Marshallia angustifolia (Michaux) Pursh. Gulf Coast Barbara's-buttons. Phen: Late Jun-Sep. Hab: Pine savannas, seepage bogs. Dist: E. GA south to c. peninsular FL, west to e. TX; historically disjunct on (likely) the eastern Highland Rim (where mapped here) or Cumberland Plateau of e. TN (Michaux's type came from TN).

Origin/Endemic status: Endemic

Taxonomy Comments: We disagree with Channell's dismissal of the TN record by Michaux as a mislabeling and his identification of the Michaux specimen as representing M. graminifolia of the Atlantic Coastal Plain.
