Oleaceae Genera
Oleaceae, also known as the olive family or sometimes the lilac family, is a Taxonomy (biology), taxonomic family (biology), family of flowering plant, flowering shrubs, trees, and a few lianas in the Order (biology), order Lamiales. It presently comprises 28 genera, one of which is recently extinct.Peter S. Green. 2004. "Oleaceae". pages 296-306. In: Klaus Kubitzki (editor) and Joachim W. Kadereit (volume editor). ''The Families and Genera of Vascular Plants'' volume VII. Springer-Verlag: Berlin; Heidelberg, Germany. The extant genus, genera include ''Cartrema'', which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous.Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. . The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive
The olive, botanical name ''Olea europaea'' ("European olive"), is a species of Subtropics, subtropical evergreen tree in the Family (biology), family Oleaceae. Originating in Anatolia, Asia Minor, it is abundant throughout the Mediterranean Basin, with wild subspecies in Africa and western Asia; modern Cultivar, cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar. The olive is the type species for its genus, ''Olea'', and lends its name to the Oleaceae plant family, which includes species such as Syringa vulgaris, lilac, jasmine, forsythia, and Fraxinus, ash. The olive fruit is classed botanically as a drupe, similar to the cherry or peach. The term oil—now used to describe any Viscosity, viscous Hydrophobe, water-insoluble liquid—was virtually synonymous with olive oil, the Vegetable oil, liquid fat made from olives. The olive has deep historical, economic, and cultural significance in the Mediterranean; Georges Duhamel (author), George ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Polyphyletic
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. [Source for pronunciation.] It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthesis, C4 photosynthetic plants, and Xenarthra#Evolutionary relationships, edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major re ...

Anthony Huxley
Anthony Julian Huxley (2 December 1920 – 26 December 1992) was a British botanist and writer. An elected council member of the Royal Horticultural Society, he became its vice president in 1991. He edited '' Amateur Gardening'' from 1967 to 1971, and ''Royal Horticultural Society Dictionary of Gardening'' from 1988 to 1992. Biography Huxley was the elder son of Julian Huxley and Juliette (''née'' Baillot). His brother Francis became an anthropologist. Born at the time when his father was a Fellow at New College, Oxford, and a Senior Demonstrator of zoology, he grew up in Oxford. As his father became professor of zoology at King's College London, in 1925, he spent the rest of his childhood in London. He was educated at Dauntsey's School and Trinity College, Cambridge. After graduation, he worked in the Royal Air Force and the Ministry of Aircraft Production for 10 years as a flight technician ( boffin). After a brief service in the British Overseas Airways Corporation, he work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syringa Vulgaris
''Syringa vulgaris'', the lilac or common lilac, is a species of flowering plant in the olive family, Oleaceae. Native to the Balkan Peninsula, it is widely cultivated for its scented flowers in Europe (particularly the north and west) and North America. Description ''Syringa vulgaris'' is a large deciduous shrub or multi-stemmed small tree, growing to high. It produces secondary shoots from the base or roots, with stem diameters up to , which in the course of decades may produce a small clonal thicket. The bark is grey to grey-brown, smooth on young stems, longitudinally furrowed, and flaking on older stems. The leaves are simple, and 3–8 cm broad, light green to glaucous, oval to cordate, with pinnate leaf venation, a mucronate apex, and an entire margin. They are arranged in opposite pairs or occasionally in whorls of three. The flowers have a tubular base to the corolla 6–10 mm long with an open four-lobed apex 5–8 mm across, usually lilac to mauv ...

Chionanthus
''Chionanthus'' (), common name: fringetrees, is a genus of about 140 species of flowering plants in the family Oleaceae. The genus has a wide distribution primarily in the tropics and subtropics, but with three species extending north into temperate regions, one (''C. retusus'') in eastern Asia and two (''C. virginicus'' and ''C. henryae'') in eastern North America. Most of the tropical species are evergreen, while the three temperate species are deciduous. Some botanists restrict ''Chionanthus'' to the deciduous, temperate species, treating the evergreen species in a separate genus ''Linociera'', but apart from leaf persistence, there is no other consistent difference between them. They are shrubs and small to medium-sized trees growing to 3–25 m tall. The leaves are opposite, simple. The flowers are produced in feathery panicles, with a corolla subdivided into four slender lobes; they are white, pale yellow, or tinged pink. The fruit is a drupe containing a single seed. ...

Forsythia
''Forsythia'' , is a genus of flowering plants in the olive family Oleaceae. There are about 11 species, mostly native to Eastern Asia, but one native to Southeastern Europe. ''Forsythia'' – also one of the plant's common names – is named after the botanist William Forsyth. Description ''Forsythia'' are deciduous shrubs typically growing to a height of and, rarely, up to with rough grey-brown bark. The leaves are borne oppositely and are usually simple, though sometimes trifoliate with a basal pair of small leaflets; they range between in length and, rarely, up to , with a margin that is serrated or entire (smooth). Twigs may be hollow or chambered, depending on the species. The flowers are produced in the early spring before the leaves, bright yellow with a deeply four-lobed corolla, the petals joined only at the base. These become pendent in rainy weather thus shielding the reproductive parts. The fruit is a dry capsule, containing several winged seeds. There is a ...

Privet
A privet is a flowering plant in the genus ''Ligustrum''. The genus contains about 50 species of erect, deciduous or evergreen shrubs or trees, with a native distribution from Europe to tropical and subtropical Asia, and with one species each native to Australia and north Africa. Some species have become widely naturalized or invasive where introduced. ''Privet'' was originally the name for the European semi-evergreen shrub '' Ligustrum vulgare'', and later also for the more reliably evergreen '' Ligustrum ovalifolium'' and its hybrid '' Ligustrum × ibolium'' used extensively for privacy hedging, though now the name is applied to all members of the genus. The generic name was applied by Pliny the Elder (23–79 AD) to ''L. vulgare''. It is often suggested that the name ''privet'' is related to ''private'', but the Oxford English Dictionary states that there is no evidence to support this. Description Privet is a group of shrubs and small trees of southern and eastern Asia, fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Plant
Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost all types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents, aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and ''foliage plants''. The cultivation of ornamental plants comes under floriculture and tree nurseries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jasmine
Jasmine (botanical name: ''Jasminum'', pronounced ) is a genus of shrubs and vines in the olive family of Oleaceae. It contains around 200 species native to tropical and warm temperate regions of Eurasia, Africa, and Oceania. Jasmines are widely cultivated for the characteristic fragrance of their flowers. The village of Shubra Beloula in Egypt grows most of the jasmine used by the global perfume industry. Description Jasmine can be either deciduous or evergreen, and can be erect, spreading, or climbing shrubs and vines. The leaves are borne in opposing or alternating arrangement and can be of simple, trifoliate, or pinnate formation. The flowers are typically around in diameter. They are white or yellow, although in rare instances they can be slightly reddish. The flowers are borne in cymose clusters with a minimum of three flowers, though they can also be solitary on the ends of branchlets. Each flower has about four to nine petals, two locules, and one to four ovu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraxinus
''Fraxinus'' (), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some Subtropics, subtropical species are evergreen trees. The genus is widespread throughout much of Europe, Asia, and North America. The leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness; if grown as an ornamental and both sexes are present, ashes ...
