Eastern Prairie Fringed Orchid
''Platanthera leucophaea'', commonly known as the prairie white fringed orchid or eastern prairie fringed orchid, is a rare species of orchid native to North America. It is listed as a threatened species in the United States on September 28, 1989. The IUCN does not currently recognize it as being at risk. Distribution ''Platanthera leucophaea'' is found in moist to wet tallgrass prairie, sedge meadows, fens, and old fields. For optimum growth, little or no woody encroachment should be near the habitat. Historically, the eastern prairie fringed orchid is found primarily in the Great Lakes Region with isolated populations in Maine, Virginia, Iowa, and Missouri. A historic record exists for Choctaw County, Oklahoma. The plant has not been observed in Oklahoma in the past 150 years. The major factor in the decline of the eastern prairie fringed orchid has been a loss of habitat due to grazing, fire suppression, and agricultural conversion.

Iowa
Iowa () is a state in the Midwestern region of the United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River to the west. It is bordered by six states: Wisconsin to the northeast, Illinois to the east and southeast, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north. During the 18th and early 19th centuries, Iowa was a part of French Louisiana and Spanish Louisiana; its state flag is patterned after the flag of France. After the Louisiana Purchase, people laid the foundation for an agriculture-based economy in the heart of the Corn Belt. In the latter half of the 20th century, Iowa's agricultural economy transitioned to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production. Iowa is the 26th most extensive in total area and the 31st most populous of the 50 U.S. states, with a populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Platanthera
The genus ''Platanthera'' belongs to the subfamily Orchidoideae of the family Orchidaceae, and comprises about 150 species of orchids. The members of this genus, known as the butterfly orchids or fringed orchids, were previously included in the genus ''Orchis'', which is a close relative (along with the genus ''Habenaria''). They are distributed throughout the temperate regions of the Northern Hemisphere. They are terrestrial and have tubercules. Etymology Louis Claude Richard chose the name ''Platanthera'' for this genus; it comes from the Greek and means "broad or wide anther," referring to the separation of the base of the pollinia in the type species of the genus. Richard felt that this characteristic distinguished the genus ''Platanthera'' from both the genus ''Orchis'' and the genus ''Habenaria''. However, today the defining characteristics of the genus are generally accepted to be the absence of both stigmatic processes (typical in ''Habenaria'') and ovoid root-tuberoi ...

Sphinx Moths
The Sphingidae are a family of moths (Lepidoptera) called sphinx moths, also colloquially known as hawk moths, with many of their caterpillars known as “hornworms”; it includes about 1,450 species. It is best represented in the tropics, but species are found in every region.Scoble, Malcolm J. (1995): ''The Lepidoptera: Form, Function and Diversity'' (2nd edition). Oxford University Press & Natural History Museum London. They are moderate to large in size and are distinguished among moths for their agile and sustained flying ability, similar enough to that of hummingbirds as to be reliably mistaken for them. Their narrow wings and streamlined abdomens are adaptations for rapid flight. The family was named by French zoologist Pierre André Latreille in 1802. Some hawk moths, such as the hummingbird hawk-moth or the white-lined sphinx, hover in midair while they feed on nectar from flowers, so are sometimes mistaken for hummingbirds. This hovering capability is only known to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's Intensity (heat transfer), intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platanthera Praeclara
''Platanthera praeclara'', known as the western prairie fringed orchid and the Great Plains white fringed orchid, is a rare and threatened species of orchid native to North America. Distribution Historically, ''Platanthera praeclara'' was found in tallgrass prairies west of the Mississippi River. It occurred from extreme southern Canada south to northeast Oklahoma. In Oklahoma, historical records (1975) exist for Craig and Rogers Counties. Currently, extant populations of the orchid are found in Iowa, Kansas, Manitoba, Minnesota, Missouri, Nebraska, and North Dakota. Description ''Platanthera praeclara'' arises from a fleshy tuber. It grows from tall. Each plant can have up to two dozen or more flowers arranged in a stalk. ''P. praeclara'' is distinguished from ''Platanthera leucophaea'', the eastern prairie fringed orchid, by its slightly larger flowers, petal shape, and longer nectar spur. ''Platanthera praeclara'' is a long-lived perennial. It emerges in May and blooms in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Tuber
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typical stems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
