Although estimates vary, the Sunflower Family (Asteraceae) is said to have somehwhere around 30,000 members or species. As a result of this large number of family members various categorization schemes have been devised to divide the family into groups, subfamilies, or tribes. One classification scheme includes the following tribes: Heliantheae (Sunflower Tribe), Madieae (Tarweed Tribe), Ambrosieae (Ragweed Tribe), Helenieae (Sneezeweed Tribe), Arctotideae (Gazania Tribe), Calenduleae (Marigold Tribe), Inuleae (Everlasting Tribe), Vernonieae (Ironweed Tribe), Eupatorieae (Eupatory Tribe), Anthemideae (Sagebrush Tribe), Senecioneae (Groundsel Tribe), Cynareae (Thistle Tribe), Mutisieae (Mutisia Tribe), Cichorieae (Chicory Tribe), and, of course, Astereae (Aster Tribe).
