Heterotheca, (common names golden asters, false goldenasters, camphorweed, or telegraph weed)[3] are North American plants in the sunflower family.[2][4]

These are annual and perennial herbs bearing daisy-like flower heads with yellow disc florets and usually yellow ray florets. Several species now included in Heterotheca were previously classified in the genus Chrysopsis[1][3]

Heterotheca species are often used as food plants by the larvae of some Lepidoptera species including Schinia lynx, Schinia nubila and Schinia saturata (all of which have been recorded on Heterotheca subaxillaris).
