Spiranthes Sylvatica
''Spiranthes sylvatica'', the woodland ladies' tresses or pale-green ladies'-tresses is a terrestrial orchid endemic to the United States, very similar in appearance and range to '' Spiranthes praecox'' which it had been considered a variation of for a long time. Description ''Spiranthes sylvatica'' plants are a species of tall spiranthes, up to 80 cm high with up to 7 basal leaves. There are 10-30 greenish white flowers arranged in a spiral around the stem. Just like in ''Spiranthes praecox'' the lip of each flower has prominent dark green veins. Besides the more greenish flower color another difference of ''Spiranthes sylvatica'' to ''Spiranthes praecox'' is a larger flower size, 10-17 mm as opposed to 6-9 mm. Bloom time is March to June. Distribution and habitat ''Spiranthes sylvatica'' is native to Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, Texas and Virginia. It grows in dry forests near the coast such as in live oak ... [...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 Praecox
''Spiranthes praecox'', the grass leaved ladies' tresses (sometimes spelled grassleaf ladies'-tresses), green-vein ladies'-tresses or sometimes giant ladies' tresses is a terrestrial orchid endemic to the United States, growing on the eastern coastal plains and around the Gulf Coast. Description ''Spiranthes praecox'' is a herbaceous species growing 20–75 cm high, with up to 7 long basal leaves. There are up to 40 white flowers arranged in a spiral around the stem. The lip of each flower has prominent, branched green colored veins. Bloom time is mainly from February to June (or even later at the northern range extent). Form ''Spiranthes praecox forma albolabia'' has pure white lips with yellowish instead of green veins. Distribution and habitat ''Spiranthes praecox'' is native to Alabama, Arkansas, Delaware, Florida, Georgia, Louisiana, Maryland, Mississippi, Missouri, New Jersey, North Carolina, Oklahoma, South Carolina, Texas, Virginia. It grows in coastal planes in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Live Oak
Live oak or evergreen oak is any of a number of oaks in several different sections of the genus ''Quercus'' that share the characteristic of evergreen foliage. These oaks are not more closely related to each other than they are to other oaks. The name ''live oak'' comes from the fact that evergreen oaks remain green and "live" throughout winter, when other oaks are dormant and leafless. The name is used mainly in North America, where evergreen oaks are widespread in warmer areas along the Atlantic coast from southeast Virginia to Florida, west along the Gulf Coast to Louisiana and Mexico, and across the southwest to California. Evergreen oak species are also common in parts of southern Europe and south Asia, and are included in this list for the sake of completeness. These species, although not having "live" in their common names in their countries of origin, are colloquially called live oaks when cultivated in North America. When the term live oak is used in a specific rathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hammock (ecology)
Hammock is a term used in the southeastern United States for stands of trees, usually hardwood, that form an ecological island in a contrasting ecosystem. Hammocks grow on elevated areas, often just a few inches high, surrounded by wetlands that are too wet to support them. The term ''hammock'' is also applied to stands of hardwood trees growing on slopes between wetlands and drier uplands supporting a mixed or coniferous forest. Types of hammocks found in the United States include tropical hardwood hammocks, temperate hardwood hammocks, and maritime or coastal hammocks. Hammocks are also often classified as hydric (wet soil), mesic (moist soil) or xeric (dry soil). The types are not exclusive, but often grade into each other. Unlike many ecosystems of the coastal plain of the southeastern United States, hammocks are not tolerant of fire. Hammocks tend to occur in locations where fire is not common, or where there is some protection from fire in neighboring ecosystems. Hammocks ...

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] |
