Ecology
Habitat
In the Coastal Plain in Florida, S. smallii has been found in oak-hickory woodlands; loamy soil of steep, shaded ravines; a shell mound within an otherwise low floodplain; deciduous woodlands; mixed pine-hardwood forests; and rich calcareous slopes (FSU Herbarium). Associated species include Arisaema, Conopholis, Toxicodendron, Diospyros virginiana, Berchemia, Carya, Sabal palmetto, Aesculus pavia, Amorpha fruticosa, Fagus, Magnolia, and Quercus (FSU Herbarium). Substrate types include loam, sandy humus, loamy soil, and shell mounds (FSU Herbarium).
