Coreopsis lanceolata
Coreopsis pubescens
Plants that have been called Coreopsis lanceolata var. villosa Michaux often have 5+ aerial internodes 6+ cm long proximal to the first peduncle; they may merit recognition as a distinct taxon or may be hybrids (or derivatives) from crosses between C. lanceolata and C. pubescens.

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.
