Senecioneae is the largest tribe of Asteraceae, comprised of approximately 150 genera and 3,000 species. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its The Asterales are an order of Dicotyledonous Flowering plants which include the composite family Asteraceae ( Sunflowers daisies The family Asteraceae or Compositae (known as the aster, daisy, or sunflower family) is the largest family of Flowering Count Alexandre Henri Gabriel de Cassini (1781-1832 was a French Botanist and naturalist, who specialised in the sunflower family ( Asteraceae) (then known In Biology, a tribe &mdashor infrafamily&mdashis a Taxonomic rank between family and Genus. The family Asteraceae or Compositae (known as the aster, daisy, or sunflower family) is the largest family of Flowering Almost one-third of its species are placed in the genus Senecio, making it one of the largest genera of flowering plants. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic Senecio is a Genus of the daisy family ( Asteraceae)that includes ragworts and groundsels. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group [1] Its members exhibit probably the widest possible range of form to be found anywhere in the entire plant kingdom and include annuals, minute creeping alpines, perennial herbs, shrubs, climbers, succulents, trees and semi-aquatic plants. Botanically an annual plant is a Plant that usually germinates, Flowers and dies in one Year. A perennial plant or perennial ( Latin per, "through" annus, "year" is a Plant that lives for more than A shrub or Bush is a horticultural rather than strictly botanical category of Woody plant, distinguished from a Tree A vine is any plant of Genus Vitis (the Grape plants or by extension any similar climbing or trailing plant Succulent plants, also known as succulents or fat plants, are Water -retaining Plants adapted to Arid climate or Soil conditions A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or Aquatic plants &mdash also called hydrophytic plants or hydrophytes &mdash are plants that have adapted to living in or on aquatic environments [2].

Plants in this tribe are responsible for more livestock poisonings than all other plants combined. [3] The poisons are particularly pyrrolizidine alkaloids in Senecio[3] and furanoeremophilanes in Tetradymia[2]. Pyrrolizidine is a Heterocyclic Organic compound that forms the central chemical structure of a variety of Alkaloids known collectively as Pyrrolizidine This article is about the chemical compounds alkaloids For the Pharmaceutical company in the Republic of Macedonia see Alkaloid (company. Senecio is a Genus of the daisy family ( Asteraceae)that includes ragworts and groundsels.

A number of species are well-known in horticulture. Horticulture is the art and science of plant cultivation Horticulturists (or horticuluralists) work and conduct research in the fields of Plant propagation [2]

Classification

Since the time days of Bentham, the "premier systematic botanist of the nineteenth century"[4] considerable efforts have been made to classify and understand the striking morphological diversity in Senecioneae. George Bentham CMG FRS ( September 22, 1800 &ndash September 10, 1884) was an English Botanist, characterized by Duane Isely Plant morphology (or phytomorphology) is the general term for the study of the morphology (physical form and external structure of Plants This is usually [1] The traditional view of the tribe has been that of one huge genus Senecio plus many other genera which exhibit varying degrees of distinctiveness. Senecio is a Genus of the daisy family ( Asteraceae)that includes ragworts and groundsels. [4] Circumscription and delimitation of the tribe has experienced expansions and contractions over the decades as genera and groups of genera have been moved in and out,[2] as was the case for Arnica, Liabum, Munnozia, Schistocarpha, etc. Arnica ( Ár-ni-ca) is a genus with about 30 perennial, herbaceous species belonging to the sunflower family ( Asteraceae) UserPolbot. --> Liabum is a genus of Flowering plant in the Asteraceae family UserPolbot. --> Munnozia is a genus of Flowering plant in the Asteraceae family which have since then been excluded. [4] Of the several potential causes for this constant redefinition the greatest is probably that little is known about its intergeneric relationships or a lack of phylogenetic understanding enhanced by the other problems of conflicting clues from morphological characters, the large size of the tribe, the absence of a precise delimitation or circumscription of Senecio[1] and the naturalness of these assemblages combined with the imprecise boundaries of the different species themselves. In Biology, hybrid has two meanings The first meaning is the result of interbreeding between two animals or plants of different taxa. [4]

Many segregate genera have been recognized in recent studies, often with circumscriptions derived from selected representative species. It is yet unclear that the recognition of numerous segregate genera provides a better taxonomy than treating the variation patterns as infrageneric taxa. In Taxonomy, a type species is the species that originally defined a genus. A respectable case can be made for maintaining Senecio as a broad concept, at least until revisionary studies at the species level are carried out and the results subjected to critical analyses. [4] Most genera that have been removed from Senecioneae in its broadest sense have come to rest within Liabeae or within a broadly circumscribed Heliantheae (e. The tribe Heliantheae is the most familiar tribe of the Sunflower family ( Asteraceae) g. , allies in Arnicinae, Chaenactidinae, or Madiinae; Haploësthes in Flaveriinae; Raillardella and allies in Madiinae).
