Alabama, near the southern terminus of the Ridge and Valley physiographic province.
Geographic Range: This community is a very distinctive type limited to outcrops of Ketona Dolomite in Bibb County, Alabama, near the southern terminus of the Ridge and Valley physiographic province. It harbors numerous endemic species (endemic to this community type), as well as unique combinations of species with various biogeographic affinities, including the Southeastern Coastal Plain and Ridge and Valley. There is no likelihood of this community''s range being extended through further survey.
