Additional Information at NatureServe

Diagnostic Characteristics:
Characters that distinguish Heterotheca from other genera in the Aster family are the leaves alternately arranged, capillary bristles making up the pappus are double (in two distinct lengths). 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.

While this species responds well to disturbance, care should be taken to protect the population from disturbance that would cause erostion or weed invasion at the site.
