Diagnostic Characteristics:
This is the only member of the genus in Kentucky. Characters that distinguish Heterotheca from other genera in the Aster family are the capillary bristles making up the pappus are double (bracts around the achene come in two distinct lengths). The achenes of the rays lack bristles. The involucral bracts (bracts around the flowering head) are imbricate (overlapping). The flowering heads as a whole are radiate, ca 1 cm across, and the rays (the outside flowers) are yellow. The leaves are alternately arranged.
