Oxalis
''Oxalis'' ( (American English) or (British English)) is a large genus of flowering plants in the wood-sorrel family Oxalidaceae, comprising over 550 species. The genus occurs throughout most of the world, except for the Polar region, polar areas; species diversity is particularly rich in tropical Brazil, Mexico, and South Africa. Many of the species are known as wood sorrels (sometimes written "woodsorrels" or "wood-sorrels") as they have an acidic taste reminiscent of the sorrel proper (''Rumex acetosa''), which is only distantly related. Some species are called yellow sorrels or pink sorrels after the color of their flowers instead. Other species are colloquially known as false shamrocks, and some called sourgrasses. For the genus as a whole, the term oxalises is also used. Description and ecology These plants are annual plant, annual or perennial plant, perennial. The leaves are divided into three to ten or more obovate and top-notched leaflets, arranged palmately with all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oxalis Acetosella
''Oxalis acetosella'', the wood sorrel or common wood sorrel, is a rhizomatous flowering plant in the family ''Oxalidaceae'', common in most of Europe and parts of Asia. The specific epithet ''acetosella'' refers to its sour taste. The common name wood sorrel is often used for other plants in the genus ''Oxalis''. In much of its range it is the only member of its genus and hence simply known as "the" wood sorrel. While common wood sorrel may be used to differentiate it from most other species of ''Oxalis'', in North America, ''Oxalis montana'' is also called common wood sorrel. It is also known as ''Alleluia'' because it blossoms between Easter and Pentecost, when the Psalms which end with Hallelujah are sung. Description The plant has trifoliate compound leaves, the leaflets heart-shaped and folded through the middle, that occur in groups of three on petioles up to long. It flowers from spring to midsummer with small white chasmogamous flowers with pink streaks. Red or viole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Oxalidaceae
The Oxalidaceae, or wood sorrel family, are a small family of five genera of herbaceous plants, shrubs and small trees, with the great majority of the 570 species in the genus ''Oxalis'' (wood sorrels). Members of this family typically have divided leaves A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, st ..., the leaflets showing "sleep movements", spreading open in light and closing in darkness. The genus ''Averrhoa'' of which starfruit is a member, is usually included in this family (e.g. APG IV, 2016), but some botanists place it in a separate family Averrhoaceae.

Clover
Clover or trefoil are common names for plants of the genus ''Trifolium'' (from Latin ''tres'' 'three' + ''folium'' 'leaf'), consisting of about 300 species of flowering plants in the legume or pea family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate (rarely quatrefoiled; see four-leaf clover), monofoil, bifoil, cinquefoil, hexafoil, septfoil, etcetera, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include ''Melilotus'' (sweet clover) and '' Medicago'' ( alfalfa or Calva ...

Sydney Turpentine-Ironbark Forest
The Sydney Turpentine-Ironbark Forest (STIF) is dry sclerophyll forest community of Sydney, New South Wales, Australia, that is typically found in the Inner West and Northern region of Sydney. It is also among the three of these plant communities which have been classified as Endangered, under the New South Wales government's ''Threatened Species Conservation Act 1995'', with only around 0.5% of its original pre-settlement range remaining. As of 26 August 2005, the Australian Government reclassified Sydney Turpentine-Ironbark Forest as a "Critically Endangered Ecological Community", under the Commonwealth's ''Environment Protection and Biodiversity Conservation Act 1999''. The original extent of the forest was 26,516 ha, but now only 1,182 ha (or 4.5% of original extent) remains. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photoinhibition
Photoinhibition is light-induced reduction in the photosynthetic capacity of a plant, alga, or cyanobacterium. Photosystem II (PSII) is more sensitive to light than the rest of the photosynthetic machinery, and most researchers define the term as light-induced damage to PSII. In living organisms, photoinhibited PSII centres are continuously repaired via degradation and synthesis of the D1 protein of the photosynthetic reaction center of PSII. Photoinhibition is also used in a wider sense, as dynamic photoinhibition, to describe all reactions that decrease the efficiency of photosynthesis when plants are exposed to light. History The first measurements of photoinhibition were published in 1956 by Bessel Kok. Even in the very first studies, it was obvious that plants have a repair mechanism that continuously repairs photoinhibitory damage. In 1966, Jones and Kok measured the action spectrum of photoinhibition and found that ultraviolet light is highly photoinhibitory. The visible-li ...
