Discussion

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.

As here circumscribed, Coreopsis gladiata includes plants that others (without agreement among themselves) have treated as distinct species and/or varieties: C. falcata (leaves mostly basal and/or proximal, alternate, blades mostly lance-linear to linear, often 1–2 with 1–2 lateral lobes, faces not dotted; outer phyllaries lance-ovate to lance-linear; Ga., N.C., S.C.); C. floridana (leaves mostly basal and/or proximal, alternate, blades mostly lance-linear to linear, not lobed, not dotted; outer phyllaries broadly deltate-ovate; Fla.), C. helianthoides (leaves mostly cauline, alternate, blades mostly elliptic to lanceolate, not lobed, faces not dotted; outer phyllaries lance-ovate to lance-linear; Ala., Fla., Ga., La., Miss., N.C., S.C.), and C. linifolia (leaves basal and cauline or mostly cauline, alternate or opposite or both, blades mostly lance-linear to linear, seldom lobed, faces bearing dark or translucent dots; outer phyllaries lance-ovate to lance-linear; Ala., Fla., Ga., La., Miss., N.C., S.C., Tex., Va.).
