Discussion

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.).

(If the plant you're looking for doesn't show up in the auto-complete list, that means it either isn't described in Flora of North America yet, or it's listed under a synonym. And please note that Flora of North America is still missing several plant families, including Fabaceae, Apiaceae, Boraginaceae, and Polemoniaceae.)
