Bidens is a genus of flowering plants in the aster family, Asteraceae. The genus include roughly 230 species which are distributed worldwide. Despite their global distribution, the systematics and taxonomy of the genus has been described as complicated and unorganized. The common names beggarticks, black jack, burr marigolds, cobbler's pegs, Spanish needles, stickseeds, tickseeds and tickseed sunflowers refer to the fruits of the plants, most of which are bristly and barbed. The generic name refers to the same character; Bidens comes from the Latin bis ("two") and dens ("tooth").
Crambe is a genus of annual and perennial flowering plants in the family Brassicaceae, native to a variety of habitats in Europe, Turkey, southwest and central Asia and eastern Africa.

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.

Gerbera L. is a genus of plants in the Asteraceae (Compositae) family. The first scientific description of a Gerbera was made by J. D. Hooker in Curtis's Botanical Magazine in 1889 when he described Gerbera jamesonii, a South African species also known as Transvaal daisy or Barberton daisy. Gerbera is also commonly known as the African daisy.
Gerbera jamesonii is a species of flowering plant in the genus Gerbera belonging to the basal Mutisieae tribe within the large Asteraceae family. It is indigenous to South Eastern Africa and commonly known as the Barberton daisy, the Transvaal daisy, and as Barbertonse madeliefie or Rooigousblom in Afrikaans. It was the first species of Gerbera to be the subject of a scientific description, studied by J. D. Hooker in Curtis's Botanical Magazine in 1889.
Pericallis × hybrida, known as cineraria, florist's cineraria or common ragwort is a flowering plant in the family Asteraceae. It originated as a hybrid between Pericallis cruenta and P. lanata, both natives of the Canary Islands. The hybrid was first developed in the British royal gardens in 1777. It was originally known as Cineraria × hybrida, but the genus Cineraria is now restricted to a group of South African species, with the Canary Island species being transferred to the genus Pericallis; some botanists also treat it in a broad view of the large and widespread genus Senecio. Some varieties are sold under the trade name Senetti.
Cineraria is a genus of flowering plants in the sunflower family, native primarily to southern Africa with a few species farther north. The genus includes herbaceous plants and small subshrubs.
Jacobaea maritima, commonly known as silver ragwort, is a perennial plant species in the genus Jacobaea in the family Asteraceae, native to the Mediterranean region. It was formerly placed in the genus Senecio, and is still widely referred to as Senecio cineraria; see the list of synonyms (right) for other names.
Mutisia is a genus of flowering plant in the tribe Mutisieae within the family Asteraceae. Mutisia has been named after José Celestino Mutis. It comprises about sixty species which can be found along the entire length of the Andes and in southern Brazil, Paraguay, Uruguay and northern Argentina.
Oedera is a genus of African flowering plants in the tribe Gnaphalieae within the family Asteraceae. The genus is named in honor of the Danish botanist Georg Christian Oeder.
Bystropogon is a genus of evergreen shrubs in the family Lamiaceae. It is native to the Canary Islands and Madeira in the eastern Atlantic Ocean. Allied to the Origanum and Thymus, the genus is characterized by tiny flowers in much-branched clusters, with plume-like sepals that elongate at the fruiting stage, giving the whole tip of each branch a fuzzy appearance. Stems are square in cross-section and leaves, arranged in opposite pairs, are aromatic when crushed.
Pericallis malvifolia is a species of flowering plant in the daisy family Asteraceae endemic to the Azores. It is found in coastal cliffs, ravines and interior of craters.
