Calystegia Affinis
''Calystegia affinis'' is a critically endangered species of climbing or creeping vine in the plant family Convolvulaceae. It is endemic to Lord Howe Island and Norfolk Island. In 2003 only about 45 mature plants were known, with about 40 of those on Norfolk Island.Coyne, Peter. ''Norfolk Island's Fascinating Flora''. Petaurus Press, 2011, p. 61 Etymology The genus name, ''Calystegia'' is derived from the Greek: kalux, "cup", and stegos, "a covering", meaning "a covering cup" and refers to the bracteoles enclosing the calyx. The specific epithet, ''affinis'', is Latin for 'neighbouring', which was possibly chosen by Endlicher on the basis of his comment that the species was closely allied to '' Calystegia marginata''. Description ''Calystegia affinis'' is a thin-stemmed plant in the genus ''Calystegia'' which climbs by twining. It has sparse alternate, arrow-headed leaves about 6 cm x 5 cm. The flowers are axillary, solitary, pink with five cream longitudinal bands a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calystegia
''Calystegia'' (bindweed, false bindweed, or morning glory) is a genus of about 25 species of flowering plants in the bindweed family Convolvulaceae. The genus has a cosmopolitan distribution in temperate and subtropical regions, but with half of the species endemic to California. They are annual or herbaceous perennial twining vines growing 1–5 m tall, with spirally arranged leaves. The flowers are trumpet-shaped, 3–10 cm diameter, white or pink, with (in most species) a sometimes inflated basal epicalyx. The genus bears much similarity to a related genus ''Convolvulus'', and is sometimes combined with it; it is distinguished primarily by the pollen being smooth, and in the ovary being unilocular. Some of the species, notably ''Calystegia sepium'' and '' C. silvatica'', are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers. ''Calystegia'' species are eaten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic an ...

Convolvulaceae
Convolvulaceae (), commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato. Description Convolvulaceae can be recognized by their funnel-shaped, radially symmetrical corolla; the floral formula for the family has five sepals, five fused petals, five epipetalous stamens (stamens fused to the petals), and a two-part syncarpous and superior gynoecium. The stems of these plants are usually winding, hence their Latin name (from ''convolvere'', "to wind"). The leaves are simple and alternate, without stipules. In parasitic Cuscuta (dodder) they are reduced to scales. The fruit can be a capsule, berry, or nut, all containing only two seeds per one locule (one ovule/ovary). The leaves and starchy, tuberous roots of some species are used as foodstuffs (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first report ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk Island
Norfolk Island (, ; Norfuk: ''Norf'k Ailen'') is an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia, directly east of Australia's Evans Head and about from Lord Howe Island. Together with the neighbouring Phillip Island and Nepean Island, the three islands collectively form the Territory of Norfolk Island. At the 2021 census, it had inhabitants living on a total area of about . Its capital is Kingston. The first known settlers in Norfolk Island were East Polynesians but they had already departed when Great Britain settled it as part of its 1788 settlement of Australia. The island served as a convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when it lay abandoned. On 8 June 1856, permanent civilian residence on the island began when descendants of the ''Bounty'' mutineers were relocated from Pitcairn Island. In 1914 the UK handed No ...

Bracteoles
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyx (flower)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, a ...

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephan Endlicher
Stephan Ladislaus Endlicher also known as Endlicher István László (24 June 1804, Bratislava (Pozsony) – 28 March 1849, Vienna) was an Austrian botanist, numismatist and Sinologist. He was a director of the Botanical Garden of Vienna. Biography Endlicher studied theology and received minor orders. In 1828 he was appointed to the Austrian National Library to reorganize its manuscript collection. Concurrently he studied natural history, in particular botany, and East-Asian languages. In 1836, Endlicher was appointed keeper of the court cabinet of natural history, and in 1840 he became professor at the University of Vienna and director of its Botanical Garden. He wrote a comprehensive description of the plant kingdom according to a natural system, at the time its most comprehensive description. As proposed by Endlicher, it contained images with text. It was published together with the reissue of Franz Unger's ''Grundzüge der Botanik'' (Fundamentals of Botany). Endliche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calystegia Marginata
''Calystegia marginata'' is a species of morning glory, found in eastern Australia and New Zealand. A hairless and vigorous perennial climbing plant, with twining stems. The habitat is moist gullies in sclerophyll forest and on rainforest margins, widespread on the coast and ranges of eastern Australia.This is one of the many plants first published by Robert Brown with the type known as "(J.) v.v." appearing in his ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' in 1810. The specific epithet ''marginata'' is derived from Latin, probably referring to the habitat being the margins of rainforest Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainfores ...s.Les Robinson – Field Guide to the Native Plants of Sydney, page 330 References Calystegia Plants described in 1810 ...

Joseph Maiden
Joseph Henry Maiden (25 April 1859 – 16 November 1925) was a botanist who made a major contribution to knowledge of the Australian flora, especially the genus '' Eucalyptus''. This botanist is denoted by the author abbreviation when citing a botanical name. Life Joseph Maiden was born in St John's Wood in northwest London. He studied science at the University of London, but due to ill health he did not complete the course. As part of his treatment he was advised to take a long sea voyage, and so in 1880 he sailed for New South Wales. In 1881, Maiden was appointed first curator of the Technological Museum in Sydney (now the Powerhouse Museum), remaining there until 1896. While there, he published an article in 1886 describing what he called "some sixteenth century maps of Australia". These were the so-called Dieppe maps, the Rotz (1547), the Harleian or Dauphin (mid-1540s), and the Desceliers (1550), photo-lithographic reproductions of which had been published by the ...
