Arboretum De Grignon
The Arboretum de Grignon (0.8 hectares) is an arboretum located within the campus of the ''Institut des sciences et industries du vivant et de l'environnement'' (Paris Institute of Technology for Life, Food and Environmental Sciences, AgroParisTech) on Avenue Lucien Brétignières, Thiverval-Grignon, Yvelines, Île-de-France (region), Île-de-France, France. It is closed to the public but may be visited by groups. The arboretum was established in 1873 by Pierre Mouillefert, professor at Grignon, who published in 1896 a pamphlet describing the arboretum at that date; however, it was lost in 1940. The arboretum grew gradually over time, with the most recent plantings between 1976-1978. Various of the trees were labeled in 1975 by Mr. George Callen of the Arboretum de Chèvreloup, and in 1991 Mr. Augustin Scalbert created a map identifying almost all trees. At that time, the arboretum contained approximately 230 specimens (66% deciduous, 34% conifers). Unfortunately, the arboretum was ...

Jardin Botanique De L'Institut National
The Jardin botanique de l'Institut National is a small botanical garden located within the campus of the ''Institut des sciences et industries du vivant et de l'environnement'' (AgroParisTech), formerly known as the ''Institut National Agronomique Paris-Grignon'', on the Avenue Lucien Brétignières, Thiverval-Grignon, Yvelines, Île-de-France, France.

Sophora Japonica
''Styphnolobium japonicum'', the Japanese pagoda tree (also known as the Chinese scholar tree and pagoda tree; syn. ''Sophora japonica'') is a species of tree in the subfamily Faboideae of the pea family Fabaceae. It was formerly included within a broader interpretation of the genus ''Sophora''. The species of ''Styphnolobium'' differ from ''Sophora'' in lacking the ability to form symbioses with rhizobia (nitrogen fixing bacteria) on their roots. It also differs from the related genus ''Calia'' (mescalbeans) in having deciduous leaves and flowers in axillary, not terminal, racemes. The leaves are alternate, pinnate, with nine to 21 leaflets, and the flowers in pendulous racemes similar to those of the black locust. Distribution ''Styphnolobium japonicum'' is native to China; despite the name, it was introduced in Japan. It is a popular ornamental tree in Europe, North America and South Africa, grown for its white flowers, borne in late summer after most other flowering trees ...

Pinus Nigra
''Pinus nigra'', the Austrian pine or black pine, is a moderately variable species of pine, occurring across Southern Europe from the Iberian Peninsula to the eastern Mediterranean, on the Anatolian peninsula of Turkey, Corsica and Cyprus, as well as Crimea and in the high mountains of Northwest Africa. Description ''Pinus nigra'' is a large coniferous evergreen tree, growing to high at maturity and spreading to wide. The bark is gray to yellow-brown, and is widely split by flaking fissures into scaly plates, becoming increasingly fissured with age. The leaves ('needles') are thinner and more flexible in western populations. The ovulate and pollen cones appear from May to June. The mature seed cones are (rarely to 11 cm) long, with rounded scales; they ripen from green to pale gray-buff or yellow-buff in September to November, about 18 months after pollination. The seeds are dark gray, long, with a yellow-buff wing long; they are wind-dispersed when the cones open from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parrotia Persica
''Parrotia persica'', the Persian ironwood, is a deciduous tree in the family Hamamelidaceae, closely related to the witch-hazel genus '' Hamamelis''. It is native to Iran's Caspian region (where it is called ) and Iranian Azerbaijan (where it is called '). It is endemic in the Alborz mountains, where it is found mainly in Golestan National Park. The species was named by Carl Anton von Meyer to honor his predecessor at the University of Dorpat, German naturalist Georg Friedrich Parrot., who botanized in the Alborz on a mountaineering expedition in the 1830s. Another species ''Parrotia subaequalis'' (commonly called Chinese ironwood) originates from eastern China. There are five disjunct populations of ''P. subaequalis'' in eastern China: two each in Jiangsu and Zhejiang provinces (Huang et al. 2005) and one in Anhui (Shao and Fang 2004). A full account of this sibling species can be found in an article "The Chinese Parrotia: A Sibling Species of the Persian Parrotia" by Jian ...

Gleditsia Triacanthos
The honey locust (''Gleditsia triacanthos''), also known as the thorny locust or thorny honeylocust, is a deciduous tree in the family Fabaceae, native to central North America where it is mostly found in the moist soil of river valleys. Honey locust is highly adaptable to different environments, has been introduced worldwide, and can be an aggressive, invasive species outside of its native range. Description The honey locust, ''Gleditsia triacanthos'', can reach a height of . They exhibit fast growth, but live a medium life span of about 120 years. The leaves are pinnately compound on older trees but bipinnately compound on vigorous young trees. The leaflets are (smaller on bipinnate leaves) and bright green. They turn yellow in the autumn. Honey locusts leaf out relatively late in spring, but generally slightly earlier than the black locust (''Robinia pseudoacacia''). The strongly scented, cream-colored flowers appear in late spring, in clusters emerging from the base o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ginkgo Biloba
''Ginkgo biloba'', commonly known as ginkgo or gingko ( ), also known as the maidenhair tree, is a species of tree native to China. It is the last living species in the order Ginkgoales, which first appeared over 290 million years ago. Fossils very similar to the living species, belonging to the genus ''Ginkgo'', extend back to the Middle Jurassic approximately 170 million years ago. The tree was cultivated early in human history and remains commonly planted. Ginkgo leaf extract is commonly used as a dietary supplement, but there is no scientific evidence that it supports human health or is effective against any disease. Etymology The genus name is regarded as a misspelling of the Japanese pronunciation ''gin kyo'' for the kanji 銀杏 meaning "silver apricot", which is found in Chinese herbology literature such as (Daily Use Materia Medica) (1329) and ''Compendium of Materia Medica'' published in 1578.T.

A 10-year-old sapling will stand about tall. It has a typical lifespan of 150–200 years, though sometimes up to 300 years. In cultivated forest stands trees are normally harvested at 80–120 years of age. 30 years are needed to attain full maturity (as compared to 40 for American beech). Like most trees, its form depends on the location: in forest areas, ''F. sylvatica'' grows to over , with branches being high up on the trunk. In open locations, it will become much shorter (typically ) and more massive. The leaves are alternate, simple, and entire or with a slightly crenate margin, long and 3–7 cm broad, with 6–7 veins on each side of the leaf (as opposed to 7–10 veins in ...
