Trifolium Dubium
''Trifolium dubium'', the lesser trefoil, suckling clover, little hop clover or lesser hop trefoil, is a flowering plant in the pea and clover family Fabaceae. This species is generally accepted as the primary plant to represent the traditional Irish shamrock. It is native to Europe, but can be found in many parts of the world as an introduced species. It is probably an allotetraploid with 2n=32 that arose from the crossing of ''Trifolium campestre'' and '' T. micranthum''.Ansari, H. A., et al. (2008).

John Sibthorp
John Sibthorp (28 October 1758 – 8 February 1796) was an English botanist. Education Sibthorp graduated from the University of Oxford in 1777 where he was an undergraduate student at Lincoln College, Oxford. He subsequently studied medicine at the University of Edinburgh and University of Montpellier. Career and research In 1784, he succeeded his father to the Sherardian chair. Leaving his professional duties to a deputy, he left England for Göttingen and Vienna, in preparation for a botanical tour of Greece (1786) and Cyprus (1787). Returning to England at the end of the following year, he took part in the foundation of the Linnean Society of London in 1788, and set to work on a Flora of Oxfordshire, which was published in 1794 as ''Flora Oxoniensis''. He was elected as a Fellow of the Royal Society in Mar 1788. He made a second journey to Greece, but developed consumption on the way home and died in Bath on 8 February 1796. He was buried at Bath Abbey, with a monum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They 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. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ireland
Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest on Earth. Geopolitically, Ireland is divided between the Republic of Ireland (officially Names of the Irish state, named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million living in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islan ...

Shamrock
A shamrock is a young sprig, used as a symbol of Ireland. Saint Patrick, Ireland's patron saint, is said to have used it as a metaphor for the Christian Holy Trinity. The name ''shamrock'' comes from Irish (), which is the diminutive of the Irish word and simply means "young clover". At most times'', Shamrock'' refers to either the species (lesser clover, Irish: ) or (white clover, Irish: ). However, other three-leaved plants—such as , , and —are sometimes called shamrocks. The shamrock was traditionally used for its medicinal properties and was a popular motif in Victorian times. Botanical species There is still not a consensus over the precise botanical species of clover that is the "true" shamrock. John Gerard in his herbal of 1597 defined the shamrock as ''Trifolium pratense'' or ''Trifolium pratense flore albo'', meaning red or white clover. He described the plant in English as "Three leaved grasse" or "Medow Trefoile", "which are called in Irish ''Sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyploidy
Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei ( eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis, the sporophyte generation is diploid and produces spores by mei ...

Trifolium Campestre
''Trifolium campestre'', commonly known as hop trefoil, field clover and low hop clover, is a species of flowering plant native to Europe and western Asia, growing in dry, sandy grassland habitats, fields, woodland margins, roadsides, wastelands and cultivated land. The species name ''campestre'' means "of the fields". Description It is a herbaceous annual plant, growing to 10–30 cm tall, with distinctive yellow inflorescence, flowerheads that superficially resemble hops, hop flowers. Each flowerhead is a cylindrical or spherical collection of 20–40 individual flowers. The flowers become brown upon aging and drying, enclosing the fruit, a one-seeded pod. The leaf, leaves are alternate and trifoliate, with three oblong or elliptical leaflets 4–10 mm long. This species is very closely related to large hop trefoil (''Trifolium aureum''). Cultivation and uses Hop trefoil is an important clover in agriculture because its foliage is good for feeding livestock and re ...

Trifolium Aureum
''Trifolium aureum'', known by the various common names large hop trefoil, large trefoil, large hop clover, golden clover or hop clover, is a species of flowering plant native to much of Eurasia. Large hop trefoil is a small erect herbaceous biennial plant growing to 10–30 cm tall. Like all clovers, it has leaves divided into three sessile leaflets, each leaflet 15–25 mm long and 6–9 mm broad. Its yellow flowers are arranged into small, elongated round inflorescences 12–20 mm diameter, located at the end of the stem. Each individual flower is decumbent. As they age, the flowers become brown and paper-like. The fruit is a pod usually containing two seeds. The closely related '' Trifolium campestre'' (hop trefoil) is a similar, but shorter, spreading, species with smaller leaves and flowers. The middle leaflet of its leaves also has a short rachis. Cultivation and uses The plant is very common, and grows well on poor, undisturbed grounds. While it p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicago Lupulina
''Medicago lupulina'', commonly known as black medick, nonesuch, or hop clover, is a plant of dry grassland belonging to the legume or clover family. Plants of the genus ''Medicago'', or bur clovers, are closely related to the true clovers (''Trifolium'') and sweet clover (''Melilotus''). Like the true clovers, black medick has three leaflets and a small, yellow flower closely resembling those of lesser trefoil. Black medick belongs to the same genus as alfalfa. Names The generic name ''Medicago'' is derived, via Latin , from Ancient Greek () "Median", because alfalfa was believed to have been introduced from the region of Media (now in Iran) in antiquity. The specific name ''lupulina'' means "wolf-like", and refers to the hop, or willow-wolf. Its scientific name is a translation of the common name hop clover (or hop-clover), which is also used for several members of the genus ''Trifolium''. Also spelled "medic" or "meddick", the plant is known by a number of alternate names, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
