Discussion

In the flora area, Schenkia spicata is established only on the island of Nantucket, records from which span more than 150 years. It was formerly known from Maryland and Virginia.

Taxa sometimes treated as varieties or subspecies of Schenkia spicata (as Centaurium) were treated as dis­tinct species of Schenkia by G. Mansion (2004), whose treatment is followed here, and by some earlier authors. The plants in the flora area are S. spicata in the narrow sense.
