Myrtus
''Myrtus'' (commonly called myrtle) is a genus of flowering plants in the family Myrtaceae. It was first described by Swedish botanist Linnaeus in 1753. Over 600 names have been proposed in the genus, but nearly all have either been moved to other genera or been regarded as synonyms. The genus ''Myrtus'' has three species recognised today: *''Myrtus communis'' – Common myrtle; native to the Mediterranean region in southern Europe *''Myrtus nivellei'' – Saharan myrtle; native to North Africa *''Myrtus phyllireaefolia'' Description Common myrtle ''Myrtus communis'', the "common myrtle", is native across the Mediterranean region, Macaronesia, western Asia, and the Indian subcontinent. It is also cultivated. The plant is an evergreen shrub or small tree, growing to tall. The leaf is entire, 3–5 cm long, with a fragrant essential oil. The star-like flower has five petals and sepals, and numerous stamens. Petals usually are white. The flower is pollinated by insec ...

Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...

Myrtus Communis
''Myrtus communis'', the common myrtle or true myrtle, is a species of flowering plant in the myrtle family Myrtaceae. It is an evergreen shrub native to southern Europe, North Africa, Western Asia, Macaronesia, and the Indian Subcontinent, and also cultivated. It is also sometimes known as Corsican pepper. The medicinal properties of ''Myrtus communis'' were utilized as early as 600 B.C.E. Symbolically and ritually important in ancient times, it was used to represent honor, justice, prosperity, generosity, hope, love, and happiness. In Greco-Roman mythology, numerous gods were associated with the common myrtle and its flowers, such as Aphrodite and Demeter. Also a key part of various Jewish traditions, it is one of the four species used in the festival of Sukkot, and the Bible records its use in purification ceremonies. As a shrub that thrives along waterways, it was also seen as a symbol of restoration and recovery. In Europe during the Renaissance, it came to be best known a ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Tuareg Language
The Tuareg () languages constitute a group of closely related Berber languages and dialects. They are spoken by the Tuareg Berbers in large parts of Mali, Niger, Algeria, Libya and Burkina Faso, with a few speakers, the ''Kinnin'', in Chad. Description Tuareg dialects belong to the South Berber group and are sometimes regarded as a single language (as for instance by Karl-Gottfried Prasse). They are distinguished mainly by a few sound shifts (notably affecting the pronunciation of original ''z'' and ''h''). The Tuareg varieties are unusually conservative in some respects; they retain two short vowels where Northern-Berber languages have one or none, and have a much lower proportion of Arabic loanwords than most Berber languages. The Tuareg languages are traditionally written in the indigenous Tifinagh alphabet. However, the Arabic script is commonly used in some areas (and has been since medieval times), while the Latin script is official in Mali and Niger. Subclassification * ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
