|Natural range of Stylisma patens from USDA NRCS Plants Database.|
Common names: Coastal Plain dawnflower, Common dawnflower
Synonyms: Stylisma patens (Desrousseaux) Myint ssp. patens; Bonamia patens (Desrousseaux) Shinners var. patens; Stylisma patens (Desrousseaux) Myint var. patens; Bonamia aquatica (Walter) A. Gray
In the Coastal Plains, S. patens has been documented in a longleaf pine-mixed oak-wiregrass association on a sandy hill slope; frequently burned, mature longleaf pine-wiregrass community; sand of open pine/oak flatwoods; sandhills; edge of longleaf-slash pine/wiregrass community; oak scrub; high turkey oak sandhill; cyrpess depressions in flatwoods; sandy upland pine-oak forests; turkey oak-wiregrass community; upland pinewoods; and longleaf pine-oak barrens.  In disturbed habitats it has been found in boggy powerline corridors, moderately disturbed longleaf pine restoration sites, dry powerline corridors, sandy roadsides, turkey oak barren clearing, bulldozed scrub oak sandhills, and gravel pits. Soil types include sand and loamy sand.  Associated species include Liatris, Erianthus, Gymnopogon, Rhynchospora, Paronychia, and Dyschoriste. 
This species is thought to be dispersed by gravity.
