Scapisenecio is a genus of flowering plant in the family Asteraceae, native to south-eastern Australia, particularly Tasmania. [2] The genus was established in 2020. [1]
Species of Scapisenecio are rhizomatous or stoloniferous herbaceous plants. Their fully developed leaves are located close to the base of the plant, often in a rosette. The flowering heads are borne on stems with smaller leaves, usually one flower head per stem. The ray florets are yellow or more rarely white. [3]
The genus Scapisenecio was established in 2020. A molecular phylogenetic study of Australian species placed in the tribe Senecioneae found that five species then placed in Senecio formed a clade that was clearly distinct from other Senecio species, genetically, morphologically, and in their distribution and ecology. Accordingly, a new genus was erected to include these five Australian species. The genus name refers to the growth habit in which the flower heads are borne on stems with reduced leaves (scapes). [3]
As of January 2023 [update] , Plants of the World Online accepted the following species: [2]
All the species of Scapisenecio are native to Tasmania. S. pectinatus is also found on the Australian mainland in New South Wales and Victoria; the other species are endemic to Tasmania. They are all found in subalpine to alpine habitats. [3]
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.
Craspedia is a genus of flowering plants in the family Asteraceae commonly known as billy buttons, billy balls, and woollyheads. They are native to Australia and New Zealand where they grow in a variety of habitats from sea level to the Alps. The genus is found in every state of Australia but not in the Northern Territory. In New Zealand, Craspedia is found from East Cape on the North Island south to Stewart Island. It also occurs on Campbell Island and the Chatham Islands.
Pycnosorus is a genus of six species of plants in the family Asteraceae. Commonly known as billy buttons or drumsticks, they are annual or perennial herbs or small shrubs with a cylindrical to spherical head of up to 200 daisy-like "flowers". Each "flower" is a pseudanthium consisting of between three and eight florets surrounded by bracts. The petals are joined to form a small tube and the florets with their surrounding bracts are yellow or golden-yellow.
Bedfordia is a genus of flowering plants belonging to the family Asteraceae. The genus includes 3 species, all endemic to Australia.
Brachyglottis is a genus of flowering plants in the family Asteraceae. The genus was erected on November 29, 1775, by Johann Reinhold Forster and Georg Forster. The name was derived from the Greek brachus ("short") and glottis a reference to the size of the ray florets.
Erechtites is a genus of flowering plants in the daisy family known commonly as fireweeds or burnweeds. They are native to the Americas and Australia, but some species are widely distributed weeds.
Senecio tamoides, also known as Canary creeper, false grapevine, and parlor ivy, 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 late autumn through to winter.
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.
Roldana petasitis, also known as the velvet groundsel or Californian geranium, is a species of the genus Roldana and family Asteraceae that used to be classified in the genus Senecio. It is native to Central America.
x Senecurio kleiniiformis is a hybrid species of flowering plant in family Asteraceae. It has been placed in either the genus Senecio, as Senecio × kleiniiformis, or Kleinia, but is now thought to be a hybrid between an unknown species of Curio and Senecio tropaeolifolius. It was initially named Curio × kleiniiformis, but in 2020 the hybrid genus Senecurio was created for it.
Barkleyanthus is a monotypic genus of flowering plants in the aster family, Asteraceae, containing the single species Barkleyanthus salicifolius, a plant formerly classified in the genus Senecio. It is native to North and Central America, where its distribution extends from the southwestern United States to El Salvador. Its common names include willow ragwort, willow groundsel, Barkley's-ragwort, and jarilla.
Packera musiniensis is a rare species of flowering plant in the aster family known by the common names Musinea ragwort and Musinea groundsel. It is endemic to Utah in the United States, where it is known only from Sanpete County in the Manti-La Sal National Forest.
Scapisenecio pectinatus, synonym Senecio pectinatus, commonly known as alpine groundsel, is a species of flowering plant in the aster family. The species occurs in alpine areas of south-eastern Australia in peat-based soils. It has divided leaves forming a basal rosette and produces a single yellow flower head on a stalk up to 20 cm high.
Lordhowea velleioides, synonym Senecio velleioides, is a species of flowering plant in the family Asteraceae. It is commonly known as forest groundsel.
Lordhowea amygdalifolia, synonym Senecio amygdalifolius, is a species of flowering plant in the daisy family (Asteraceae). It occurs in the Australian states of New South Wales and Queensland, in wet eucalyptus forest or around the margins of rainforest. Ferdinand von Mueller first described it in 1859, as Senecio amygdalifolius, from a collection made by Dr. Hermann Beckler, near the Hastings River.
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.
Senecio minimus, commonly known as toothed fireweed and coastal burnweed, is a species of plant in the sunflower family. It is native to Australia and New Zealand, and also naturalized on the Pacific Coast of the United States.
Senecio gregorii, commonly known as annual yellowtop or fleshy groundsel, is a native Australian wildflower species, found in arid and semi-arid regions of the Australia and across the globe. It often grows prolifically after autumn/winter rains, showcasing stunning yellow flowers and fleshy foliage. The scientific name of this species was first published by Ferdinand von Mueller.
Lordhowea is a genus of flowering plant in the family Asteraceae, native to eastern and south-eastern Australia and Lord Howe Island. The genus was established by Bertil Nordenstam in 1978.
