Murraya Paniculata
''Murraya paniculata'', commonly known as orange jasmine, orange jessamine, china box or mock orange, is a species of shrub or small tree in the family Rutaceae and is native to South Asia, Southeast Asia and Australia. It has smooth bark, pinnate leaves with up to seven egg-shaped to elliptical leaflets, fragrant white or cream-coloured flowers and oval, orange-red berries containing hairy seeds. Description ''Murraya paniculata'' is a tree that typically grows to a height of but often flowers and forms fruit as a shrub, and has smooth pale to whitish bark. It has pinnate leaves up to long with up to seven egg-shaped to elliptical or rhombus-shaped. The leaflets are glossy green and glabrous, long and wide on a petiolule long. The flowers are fragrant and are arranged in loose groups, each flower on a pedicel long. There are five (sometimes four) sepals about long and five (sometimes four) white or cream-coloured petals long. Flowering occurs from June to March (i ...

Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus '' Brassica'') and radish (genus '' Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A comp ...

Aurantioideae
Aurantioideae (sometimes known as Citroideae) is the subfamily within the rue and citrus family (Rutaceae) that contains the citrus. The subfamily's center of diversity is in the monsoon region of eastern Australasia, extending west through South Asia into Africa, and eastwards into Polynesia. Notable members include citrus (genus ''Citrus''), bael (''Aegle marmelos''), curd fruit (''Limonia acidissima''), species of genus ''Murraya'' such as curry tree (''M. koenigii'') and orange jessamine (''M. paniculata''), and the small genus ''Clausena''. Description Aurantioideae are smallish trees or large shrubs, or rarely lianas. Their flowers are typically white and fragrant. Their fruit are very characteristic hesperidia, usually of rounded shape and colored in green, yellowish or orange hues. Taxonomy The subfamily has been divided into two tribes, the ancestral Clauseneae and the more advanced Citreae, as in a 1967 classification. A 2021 classification by Appelhans et al. bas ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical f ...

Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Andreas Murray
Johan Andreas (Anders) Murray (27 January 1740 – 22 May 1791) was a Swedish physician of German descent and botanist, who published a major work on plant-derived medicines. Biography Johan Anders Murray was born in Stockholm on 27 January 1740, son of the Prussian-born preacher and theologian Andreas Murray (1695 - 1771). His brothers were the professors Johann Philipp Murray (1726-1776) and Adolph Murray (1751-1803), and the Bishop Gustaf Murray (1747-1825). Murray studied from 1756-1759 in Uppsala, where he was taught by Carl Linnaeus. In 1760, he went to Göttingen, where he became a doctor of medicine in 1763. In 1769, he was appointed professor and director of the botanical garden. He led investigations into the properties of medicinal plants, at that time the main interest of botanists, and into the ways in which plant-derived medicines could be prepared and administered. In 1791, Murray was elected a member of the American Philosophical Society. Murray died in Göttin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Gerhard König
Johann Gerhard König (29 November 1728 – 26 June 1785) was a Baltic German botanist and physician who served in the Tranquebar Mission, India before joining service under the Nawab of Arcot, and then the English East India Company. He collected natural history specimens including plants, particularly those of medical interest, from the region and several species are named after him including the curry tree ''(Murraya'' ''koenigii).'' Biography König was born near ''Kreutzburg'' in Polish Livonia, which is now Krustpils in Latvia. He was a private pupil of Carl Linnaeus in 1757, and lived in Denmark from 1759 to 1767 during which time he examined the plants of Iceland. In 1767 he joined as a medical officer to the Tranquebar Mission and on his voyage to India, he passed through Cape Town where he met Governor Rijk Tulbagh with an introduction from Linnaeus, collecting plants in the Table Mountain region from 1 to 28 April 1768. König replaced the position made available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juice Vesicles
The juice vesicles, also known as citrus kernels, (in aggregate, citrus pulp) of a citrus fruit are the membranous content of the fruit's endocarp. All fruits from the Citranae subtribe, subfamily Aurantioideae, and family Rutaceae have juice vesicles. The vesicles contain the juice of the fruit and appear shiny and sacklike. Vesicles come in two shapes: the superior and inferior, and these are distinct. Citrus fruit with more vesicles generally weighs more than those with fewer vesicles. Fruits with many segments, such as the grapefruit or pomelo, have more vesicles per segment than fruits with fewer segments, such as the kumquat and mandarin. Each vesicle in a segment in citrus fruits has approximately the same shape, size, and weight. About 5% of the weight of an average orange is made up of the membranes of the juice vesicles. Juice vesicles of the endocarp contain the components that provide the aroma typically associated with citrus fruit. These components are also found in ...

Berry (botany)
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible " pericarp". Berries may be formed from one or more carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds. Many berries are edible, but others, such as the fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that bears berries is said to be bacciferous or baccate (a fruit that resembles a berry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
