Dendroseris Lacerata
''Sonchus'' subg. ''Dendroseris'' is a subgenus of flowering plants in the genus ''Sonchus'', family Asteraceae. It was formerly treated as the genus ''Dendroseris'', with one species sometimes placed in ''Thamnoseris''. All the species placed in the subgenus are endemic to either the Juan Fernández Islands or the Desventuradas Islands in the South Pacific, both part of Chile. Description Species of ''Sonchus'' subg. ''Dendroseris'' have an unusual growth habit for members of the genus. They are shrubs or trees, some up to high. The shrubby species are succulent, the tree-like species are either unbranched or weakly branched. They have large leaves, either entire or lobed (pinnatifid), arranged in rosettes. The base of the flower head (the receptacle) does not have scales. The flowers are white to orange in colour. The achenes are usually flattened and irregularly shaped. The pappus is made up of relatively few, stiff and non-feathered hairs. The species are tetraploids, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonchus Brassicifolius
''Sonchus brassicifolius'', Synonym (taxonomy), synonym ''Dendroseris litoralis'', is a species of flowering plant in the daisy and sunflower family Asteraceae. It is a small evergreen tree species known as the cabbage tree. It is Endemism, endemic to the Juan Fernández Islands, which lie in the southeast Pacific, off the west coast of Chile. It is native only to the tiny, volcanic Robinson Crusoe Island, home of the famed ''Juania, Juania australis'' and many other endemic plants. The species is threatened by habitat loss and has been brought back from the brink of extinction. It had been reduced to only a few individuals by feral goats on the island, and is still considered critically endangered. Description Younger trunks of ''Sonchus brassicifolius'' are ringed with pale leaf scars and distinctive rubbery, leathery leaves up to long. It grows into a small, gnarled tree with several somewhat palm-like crowns of very large, ovate leaves on whitish, green-spotted leaf stalks an ...

Sonchus Splendens
''Sonchus splendens'', synonym ''Dendroseris macrophylla'', is a species of flowering plant in the family Asteraceae. It is endemic to the Juan Fernández Islands of Chile. It is threatened by habitat loss. Taxonomy The species was first described in 1832 by David Don as ''Dendroseris macrophylla''. In 2012, based on molecular phylogenetic evidence, it was shown that ''Dendroseris'' was embedded within the genus ''Sonchus'', and all its species were transferred to that genus, placed in ''Sonchus'' subg. ''Dendroseris''. As the combination ''Sonchus macrophyllus'' had already been used for a different species, the replacement name In biological nomenclature, a ''nomen novum'' ( Latin for "new name"), new replacement name (or replacement name, new substitute name, substitute name) is a scientific name that is created specifically to replace another scientific name, but only ...

Sonchus Sinuatus
''Sonchus'' is a genus of flowering plants in the tribe Cichorieae within the family Asteraceae and are commonly known as sow thistles (less commonly hare thistles or hare lettuces). Sowthistles are annual, biennial or perennial herbs, with or without rhizomes and a few are even woody (subgenus ''Dendrosonchus,'' restricted to the Canary Islands and Madeira). Description The genus is named after the Ancient Greek for such plants. All are characterized by soft, somewhat irregularly lobed leaves that clasp the stem and, at least initially, form a basal rosette. The stem contains a milky latex. Flower heads are yellow and range in size from half to one inch in diameter; the florets are all of ray type. ''Sonchus'' fruits are single-seeded, dry and indehiscent. Sow thistles are common roadside plants, and while native to Eurasia and tropical Africa, they are found almost worldwide in temperate regions. Mature sow thistle stems can range from 30 cm to 2 m (1 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
