Discussion
Bushy to wiry, nearly glabrous plants with leaf blades mostly simple, mostly oblanceolate, and 2–15+ mm wide and with relatively small heads, florets, and fruits from coastal Mississippi and included here in Coreopsis pubescens may merit recognition as C. debilis Sherff or C. pubescens var. debilis.
