Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.
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.
Harold Ernest Robinson was an American botanist and entomologist.
Jacobaea is a genus of flowering plants in the tribe Senecioneae and the family Asteraceae. Its members used to be placed in the genus Senecio, but have been separated into the segregate genus Jacobaea on the basis of molecular phylogenetics in order to maintain genera that are monophyletic.
Aequatorium is a genus of flowering plants in the aster family. It was described as a genus in 1978. It is a member of the tribe Senecioneae and native to South America.
Dendrophorbium is a genus of South American flowering plants in the family Asteraceae.
Pentacalia millei is a species of flowering plant in the family Asteraceae. It is found in Ecuador and Peru. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude grassland. It is threatened by habitat loss.

Lomanthus fosbergii, synonym Talamancalia fosbergii, is a species of flowering plant in the family Asteraceae endemic to Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. It was first described by José Cuatrecasas in 1953 as Senecio fosbergii. The genus Lomanthus is placed in the tribe Senecioneae.

Pieter B. Pelser is a lecturer in Plant Systematics and the curator of the herbarium at the University of Canterbury in Christchurch, New Zealand. One research interest is the evolutionary history of the tribe Senecioneae, one of the largest tribes in the largest family of flowering plants. He wrote the most recent attempt to define and delimit this tribe and its problematic founding species Senecio. He also studies insects that eat these plants (Longitarsus) which contain pyrrolizidine alkaloids and what makes them choose which plants they eat.
Chersodoma is a genus of South American flowering plants in the daisy family. Members of this genus or dioecious shrubs or subshrubs.
Lasiocephalus is a genus of South American flowering plants in groundsel tribe within the sunflower family. The genus was shown to be part of Senecio and predominantly occurs in tropical alpine-like regions.
Heterosperma is a genus of flowering plants in the sunflower family, native to North and South America.
Microliabum is a genus of South American flowering plants in the family Asteraceae.
