Friedrich Gottlob Hayne
Friedrich Gottlob Hayne (18 March 1763, Jüterbog – 24 April 1832, Berlin) was a German botanist, taxonomist, pharmacist and professor. Hayne showed an early interest in the plant world. From 1778 until 1796 he worked as a pharmacist in Berlin, and was acquainted with the botanist Carl Ludwig Willdenow of about the same age, who at the time was also a pharmacist in Berlin. From 1797 he worked on botanical and technical commissions for the factories department of the Prussian government. From 1801 to 1808 he worked in Schönebeck on the Elbe, where he was an assistant in the "Royal Prussian Chemical Factory" (later named 'Hermania'), which was founded in 1793 by pharmacist Carl Hermann Samuel and was the first German chemical factory. During his stay in Schönebeck he studied the chemical composition of plants and collected the flora of the region. After the Treaty of Tilsit in 1807, the Kingdom of Prussia lost about half of its territory, including all territory west of the El ...

Hymenaea
''Hymenaea'' is a genus of plants in the legume family Fabaceae. Of the fourteen living species in the genus, all but one are native to the tropics of the Americas, with one additional species (''Hymenaea verrucosa'') on the east coast of Africa. Some authors place the African species in a separate monotypic genus, ''Trachylobium''.Gwilym Lewis, Brian Schrire, Barbara MacKinder, and Mike Lock. 2005. ''Legumes of the World''. Royal Botanic Gardens, Kew: Richmond, England. In the Neotropics, ''Hymenaea'' is distributed through the Caribbean islands, and from southern Mexico to Brazil. Linnaeus named the genus in 1753 in ''Species Plantarum'' for Hymenaios, the Greek god of marriage ceremonies. The name is a reference to the paired leaflets. Most species of ''Hymenaea'' are large trees and they are primarily evergreen. They may grow to a height of and emerge above the forest canopy. Some species will grow both as tall forest trees and as smaller shrubby trees depending on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astilbin
Astilbin is a flavanonol, a type of flavonoid. Astilbin is the (2R-trans)-isomer; neoisoastilbin is the (2S-cis)-isomer and isoastilbin is the (2R-cis)-isomer. Natural occurrences Astilbin can be found in St John's wort (''Hypericum perforatum'', Clusiaceae, subfamily Hypericoideae, formerly often considered a full family Hypericaceae), in '' Dimorphandra mollis'' (Fava d'anta, Fabaceae), in the leaves of ''Harungana madagascariensis'' (Hypericaceae), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trees Of Brazil
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
