Flowering plant Basal angiosperms Core angiosperms Flowering plants are plants that bear flowers and fruits , and form the clade Angiospermae ( / ˌ æ n dʒ i ə ˈ s p ər m iː / ). The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that
115-610: A total of 64 angiosperm orders and 416 families. The diversity of flowering plants is not evenly distributed. Nearly all species belong to the eudicot (75%), monocot (23%), and magnoliid (2%) clades. The remaining five clades contain a little over 250 species in total; i.e. less than 0.1% of flowering plant diversity, divided among nine families. The 25 most species-rich of 443 families, containing over 166,000 species between them in their APG circumscriptions, are: The botanical term "angiosperm", from Greek words angeíon ( ἀγγεῖον 'bottle, vessel') and spérma ( σπέρμα 'seed'),
138-858: Is starting to impact plants and is likely to cause many species to become extinct by 2100. Angiosperms are terrestrial vascular plants; like the gymnosperms, they have roots , stems , leaves , and seeds . They differ from other seed plants in several ways. The largest angiosperms are Eucalyptus gum trees of Australia, and Shorea faguetiana , dipterocarp rainforest trees of Southeast Asia, both of which can reach almost 100 metres (330 ft) in height. The smallest are Wolffia duckweeds which float on freshwater, each plant less than 2 millimetres (0.08 in) across. Considering their method of obtaining energy, some 99% of flowering plants are photosynthetic autotrophs , deriving their energy from sunlight and using it to create molecules such as sugars . The remainder are parasitic , whether on fungi like

It is on the North Coast railway line , completed to Glenreagh in 1915. A picturesque branch was opened from Glenreagh to Dorrigo in 1924, but was difficult to maintain due to the steep terrain and high rainfall and it
184-408: Is derived from kai'mia (anglicised as Gymea ) in the indigenous Dharawal language . The Sydney suburbs of Gymea and Gymea Bay are named after the lily. Gymea lilies have a rosette of large numbers of sword-shaped, strap like leaves 1–2.5 metres (3–8 ft) long and 10 centimetres (4 in) wide. The leaves are bright green, fibrous and glabrous . In winter the flower spike grows from
207-485: The Alismatales grow in marine environments, spreading with rhizomes that grow through the mud in sheltered coastal waters. Some specialised angiosperms are able to flourish in extremely acid or alkaline habitats. The sundews , many of which live in nutrient-poor acid bogs , are carnivorous plants , able to derive nutrients such as nitrate from the bodies of trapped insects. Other flowers such as Gentiana verna ,
230-460: The orchids for part or all of their life-cycle, or on other plants , either wholly like the broomrapes, Orobanche , or partially like the witchweeds, Striga . In terms of their environment, flowering plants are cosmopolitan, occupying a wide range of habitats on land, in fresh water and in the sea. On land, they are the dominant plant group in every habitat except for frigid moss-lichen tundra and coniferous forest . The seagrasses in
253-481: The seeds are enclosed within a fruit. The group was formerly called Magnoliophyta . Angiosperms are by far the most diverse group of land plants with 64 orders , 416 families , approximately 13,000 known genera and 300,000 known species . They include all forbs (flowering plants without a woody stem ), grasses and grass-like plants, a vast majority of broad-leaved trees , shrubs and vines , and most aquatic plants . Angiosperms are distinguished from

#1732858402058276-634: The type specimen collected by George Bass "in mountainous parts of the colony of N.S.W.". The description was published in Transactions of the Linnean Society of London . The genus name ( Doryanthes ) is derived from the Ancient Greek δόρυ (dóry) meaning a "spear" and ἄνθος (ánthos) meaning "a flower". The specific epithet ( excelsa ) is a Latin word meaning "high", "lofty" or "distinguished". Doryanthes excelsa and Doryanthes palmeri are
299-883: The "Big Five" extinction events in Earth's history, only the Cretaceous–Paleogene extinction event had occurred while angiosperms dominated plant life on the planet. Today, the Holocene extinction affects all kingdoms of complex life on Earth, and conservation measures are necessary to protect plants in their habitats in the wild ( in situ ), or failing that, ex situ in seed banks or artificial habitats like botanic gardens . Otherwise, around 40% of plant species may become extinct due to human actions such as habitat destruction , introduction of invasive species , unsustainable logging , land clearing and overharvesting of medicinal or ornamental plants . Further, climate change

