The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown.
Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific Latin genus name, Senecio, means "old man".
The Pentatomoidea are a superfamily of insects in the Heteroptera suborder of the Hemiptera order. As Hemiptera, they share a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families. Among these are the shield bugs, giant shield bugs, burrower bugs, and stink bugs.
Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", however true groundsels are found in the genus Senecio.
Senecio pulcher is an ornamental plant native to the wet valleys & slopes and flooded rocky habitats in Argentina, Brazil, and Uruguay. Cited in Flora Brasiliensis by Carl Friedrich Philipp von Martius. After dusty miller, S. pulcher is perhaps one of the most popular species of the genus for horticulture along with German ivy and purple ragwort or it was in 1917.
Senecio ampullaceus, also known as Texas ragwort, Texas squaw-weed, Texas groundsel, and Texas butterweed, is a species of Senecio in the family Asteraceae, receiving its Latin name ampullaceus from its flask shaped flower-head. It is recommended for landscape use in its native Texas.
Dendrosenecio keniodendron or giant groundsel is a species of the genus Dendrosenecio of the large family Asteraceae and is one of the several species of giant groundsels endemic to the high altitudes of the Afrotropic, including Dendrosenecio johnstonii (Senecio battiscombei) occurring on Mount Kilimanjaro, Mount Kenya, and the Aberdare Mountains, Dendrosenecio keniensis occurring the lower alpine zone of Mount Kenya and D. keniodendron occurring in higher and drier sites on Mount Kenya. The giant rosette plants, sometimes 6 metres (20 ft) tall, often grow in even-sized stands, with different understory communities under different-aged stands.
Senecio squalidus, known as Oxford ragwort, is a flowering plant in the daisy family Asteraceae. It is a yellow-flowered herbaceous plant, native to mountainous, rocky or volcanic areas, that has managed to find other homes on man-made and natural piles of rocks, war-ruined neighborhoods and even on stone walls. These habitats resemble its well drained natural rocky homeland. The plants have spread via the wind, rail and the activities of botanists. The travels of this short-lived perennial, biennial, or winter annual make it a good subject for studies of the evolution and ecology of flowering plants.
Senecio gallicus, an annual plant of the genus Senecio and family Asteraceae, is a species that colonizes isolated habitats with difficult environmental conditions. It is widespread across southern France and the Iberian Peninsula in deserts and xeric shrublands, on steppes and salty dry coastal plains. S. gallicus is playing a predominant role in shaping patterns of genetic structure by presenting models of historical associations among population rather than patterns of ongoing gene flow.
Brachyglottis greyi, commonly known as daisy bush, is a member of the large family Asteraceae and belongs to the genus Brachyglottis or the genus Senecio depending on which authority is being followed, an endemic native of New Zealand and lately getting positive attention from gardeners.
Senecio angulatus, also known as creeping groundsel and sometimes as Cape ivy, is a succulent plant from the family Asteraceae of the genus Senecio that is native to South Africa. It is a scrambling and a twining herb that can become an aggressive weed once established, making it an invasive species in some countries. However, it is grown as an ornamental plant for its satiny foliage and sweet-scented flowers.
Senecio tamoides, also known as Canary creeper, is a climbing member of the genus Senecio of the family Asteraceae that is native to Southern Africa. It is used as an ornamental plant for its showy yellow, daisy-like flowers in autumn.
Senecio crassiflorus, in Portuguese: margarida-das-dunas, one of the native South American Senecio and an herbaceous dune dwelling perennial.
Hydrocotyle bonariensis, the largeleaf pennywort, once a member of the family Apiaceae, now in the family Araliaceae and of the genus Hydrocotyle, is a hairless and creeping perennial.
Senecio madagascariensis, also known as Madagascar ragwort, is a species of the genus Senecio and family Asteraceae that is native to Southern Africa. Other common names include Madagascar groundsel and fireweed. It has been included on the noxious weeds list for Hawaii and the reject list for Australia. S.madagascariensis is the diploid cytotype of S.inaequidens.
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.
Senecio ovatus, common name wood ragwort, is a perennial herbaceous plant belonging to the family Asteraceae.
Brachyglottis monroi is a species of plant in the family Asteraceae, formerly classified in the genus Senecio. Native to New Zealand and Tasmania, it is a small, hardy, evergreen shrub growing to 1 m with crinkly-edged, olive green, leathery leaves and yellow daisy-like flowers in terminal corymbs in summer.
Artemisia gorgonum is a species of flowering plants of the family Asteraceae, endemic to Cape Verde. Its local name is losna or lasna. The plant plays a role in traditional medicine.
Senecio linearifolius, commonly known as fireweed groundsel,is a species of flowering plant in the family Asteraceae. It is a small shrub with variable leaves, numerous heads of yellow flowers and grows in Tasmania, New South Wales and Victoria.
