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 about 150 genera and 3,000 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 semiaquatic plants.
Anacyclus is a genus of plants in the family Asteraceae described by Linnaeus in 1753. Annuals or herbaceous perennials, they are cultivated for their fern-like leaves on creeping, radiating stems and daisy-like flowers. They are frost-hardy but may tolerate winter temperatures below −5 °C (23 °F) if grown in well-drained soil.
Harold Ernest Robinson was an American botanist and an entomologist.
Othonna is a genus of approximately 90 species of succulent or subsucculent perennial herbs or shrubs, with its center of diversity in the Greater Cape Floristic Region (GCFR) of South Africa but some species' ranges include southern Namibia, Angola, and Zimbabwe. The genus was established by Linnaeus in 1753 containing 14 species, however, of those original species, only four are still retained in Othonna, while the others have been transferred to different genera including Cineraria, Euryops, Hertia, Ligularia, Senecio, and Tephroseris. The genus Othonnna is known to be monophyletic. In 2012, a new genus Crassothonna B. Nord. was erected with 13 species transferred from Othonna. A complete modern taxonomic treatment of the genus is being undertaken by the Compton Herbarium and the South African National Biodiversity Institute. The first part, a revision of the Othonnna bulbosa group, was published in 2019.
Calenduleae is a flowering plant tribe of the family Asteraceae. Calenduleae has been widely recognized since Alexandre de Cassini in the early 19th century. There are eight genera and over 110 species, mostly found in South Africa.
Rune Bertil Nordenstam is a Swedish botanist and professor emeritus at the Swedish Museum of Natural History in the Department of Phanerogamic Botany. He has worked with Colchicaceae, Senecioneae and Calenduleae, was the editor of Compositae Newsletter newsletter since 1990, and is a Tribal Coordinator for The International Compositae Alliance with responsibility for the tribes Calenduleae and Senecioneae.
Cineraria deltoidea is a perennial flowering plant of the family Asteraceae and the genus Cineraria which is also the closest known relative of the giant Dendrosenecio of East Africa.
Antillanthus is a genus of the tribe Senecioneae in the family Asteraceae described as a genus in 2006. Many members of this genus were previously listed as Pentacalia and Senecio.
Kleinia implexa is a species of flowering plant in the genus Kleinia and family Asteraceae which was previously considered to be a species of Senecio.
Senecio invalidus is a species of the genus Senecio and family Asteraceae.
Kleinia petraea is a species of flowering plant in the genus Kleinia and family Asteraceae which was previously considered to be a species of Senecio. Native to Kenya and Tanzania, it is colloquially known as creeping jade, trailing jade or weeping jade due to its resemblance to the unrelated Jade plant. It is grown as a garden plant as a groundcover or in hanging baskets.
Curio archeri, syn. Senecio toxotis is a species of succulent plant in the family Asteraceaethat is indigenous to the south-western Cape, South Africa.
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.
Caxamarca is a genus of flowering plants in the daisy family, Asteraceae.
Homogyne is a genus of flowering plants in the daisy family, Asteraceae.
Koyamacalia was a genus of East Asian plants in the groundsel tribe Senecioneae within the daisy family Asteraceae. It is a synonym of the accepted genus Parasenecio.
Capelio is a genus of flowering plant in the Asteraceae first described as a genus in 1836 with the name Alciope. It was renamed Capelio in 2002 after it was determined that the name Alciope was not legitimately published according to international nomenclatural rules. Capelio is a taxonomic anagram derived from the former name Alciope.
Vicki Ann Funk was an American botanist and curator at the Smithsonian's National Museum of Natural History, known for her work on members of the composite family (Asteraceae) including collecting plants in many parts of the world, as well as her synthetic work on phylogenetics and biogeography.
Caputia is a small genus of flowering plants in the family Asteraceae, native to South Africa. It may be of hybrid origin. Species in this genus were formerly considered part of the genus Senecio.
