Another common name for this plant is Lance-leaved Coreopsis, even though the leaves are usually more broad toward their tips than near their bases. Sand Coreopsis (Coreopsis lanceolata) can be distinguished from other Coreopsis spp. primarily by the lack of lobes on its basal leaves and some of its opposite leaves. Different populations of Sand Coreopsis can vary significantly in the hairiness of the stems and leaves, ranging from glabrous (var. lanceolata) to conspicuously hairy (var. villosa). It has been suggested that the hairy variety may be the result of a naturally occurring hybrid of Coreopsis lanceolata with Coreopsis pubescens, or that it should be considered a distinct species (see Flora of North America, Vol. 21, at
