Elaeagnus Rotundata
''Elaeagnus'' () is a genus of flowering plants in the family Elaeagnaceae. Some species of the genus are commonly known as silverberry or oleaster, Description ''Elaeagnus'' plants are deciduous or evergreen shrubs or small trees. The alternate leaves and the shoots are usually covered with tiny silvery to brownish scales, giving the plants a whitish to grey-brown colour from a distance. The flowers are small, with a four-lobed calyx and no petals; they are often fragrant. The fruit is a fleshy drupe containing a single seed; it is edible in many species. Several species are cultivated for their fruit, including ''E. angustifolia'', ''E. umbellata'', and ''E. multiflora'' (gumi). ''E. umbellata'' contains the carotenoid lycopene. Taxonomy The genus ''Elaeagnus'' was erected in 1754 by Carl Linnaeus, who attributed the name to Joseph Pitton de Tournefort. There is agreement that the name is based on Theophrastus's use of the Ancient Greek (, latinized to ) as the name of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Pitton De Tournefort
Joseph Pitton de Tournefort (5 June 165628 December 1708) was a French botanist, notable as the first to make a clear definition of the concept of genus for plants. Botanist Charles Plumier was his pupil and accompanied him on his voyages. Life Tournefort was born in Aix-en-Provence and studied at the Jesuit convent there. It was intended that he enter the Church, but the death of his father allowed him to follow his interest in botany. After two years collecting, he studied medicine at Montpellier, but was appointed professor of botany at the Jardin des Plantes in Paris in 1683. During this time he travelled through Western Europe, particularly the Pyrenees, where he made extensive collections. Between 1700 and 1702 he travelled through the islands of Greece and visited Constantinople, the borders of the Black Sea, Armenia, and Georgia, collecting plants and undertaking other types of observations. He was accompanied by the German botanist Andreas Gundelsheimer (1668� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycopene
Lycopene is an organic compound classified as a tetraterpene and a carotene. Lycopene (from the Neo-Latin '' Lycopersicon'', the name of a former tomato genus) is a bright red carotenoid hydrocarbon found in tomatoes and other red fruits and vegetables. Occurrence Aside from tomatoes or tomato products like ketchup, it is found in watermelons, grapefruits, red guavas, and baked beans. It has no vitamin A activity. In plants, algae, and other photosynthetic organisms, lycopene is an intermediate in the biosynthesis of many carotenoids, including beta-carotene, which is responsible for yellow, orange, or red pigmentation, photosynthesis, and photoprotection. Like all carotenoids, lycopene is a tetraterpene. It is soluble in fat, but insoluble in water. Eleven conjugated double bonds give lycopene its deep red color. Owing to the strong color, lycopene is used as a food coloring (registered as E160d) and is approved for use in the US, Australia and New Zealand (register ...

Elaeagnus Angustifolia
''Elaeagnus angustifolia'', commonly called Russian olive, silver berry, oleaster, or wild olive, is a species of ''Elaeagnus'', native to Asia and limited areas of eastern Europe. It is widely established in North America as an introduced species. Description ''Elaeagnus angustifolia'' is a thorny tree growing to in height. Its stems, buds, and leaves have a dense covering of silvery to rusty scales. The leaves are alternate, lanceolate, long and broad, with a smooth margin. The plants begin to flower and fruit from 3 years old. The highly aromatic flowers, produced in clusters of one to three, are 1 cm long with a four-lobed creamy yellow calyx; they appear in early summer and are followed by clusters of fruit, a small cherry-like drupe long, orange-red covered in silvery scales. The fruits are about 1 cm wide and sweet, though with a dryish, mealy texture. The species is established and reproduced primarily by seed, with some vegetative propagation also occurr ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...
