Vernonieae is a tribe of about 1300 species of plants in the aster family. They are mostly found in the tropics and warmer temperate areas, both in the Americas and the Old World. They are mostly herbaceous plants or shrubs, although there is at least one tree species, "Vernonia arborea".

Taxonomy

Vernonieae is considered sister to the tribe Liabeae.cite journal | journal = Molecular Phylogenetics and Evolution | volume = 44 | issue = 1 | date = July 2007 | pages = 89–103 | doi = 10.1016/j.ympev.2006.12.024 | title = A phylogeny of the “evil tribe” (Vernonieae: Compositae) reveals Old/New World long distance dispersal: Support from separate and combined congruent datasets (trnL-F, ndhF, ITS) | author = Sterling C.

In many works some 80% of the species in this tribe are classified in the genus "Vernonia". Other authors, like Harold E. Robinson, divide the tribe into a larger number of small genera.
