Heterotheca (common names goldenasters, camphorweed, and telegraph weed) is a genus of North American plants in the family Asteraceae.
==Etymology== Heterotheca (heterothe'ca:) comes from Ancient Greek "other, different" and "case, chest" (botanically, "ovary") and refers to the difference in shape, in some species in the genus, between the cypselae (achenes containing seed) of the disk and ray florets. ==Description, biology== These are annual and perennial herbs bearing daisy-like flower heads with yellow disc florets and usually yellow ray florets, associated with mesic to xeric habitats across North America. Several species now included in Heterotheca were previously classified in the genus Chrysopsis.
