Hovenia
''Hovenia'' is a small genus of deciduous trees or shrubs in the family Rhamnaceae. They occur naturally from India to Japan. The Japanese, or Oriental raisin tree, ''Hovenia dulcis'', is the best known species, as it is often planted in gardens outside Asia. Fossil record A fossil wood with features similar to those of the Oligocene ''Hovenia palaeodulcis'' from Japan is described from the late Eocene Florissant Fossil Beds National Monument, Colorado, United States. This is the first report of fossil wood of this Asian genus in North America.A New (Hovenia) and an old (Chadronoxylon) Fossil Wood from the Late Eocene Florissant Formation, Colorado, U.S.A. by Elisabeth Wheeler and Herbert W.

Hovenia Dulcis
''Hovenia dulcis'', or the oriental raisin tree, is a hardy tree found in Asia, from Eastern China ( 萬壽果; pinyin: ) and Korea (, ) to the Himalayas (up to altitudes of 2,000 m), growing preferably in a sunny position on moist sandy or loamy soils. The tree known for its health benefits when consumed in tea, introduced as an ornamental tree to several countries, also bears edible fruit. It is considered to be one of the most pervasive invaders in Brazilian subtropical forests. Description Tree, rarely a shrub, deciduous, to 10–30 m tall. Branchlets brown or black-purple, glabrous, with inconspicuous lenticels. The glossy leaves are large and pointed. The trees bear clusters of small cream-coloured hermaphroditic flowers in July. The drupes appear at the ends of an edible rachis (fleshy fruit stalk), which is a type of accessory fruit. Uses The fleshy rachis of the infructescence is sweet, fragrant and is edible raw or cooked. Dried, they look and taste lik ...

Hovenia Acerba
''Hovenia acerba'' is a species of flowering plant in the raisin tree genus ''Hovenia'' (family Rhamnaceae), native to temperate areas of Nepal, the eastern Himalayas, Assam, Myanmar, northern Thailand, Tibet, and central and southern China. A tree reaching , it is found at elevations up to , in wooded and open areas, forest edges, and slopes, and it is frequently cultivated locally. Like ''Hovenia dulcis'' it is a source of a fine hard timber, and the sweet fruit rachis is edible and is used to make a fruit wine. The seeds are used in traditional medicine. One can distinguish ''Hovenia acerba'' by its fruits, which are yellow or brownish at maturity, whereas those of ''H.dulcis'' are black. It is widely used as a street tree in southern Chinese cities. Subtaxa The following varieties are accepted: *''Hovenia acerba'' var. ''acerba'' – entire range, except Tibet *''Hovenia acerba'' var.

Rhamnaceae
The Rhamnaceae are a large Family (biology), family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales. The family contains about 55 genera and 950 species. The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the Late Cretaceous. Fossil flowers have been collected from the Upper Cretaceous of Mexico and the Paleocene of Argentina. Leaves of family Rhamnaceae members are Simple leaf, simple, i.e., the leaf blades are not divided into smaller leaflets.Flowering Plants of the Santa Monica Mountains, Nancy Dale, 2nd Ed. 2000, p. 166 Leaves can be either alternate or opposite leaves, opposite. Stipules are present and modified into spines in many genera. In some (e.g. ''Paliurus spina-christi'' and ''Colletia paradoxa'') spectacularly so. ''Colletia'' stands out by having two axillary buds i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florissant Fossil Beds National Monument
The Florissant Formation is a sedimentary geologic formation outcropping around Florissant, Teller County, Colorado. The formation is noted for the abundant and exceptionally preserved insect and plant fossils that are found in the mudstones and shales. Based on argon radiometric dating, the formation is Eocene (approximately 34 million years old ) in age and has been interpreted as a lake environment. The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing a diatom bloom. As the diatoms fell to the bottom of the lake, any plants or animals that had recently died were preserved by the diatom falls. Fine layers of clays and muds interspersed with layers of ash form "paper shales" holding beautifully-preserved fossils. The Florissant Fossil Beds National Monument is a national monument established to preserve and study the geology and history of the area. History The name ''Fl ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Sweden, Swedish Natural history, naturalist and an Apostles of Linnaeus, "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Italy and Asia, collecting and describing people and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Carl Linnaeus, Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern Taxonomy (biology), taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to P ...
