Alfred Rehder
Alfred Rehder (4 September 1863 in Waldenburg, Saxony – 25 July 1949 in Jamaica Plain, Massachusetts) was a German-American botanical taxonomist and dendrologist who worked at the Arnold Arboretum of Harvard University. He is generally regarded as the foremost dendrologist of his generation. Life Georg Alfred Rehder was born in the castle of Waldenburg to Thekla née Schmidt (1839–1897) and Paul Julius Rehder (1833–1917), the superintendent of parks and gardens of the principality of Schönburg-Waldenburg. Through his father, Rehder was introduced to the gardening profession. On his mother's side of the family, Rehder was likely descended from Henry, Duke of Anhalt-Köthen (1778–1847). Rehder broke off his attendance at the gymnasium in Zwickau in 1881 and did not pursue university studies, instead working for three years as an apprentice under the tutelage of his father. His professional career began in 1884 at the Berlin Botanical Garden. Here he was able to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vine
A vine (Latin ''vīnea'' "grapevine", "vineyard", from ''vīnum'' "wine") is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Daydon (1928). ''A Glossary of Botanic Terms with their Derivation and Accent'', 4th ed. London: Gerald Duckworth & Co. In parts of the world, including the British Isles, the term "vine" usually applies exclusively to grapevines (''Vitis''), while the term "climber" is used for all climbing plants. Growth forms Certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available. A vine displays a growth form based on very long stems. This has two purposes. A vine may use rock exposures, other plants, or other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parthenocissus
''Parthenocissus'' , is a genus of tendril vine, climbing plants in the grape family (biology), family, Vitaceae. It contains about 12 species native plant, native to the Himalayas, eastern Asia and North America. Several are grown for ornamental use, notably ''P. henryana'', ''P. quinquefolia'' and ''P. tricuspidata''. Etymology The name derives from the Greek ''parthenos'', "virgin", and ''kissos'' (Latinized as "cissus"), "ivy". The reason is variously given as the ability of these creepers to form seeds without pollen, pollination or the English name of ''P. quinquefolia'', Virginia creeper, which has become attached to the whole genus. Fossil record Among the middle Miocene Sarmatian (age), Sarmatian palynology, palynoflora from the Lavanttal Basin Austria, Austrian researchers have recognized ''Parthenocissus'' fossil pollen. The sediment containing the ''Parthenocissus'' fossil pollen had accumulated in a lowland wetland environment with various vegetation units of mixed ...
