Private Property
Private property is a legal designation for the ownership of property by non-governmental legal entities. Private property is distinguishable from public property and personal property, which is owned by a state entity, and from collective or cooperative property, which is owned by a group of non-governmental entities. Private property is foundational to capitalism, an economic system based on the private ownership of the means of production and their operation for profit. The distinction between private and personal property varies depending on political philosophy, with socialist perspectives making a hard distinction between the two. As a legal concept, private property is defined and enforced by a country's political system. History Ideas about and discussion of private property date back to the Persian Empire, and emerge in the Western tradition at least as far back as Plato. Prior to the 18th century, English speakers generally used the word "property" in reference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Witch-hazel
Witch-hazels or witch hazels (''Hamamelis'') are a genus of flowering plants in the family Hamamelidaceae, with three species in North America ('' H. ovalis'', '' H. virginiana'', and '' H. vernalis''), and one each in Japan ('' H. japonica'') and China ('' H. mollis''). The North American species are occasionally called winterbloom. Growth The witch-hazels are deciduous shrubs or (rarely) small trees growing to 3 to 7.5 m tall, even more rarely to 12 m tall. The leaves are alternately arranged, oval, 5 to 15 cm long, and 2.5 to 10 cm wide, with a smooth or wavy margin. The genus name, ''Hamamelis'', means "together with fruit", referring to the simultaneous occurrence of flowers with the maturing fruit from the previous year. ''H. virginiana'' blooms in September–November while the other species bloom from January–March. Each flower has four slender strap-shaped petals 1 to 2 cm long, pale to dark yellow, orange, or red. The fruit is a two-part capsule ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allegheny Blackberry
''Rubus allegheniensis'' is a North American species of glandular highbush blackberry in section Alleghenienses of the genus ''Rubus'', a member of the rose family. It is the most common and widespread highbush blackberry in eastern and central North America. It is commonly known as Allegheny blackberry. Description The characteristics of ''Rubus allegheniensis'' can be highly variable. It is an erect bramble, typically but occasionally rarely over high, with single shrubs approaching 2.4 m or more in breadth, although it usually forms dense thickets of many plants. The leaves are alternate, compound, ovoid, and have toothed edges. Canes have many prickles, with white, 5-petal, flowers in late spring and glossy, deep-violet to black, aggregate fruit in late summer. It is shade intolerant.Peterson, Chris J., and Steward T.A.

Striped Maple
''Acer pensylvanicum'', known as the striped maple, moosewood, moose maple or goosefoot maple, is a small North American species of maple. The striped maple is a sequential hermaphrodite, meaning that it can change its sex throughout its lifetime. Description The striped maple is a small deciduous tree growing to tall, with a trunk up to in diameter. The shape of the tree is broadly columnar, with a short, forked trunk that divides into arching branches which create an uneven, flat-topped crown. The young bark is striped with green and white, and when a little older, brown. The leaves are broad and soft, long and broad, with three shallow forward-pointing lobes. The fruit is a samara; the seeds are about long and broad, with a wing angle of 145° and a conspicuously veined pedicel. The bloom period for Acer pensylvanicum is around late spring. The spelling ''pensylvanicum'' is the one originally used by Linnaeus. Small, finger-diameter sections of branches can be use ...

Red Maple
''Acer rubrum'', the red maple, also known as swamp maple, water maple, or soft maple, is one of the most common and widespread deciduous trees of eastern and central North America. The U.S. Forest Service recognizes it as the most abundant native tree in eastern North America. The red maple ranges from southeastern Manitoba around the Lake of the Woods on the border with Ontario and Minnesota, east to Newfoundland, south to Florida, and southwest to East Texas. Many of its features, especially its leaves, are quite variable in form. At maturity, it often attains a height around . Its flowers, petioles, twigs, and seeds are all red to varying degrees. Among these features, however, it is best known for its brilliant deep scarlet foliage in autumn. Over most of its range, red maple is adaptable to a very wide range of site conditions, perhaps more so than any other tree in eastern North America. It can be found growing in swamps, on poor, dry soils, and almost anywhere in between. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arisaema Triphyllum
''Arisaema triphyllum'', the jack-in-the-pulpit, bog onion, brown dragon or Indian turnip, is a herbaceous perennial plant growing from a corm. It is a highly variable species typically growing in height with three-part leaves and flowers contained in a spadix that is covered by a hood. It is native to eastern North America, occurring in moist woodlands and thickets from Nova Scotia west to Minnesota, and south to southern Florida and Texas. Description The leaves are trifoliate, with groups of three leaves growing together at the top of one long stem produced from a corm; each leaflet is long and broad. Plants are sometimes confused with poison-ivy especially before the flowers appear or non-flowering plants. The inflorescences are shaped irregularly and grow to a length of up to 8 cm. They are greenish-yellow or sometimes fully green with purple or brownish stripes. The spathe, known in this plant as "the pulpit" wraps around and covers over and contain a spadi ...

Symplocarpus Foetidus
''Symplocarpus foetidus'', commonly known as skunk cabbage or eastern skunk cabbage (also swamp cabbage, clumpfoot cabbage, or meadow cabbage, foetid pothos or polecat weed), is a low growing plant that grows in wetlands and moist hill slopes of eastern North America. Bruised leaves present an odor reminiscent of skunk. ''Symplocarpus'' combines the Greek word ''symploce'', meaning "connection" and ''carpos'', meaning "fruit", to indicate that the plant has a compound fruit. The genus name ''Symplocarpus'' combines two Greek words: ''Symplo-'' is derived from υμπλoκή meaning connection, ''-carpus'' is derived from αρπòς meaning fruit. Linnaeus gave the plant its species name of ''foetidus,'' Latin for "bad-smelling". The plant produces a strong odor, which is repulsive to many but sometimes described as smelling like "fresh cabbage with a slight suggestion of mustard". The odor increases in intensity over time, as the plant matures, likely due to increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aralia Nudicaulis
''Aralia nudicaulis'' (commonly wild sarsaparilla,Dickinson, T.; Metsger, G.; Hull, J.; and Dickinson, R. (2004) The ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 140. false sarsaparilla, shot bush, small spikenard, wild liquorice, and rabbit root) is a flowering plant of northern and eastern North America which reaches a height of with creeping underground stems. Description In the spring the underground stems produce compound leaves that are large and finely toothed. Tiny white flowers, typically in three, globe-shaped clusters wide, are produced on tall scapes that grow about the same height as the leaves. These bloom from May to July and develop into purple-black edible berries. The leaves go dormant in summer before the fruits ripen. The berries taste a little spicy and sweet. The stem of the plant grows straight up from the ground and divides into a whorl of 3 stems which branch up and out, each forming 3 to 7 (most often 5) pinnately com ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
