Pistache
''Pistacia'' is a genus of flowering plants in the cashew family, Anacardiaceae. It contains 10 to 20 species that are native to Africa and Eurasia from the Canary Islands, all of Africa, and southern Europe, warm and semidesert areas across Asia, and North America from Mexico to warm and semidesert United States, such as Texas or California. Description ''Pistacia'' plants are shrubs and small trees growing to tall. The leaves are alternate, pinnately compound, and can be either evergreen or deciduous depending on species. All species are dioecious, but monoecious individuals of ''Pistacia atlantica'' have been noted. The genus is estimated to be about 80 million years old. It is a genus of flowering plants belonging to the family Anacardiaceae. The plants are dioecious, and have male and female trees independently; a viable population should have both sexes. Well-known species in the genus ''Pistacia'' include ''P. vera'', the pistachio, grown for its edible seeds; '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mastic (plant Resin)
Mastic ( el, Μαστίχα) is a resin obtained from the mastic tree (''Pistacia lentiscus''). It is also known as tears of Chios, being traditionally produced on the island Chios, and, like other natural resins, is produced in "tears" or droplets. Mastic is excreted by the resin glands of certain trees and dries into pieces of brittle, translucent resin. When chewed, the resin softens and becomes a bright white and opaque gum. The flavor is bitter at first, but after some chewing, it releases a refreshing flavor similar to pine and cedar. History Mastic has been harvested for at least 2,500 years since Greek antiquity. The word ''mastic'' is derived from grc-gre, μαστιχάειν, masticháein, 'to gnash the teeth', which is also the source of the English word ''masticate''. The first mention of actual mastic 'tears' was by Hippocrates. Hippocrates used mastic for the prevention of digestive problems, colds and as a breath freshener. Romans used mastic along with honey, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turpentine
Turpentine (which is also called spirit of turpentine, oil of turpentine, terebenthene, terebinthine and (colloquially) turps) is a fluid obtained by the distillation of resin harvested from living trees, mainly pines. Mainly used as a specialized solvent, it is also a source of material for organic syntheses. Turpentine is composed of terpenes, primarily the monoterpenes alpha- and beta-pinene, with lesser amounts of carene, camphene, dipentene, and terpinolene.Kent, James A. ''Riegel's Handbook of Industrial Chemistry'' (Eighth Edition) Van Nostrand Reinhold Company (1983) p.569 Mineral turpentine or other petroleum distillates are used to replace turpentine – although the constituent chemicals are very different. Etymology The word ''turpentine'' derives (via French and Latin), from the Greek word τερεβινθίνη ''terebinthine'', in turn the feminine form (to conform to the feminine gender of the Greek word, which means "resin") of an adjective (τ ...

Pistacia Terebinthus
''Pistacia terebinthus'' also called the terebinth and the turpentine tree, is a deciduous tree species of the genus ''Pistacia'', native to the Mediterranean region from the western regions of Morocco and Portugal to Greece and western and southeastern Turkey. At one time terebinths growing on the eastern shores of the Mediterranean Sea (in Syria, Lebanon and Israel) were regarded as a separate species, ''Pistacia palaestina'', but these are now considered to be a synonym of ''P. terebinthus''. Description The terebinth is a deciduous flowering plant belonging to the cashew family, Anacardiaceae; a small tree or large shrub, it grows to tall. The leaves are compound, long, odd pinnate with five to eleven opposite glossy oval leaflets, the leaflets long and broad. The flowers are reddish-purple, appearing with the new leaves in early spring. The fruit consists of small, globular drupes long, red to black when ripe. All parts of the plant have a strong resinous smell. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistacia Vera
The pistachio (, ''Pistacia vera''), a member of the cashew family, is a small tree originating from Central Asia and the Middle East. The tree produces seeds that are widely consumed as food. ''Pistacia vera'' is often confused with other species in the genus ''Pistacia'' that are also known as pistachio. These other species can be distinguished by their geographic distributions (in the wild) and their seeds which are much smaller and have a soft shell. Etymology Pistachio is from late Middle English ''pistace'', from Old French, superseded in the 16th century by forms from Italian ''pistacchio'', via Latin from Greek ''pistákion'', and from Middle Persian ''pistakē''. History The pistachio tree is native to regions of Central Asia, including present-day Iran and Afghanistan. Archaeology shows that pistachio seeds were a common food as early as 6750 BC. So far, the earliest evidence of pistachio consumption goes back to the Bronze Age Central Asia and comes from Djarkuta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioeci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of ''deciduous'' in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. This process is called ...
