General Comments:
The entire state excepting the Florida Keys falls within the range of this plant, which extends from North Carolina to Texas. Herbarium specimens document occurrence, at least sporadically, throughout the peninsula but not in the Florida Keys. Counties without documented specimens are ones with heavy urbanization, dominance by unsuitable habitats, intensive farming or silviculture, or generally a lack of public access for botanizing.
