Lachnanthes caroliniana (Lamarck) Dandy. Redroot. Phen: Jun-early Sep; Sep-Nov. Hab: Wet savannas, pocosin edges, shores of Coastal Plain depression ponds (and similar ponds in the mountains of Virginia), ditches, wet disturbed ground. Dist: The range is almost strictly on the Coastal Plain, and rather disjunct: s. NS, from MA to DE, from se. VA south to s. FL and west to e. LA (the Florida parishes), with inland disjunctions in w. VA, sc. TN (Coffee County), and w. LA (Vermilion Parish; Reid 2021); e. Cuba.

Origin/Endemic status: Native

Taxonomy Comments: The correct spelling of the specific epithet has been disputed; the original spelling was "caroliana," but Gandhi (1999) argues convincingly that this is a correctable typographic error.
