Oxalis
''Oxalis'' ( (British English) or (American 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 areas; species diversity is particularly rich in tropical Brazil, Mexico, and South Africa. Many of the species are known as wood-sorrels (also as wood sorrels or woodsorrels) as they have an acidic taste reminiscent of the sorrel proper (''Rumex acetosa''), which is not closely related. Some species are called yellow sorrels or pink sorrels after the colour 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 The plants are annual or perennial. The leaves are divided into three to ten or more obovate and top-notched leaflets, arranged palmately with all the leaflets of roughly equal size. The majority of species have three ...

Oxalis Acetosella
''Oxalis acetosella'', the wood-sorrel or common wood-sorrel, is a herbaceous rhizome, rhizomatous flowering plant in the family Oxalidaceae. The Botanical name, 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, most of Europe and parts of Asia, it is the only member of its genus and hence simply known as wood-sorrel. While 'common wood-sorrel' may be used to differentiate it from most other species, this name is also used for the North American ''Oxalis montana''. Description The plant grows up to tall. It has trifoliate compound leaves, the leaflets heart-shaped and folded through the middle, that occur in groups of three on the long petioles, and are finely pubescent. The flowers are produced singly on thin, wiry stems from spring to midsummer; they are small, open-faced, with five petals 8–15 mm long, which are white with pink or reddish venation. The flowers ...

Shamrock
A shamrock is a type of clover, used as a symbol of Ireland. 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/yellow clover, Irish: ) or ''Trifolium repens'' (white clover, Irish: ). However, other glossary of leaf morphology#trifoliate, three-leaved plants—such as ''Medicago lupulina'', ''Trifolium pratense'', and ''Oxalis acetosella''—are sometimes called shamrocks. The shamrock was traditionally used for its Herbalism, medicinal properties, and was a popular motif (visual arts), motif in Victorian era, Victorian times. Botanical species There is still not a consensus over the precise Botany, 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 red clover with white flowers. He described the p ...

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 leaf, leaves, 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
Clovers, also called trefoils, are plants of the genus ''Trifolium'' (), consisting of about 300 species of flowering plants in the legume family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with the 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 tall. The leaves are trifoliate (rarely, they have more or fewer than three leaflets; the more (or fewer) leaflets the leaf has, the rarer it is; see four-leaf clover), 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 Calvary clover). As legume ...

Rumex Acetosa
Sorrel (''Rumex acetosa''), also called common sorrel or garden sorrel, is a perennial herbaceous plant in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock ("dock" being a common name for the genus ''Rumex''). Sorrel is native to Eurasia and a common plant in grassland habitats. It is often cultivated as a leaf vegetable or herb. Description Sorrel is a slender herbaceous perennial plant about high, with roots that run deep into the ground, as well as juicy stems and arrow-shaped ( sagittate) leaves which grow from a rosette. The lower leaves are in length with long petioles and a membranous ocrea formed of fused, sheathing stipules. The upper leaves are sessile, (growing directly from the stem without a petiole) and frequently become crimson. It has whorled spikes of reddish-green flowers, which bloom in early summer, becoming purplish. The species is dioecious, with stamens and pistils on different plants. Subspecies Several ...

Bulbil
A bulbil (also referred to as a bulbel, bulblet, and/or pup) is a small, young plant that is reproduced vegetatively from axillary buds on the parent plant's stem or in place of a flower on an inflorescence. These young plants are clones of the parent plant that produced them—they have identical genetic material. The formation of bulbils is a form of asexual reproduction, as they can eventually go on to form new stand-alone plants. Although some bulbils meet the botanical criterion to be considered a true bulb, there are a variety of different morphological forms of bulbils, some of which are not considered to be bulbs. Hence the reason for distinction between bulbs and bulbils. For example, some bulbous plant groups, like onions and lilies, produce bulbils in the form of a secondary, small bulb. Onion and lily bulbils meet the botanical criterion to be labeled a true bulb. All bulbils produced by bulbous plants are to be considered bulbs, but not all bulbils are to be consider ...

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- ...