At the top of the spike, a head of flowers 30 centimetres (10 in) in diameter develops, each flower being bright red, trumpet -shaped and about 10 centimetres (4 in) long. The head is surrounded by reddish-brown bracts , sometimes making it difficult to see
345-813: The dominant group of plants across the planet. Agriculture is almost entirely dependent on angiosperms, and a small number of flowering plant families supply nearly all plant-based food and livestock feed. Rice , maize and wheat provide half of the world's staple calorie intake, and all three plants are cereals from the Poaceae family (colloquially known as grasses). Other families provide important industrial plant products such as wood , paper and cotton , and supply numerous ingredients for beverages , sugar production , traditional medicine and modern pharmaceuticals . Flowering plants are also commonly grown for decorative purposes , with certain flowers playing significant cultural roles in many societies. Out of
368-635: The flowering plants as an unranked clade without a formal Latin name (angiosperms). A formal classification was published alongside the 2009 revision in which the flowering plants rank as the subclass Magnoliidae. From 1998, the Angiosperm Phylogeny Group (APG) has reclassified the angiosperms, with updates in the APG II system in 2003, the APG III system in 2009, and the APG IV system in 2016. In 2019,
391-498: The flowers from the ground. Flowering occurs in spring and is followed by oval-shaped reddish-brown capsules , 7–10 centimetres (3–4 in) long. In late summer, the capsule splits open and releases the seeds which are 15–23 millimetres (0.6–0.9 in) long. The flowers are pollinated by bees and nectar-feeding birds. Doryanthes excelsa was first formally described in 1802 by the Portuguese polymath , José Correia da Serra from
414-518: The manner of vines or lianas . The number of species of flowering plants is estimated to be in the range of 250,000 to 400,000. This compares to around 12,000 species of moss and 11,000 species of pteridophytes . The APG system seeks to determine the number of families , mostly by molecular phylogenetics . In the 2009 APG III there were 415 families. The 2016 APG IV added five new orders (Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, for
437-579: The most genetically divergent. Aboriginal people roasted the young stems of gymea lily for eating. They also roasted the roots to make a kind of cake. Fibres from the leaves were used for making brushes and matting. Gymea lilies are hardy and adaptable plants often used in landscape gardening , not only in the Sydney region but also in other coastal areas such as Brisbane and Perth . Plants can be grown from seed but may not flower for up to eight years. Flowering can be encouraged by fire and by carefully placing
460-854: The only two members of the family Doryanthaceae. "Doryanthes" has inspired the naming of the journal of history and heritage for Southern Sydney founded by Dharawal historian Les Bursill . Doryanthes excelsa requires very specific conditions in order to flourish. It requires low-nutrient, acidic soils with a pH of about 4.1 that are moderately deep, sandy, and earthy. It grows specifically on slopes that face south or southeast, along creeks, gullies or sheltered plateaus and ridges, at elevations of 100–200 metres above sea level. The plant grows in open dry sclerophyll forests which also have Angophora costata , Eucalyptus piperita , E. gummifera , E. sieberi , or E. punctata , as well as in habitats with Xanthorrhoea , Telopea , and moisture-preferring groundcover plant species. Doryanthes excelsa has

As for their growth habit , the flowering plants range from small, soft herbaceous plants , often living as annuals or biennials that set seed and die after one growing season, to large perennial woody trees that may live for many centuries and grow to many metres in height. Some species grow tall without being self-supporting like trees by climbing on other plants in
529-483: Was coined in the form "Angiospermae" by Paul Hermann in 1690, including only flowering plants whose seeds were enclosed in capsules. The term angiosperm fundamentally changed in meaning in 1827 with Robert Brown , when angiosperm came to mean a seed plant with enclosed ovules. In 1851, with Wilhelm Hofmeister 's work on embryo-sacs, Angiosperm came to have its modern meaning of all the flowering plants including Dicotyledons and Monocotyledons. The APG system treats
