Coreopsideae is a tribe of flowering plants belonging to the Asteroideae subfamily. [1] It includes widely cultivated genera such as Cosmos and Dahlia .

Contents

A similar group has been recognized since 1829, generally as part of the tribe Heliantheae (Cassini, 1819). [2] In the late 20th century, molecular studies caused a slightly redefined version of this group to be recognized as its own tribe, Coreopsideae. [2] The larger version of Heliantheae was split into tribes including Bahieae, Chaenactideae, Coreopsideae, Helenieae and, finally, Heliantheae (sensu stricto). [3] Within the tribe, the traditional definition of genera based on flower and fruit characters does not reflect evolutionary relationships as inferred through molecular phylogenetics. [4]

The tribe is characterized by shiny green bracts at the base of the flower head in two rows: an inner row of tightly spaced bracts and an outer row of a smaller number pointing downward. [5] It includes five genera that use C4 carbon fixation: Chrysanthellum , Eryngiophyllum , Glossocardia (including Guerreroia), Isostigma , and Neuractis . These genera are thought to share a common ancestor and thus a single origin of C4 carbon fixation. [6]

The family Asteraceae, with the original name Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown.

Senecioneae is the largest tribe of the Asteraceae, or the sunflower family, comprising over 150 genera and over 3,500 species. Almost one-third of the species in this tribe are placed in the genus Senecio. Its members exhibit probably the widest possible range of form to be found in the entire plant kingdom, and include annuals, minute creeping alpines, herbaceous and evergreen perennials, shrubs, climbers, succulents, trees, and semi-aquatic plants.

Common characters are the deeply incised corollas of the disc florets, with five lobes, sometimes merged in two lips, flower heads with overlapping involucral bracts, anthers with tails and pointy tips, the styles usually stick far out of the florets and are essentially hairless. Most species are herbs, but some are vines, shrubs, or small trees.

Some species are known by the common name bushsunflower.
