|discussion=<p>Subspecies rolfsii is nearly restricted to sandy substrates in peninsular Florida and southern Georgia and is most common on the central ridges of these states. It has been reported in error from Alabama, Mississippi, North Carolina, and Virginia. Plants of subspp. tuberosa and interior from sandy sites in southern South Carolina approach subsp. rolfsii and may be accommodated more properly here.</p>
