Spiranthes Bightensis
''Spiranthes bightensis'', the Atlantic ladies tresses, is a terrestrial orchid native to coasts of the north-eastern United States. Description ''Spiranthes bightensis'' plants look similar to ''Spiranthes cernua'' and '' Spiranthes odorata''. They are tall (up to 100 cm), with 1-5 basal leaves present at flowering time, and wider than those of ''Spiranthes cernua''. The white flowers are arranged in a spiral around the stem. ''Spiranthes bightensis'' flowers are usually fragrant, while ''Spiranthes cernua'' ones are not. Distribution and habitat ''Spiranthes bightensis'' is endemic to the eastern US Mid-Atlantic shoreline and the New York Bight The New York Bight is the geological identification applied to a roughly triangular indentation, regarded as a bight, along the Atlantic coast of the United States that extends northeasterly from Cape May Inlet in New Jersey to Montauk Point on .... The species name ''bightensis'' derives from this ''bight''. It occurs in De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrestrial Plant
A terrestrial plant is a plant that grows on, in, or from land. Other types of plants are aquatic (living in water), epiphytic (living on trees) and lithophytic (living in or on rocks). The distinction between aquatic and terrestrial plants is often blurred because many terrestrial plants are able to tolerate periodic submersion and many aquatic species have both submersed and emersed forms. There are relatively few obligate submersed aquatic plants (species that cannot tolerate emersion for even relatively short periods), but some examples include members of Hydrocharitaceae and Cabombaceae, ''Ceratophyllum'', and ''Aldrovanda'', and most macroalgae (e.g. '' Chara'' and ''Nitella''). Most aquatic plants can, or prefer to, grow in the emersed form, and most only flower in that form. Many terrestrial plants can tolerate extended periods of inundation, and this is often part of the natural habitat of the plant where flooding is common. These plants (termed helophytes) tolerate ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiranthes Cernua
''Spiranthes cernua'', commonly called nodding lady's tresses, or nodding ladies' tresses, is a species of orchid occurring from Maritime Canada to the eastern and southern United States. As the common name suggests ''cernua'' means "nodding", or "bowed" in Latin. Description ''Spiranthes cernua'' plants grow to tall. They have 1 to 5 narrow, basal, upright leaves, long and wide. The leaves are present during flowering but wilt afterwards. The white flowers are arranged in a spiral around the stem. Each flower is long and consists of 3 sepals and 3 petals, all curved forward to give the flower a long bell shape. Flowers are slightly to strongly nodding (hence the name), with older flowers usually nodding more than new ones. The dorsal sepal (the one at the top) is convex and recurved upwards towards the tip. The lip (bottom petal) curves strongly downwards towards its tip. Etymology The genus name, Spiranthes, originated from the Greek words speira (coil) and anthos (flower ...

Spiranthes Odorata
''Spiranthes odorata'', marsh lady's tresses or common lady's tresses, is a species of flowering plant in the orchid family, native to the southeastern United States, from Texas eastwards and northwards to Delaware. It grows in moist, partially shaded environments with acidic or neutral soil. An herbaceous perennial, this orchid grows up to tall and broad. The flowers are borne in dense vertical rows on sturdy green spikes, in a slightly twisted pattern (hence ''Spiranthes'', "twisted flower"). This effect is due to uneven cell growth. The flowers, which appear in late summer and autumn, are white, hooded and fragrant (hence the specific epithet ''odorata''). This plant is pollinated by bumblebees, notably '' Bombus pensylvanicus'', '' Bombus fervidus'', '' Bombus impatiens'', and ''Bombus nevadensis''. In the UK, the cultivar ‘Chadd’s Ford’ has gained the Royal Horticultural Society’s Award of Garden Merit. Requiring a fertile soil in partial shade, it is hardy dow ...

New York Bight
The New York Bight is the geological identification applied to a roughly triangular indentation, regarded as a bight, along the Atlantic coast of the United States that extends northeasterly from Cape May Inlet in New Jersey to Montauk Point on the eastern tip of Long Island. As the result of direct contact with the Gulf Stream along the coast of North America, the coastal climate of the bight area is temperate. Geography The bight is formed by the roughly right-angled intersection of the generally north-south Atlantic coast of New Jersey and the approximately east–west southern coast of Long Island at the mouth of the Hudson River. The New York Bight Apex is the area including and between the Hudson River estuary and the Raritan River estuary extending 6–7 km of the coast, and it includes Raritan Bay and the Lower New York Bay. Weather The geography of the bight has long been of major concern to meteorologists in the study of tropical storm patterns along the easte ...

Swale (landform)
A swale is a shady spot, or a sunken or marshy place. In US usage in particular, it is a shallow channel with gently sloping sides. Such a swale may be either natural or human-made. Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration. Bioswales are swales that involve the inclusion of plants or vegetation in their construction, specifically. On land This swale concept has also been popularized as a rainwater harvesting Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir ... and soil conservation strategy by Bill Mollison, David Holmgren, and other advocates of permaculture. In this context it is usually a water-harvesting ditch on contour, also called a ''contour Bunding, bund''. Swales as used in ...

Sphagnum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuges, ericaceous shrubs, as well as orchids and carnivorous plant ...

Spiranthes
''Spiranthes'' is a genus of orchids in the subfamily Orchidoideae. They are known commonly as ladies tresses, ladies'-tresses, or lady's tresses.''Spiranthes''. Integrated Taxonomic Information System (ITIS). The genus is distributed in the Americas, Eurasia, and Australia.''Spiranthes''. Flora of North America.

Orchids Of The United States
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
