AuthorNuttall
DistributionGenerally throughout the state, with small gaps. Apparently least numerous in the Mountains and the Sandhills proper. First collected in 1891 in Randolph County. A specimen from Craven County is actually C. basalis.

Native of the Great Plains (apparently); now essentially throughout the U.S. and southern Canada.
AbundanceInfrequent to locally fairly common, except rare in the Mountains and Sandhills proper.
HabitatRoadsides, road fill, railroad margins, fields, pastures, airports, powerlines, disturbed soil.
PhenologyFlowering and fruiting late May-July.
IdentificationGolden Tickseed has showy yellow rays with deep red in the basal portion. Thus, it is similar to C. basalis, but the leaf segments are much narrower (none are elliptical). Also, the disk florets have only 4 lobes (vs. 5 lobes in C. basalis).
Taxonomic CommentsWe do not distinguish varieties here.

For excellent drawings of all species (except those recently described) and range maps (although now out-of-date), see the monograph by Smith (1976).
