American Liberty (elm Cultivar)
The American elm cultivar ''Ulmus americana'' 'American Liberty' is in fact a group of six genetically distinct cultivars under a single name, although they are superficially similar.Townsend, A. M., Bentz, S. E., and Douglass L. W. (2005)Evaluation of 19 American Elm Clones for Tolerance to Dutch Elm Disease.''Journal of Environmental Horticulture'', March 2005, Horticultural Research Institute, Washington, D.C. The Liberty elm is reportedly suitable for street planting, being tolerant of de-icing salts and air pollution. However, examples included in 10-year trials at Atherton, California to evaluate replacements for Californian elms lost to disease did not perform well. The late Professor Eugene Smalley summarized 'American Liberty' as "not as resistant as the Asian hybrids, but it still has the look of a classic American Elm". Description Generally similar to the species. Pests and diseases The six clones which comprise this series vary considerably in their level of resis ...

Ulmus Americana
''Ulmus americana'', generally known as the American elm or, less commonly, as the white elm or water elm, is a species of elm native to eastern North America, naturally occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 ° C (−44 ° F). Trees in areas unaffected by Dutch elm disease (DED) can live for several hundred years. A prime example of the species was the Sauble Elm, which grew beside the banks of the Sauble River in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to DED; when it was felled in 1968, a tree-ring count established that it had germinated in 1701. For over 80 years, ''U. americana'' had been identified as a tetraploid, i.e. having double the usual number of chromosomes, making it unique within the genus. However, a study published in 2011 by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scott Arboretum
Scott Arboretum () is an arboretum coterminous with the campus of and operated by Swarthmore College. It is open to the public daily without charge. The arboretum was established and endowed by the Scott family in 1929 in honor of Arthur Hoyt Scott (class of 1895, inventor of the paper towel), "for the purpose of enabling Swarthmore College to acquire, cultivate and propagate the better kinds of living trees, shrubs and herbaceous plants which are hardy in the climate of eastern Pennsylvania and which are suitable for planting by the average gardener." Today the arboretum contains over 4,000 kinds of ornamental plants, labeled with scientific and common names, and grouped in collections for ready comparison. It is "celebrated for its horticultural excellence and display" and "grants Swarthmore’s 1,500 students an academic life immersed in the plant kingdom, although the arboretum welcomes visitors as well." Each year, the Scott Outdoor Amphitheater plays host to the commenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australasia
Australasia is a region that comprises Australia, New Zealand and some neighbouring islands in the Pacific Ocean. The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different, but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific (Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colonies) and New Zealand. Australasia found continued geopolitical attention in the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
