Coreopsideae is a tribe of flowering plants belonging to the Asteroideae subfamily.[1]
Classification
This tribe includes genera like Cosmos and Dahlia.[2]
A similar group has been recognized since 1829, generally as part of the tribe Heliantheae (Cassini, 1819).[3] In the late 20th century, molecular studies caused a slightly redefined version of this group to be recognized as its own tribe, Coreopsideae.[3] The larger version of Heliantheae was split into tribes including Bahieae, Chaenactideae, Coreopsideae, Helenieae and, finally, Heliantheae (sensu stricto).[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]
