Anemone Multifida
''Anemone multifida'' is a species of flowering plant in the buttercup family known by the common names cutleaf anemone, Pacific anemone and globe anemone. It is a perennial herb native to northern North America from Alaska to New York and as far south as Arizona and New Mexico. It is also known from parts of South America. Description This is a perennial herb which is quite variable in appearance, especially across varieties. It grows from a branching caudex to heights from 10 to 70 centimeters. The long petioled leaves are covered in a coat of long silky or coarse white hairs. Each leaf is divided into many long, pointed lobes, and the lobes are sometimes subdivided. Including the petiole a single leaf may be 5 to 20 centimeters long. The basal leaves are divided two or three times into narrow segments. The inflorescence holds one or more flowers. The flowers have no petals but four to eight (usually five) petallike sepals which may be nearly any color but typically white. The ...

Pulsatilla Patens
''Pulsatilla patens'' is a species of flowering plant in the family Ranunculaceae, native to Europe, Russia, Mongolia, and China. Common names include Eastern pasqueflower and cutleaf anemone. Taxonomy It was first formally named in 1753 as ''Anemone patens'' and is sometimes still considered part of that genus. The species ''Pulsatilla nuttalliana'', the pasqueflower native to much of North America, it is sometimes considered a subspecies or variety of ''Pulsatilla patens''. Two subspecies are accepted: * ''Pulsatilla patens'' subsp. ''patens'' * ''Pulsatilla patens'' subsp. ''multifida'' Cultural associations ''Pulsatilla patens'' is the regional flower of the region of Tavastia Proper in Finland Finland ( fi, Suomi ; sv, Finland ), officially the Republic of Finland (; ), is a Nordic country in Northern Europe.

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Anemone
''Anemone'' () is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all continents except Australia, New Zealand and Antarctica. The genus is closely related to several other genera including ''Anemonoides'', ''Anemonastrum'', ''Hepatica'', and ''Pulsatilla''. Some botanists include these genera within ''Anemone''. Description ''Anemone'' are perennials that have basal leaves with long leaf-stems that can be upright or prostrate. Leaves are simple or compound with lobed, parted, or undivided leaf blades. The leaf margins are toothed or entire. Flowers with 4–27 sepals are produced singly, in cymes of 2–9 flowers, or in umbels, above a cluster of leaf- or sepal-like bracts. Sepals may be any color. The pistils have one ovule. The flowers have nectaries, but petals are missing in the majority of species. The fruits are ovoid to obovoid shaped ...

Great Lakes Region
The Great Lakes region of North America is a binational Canadian–American region that includes portions of the eight U.S. states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin along with the Canadian province of Ontario. Quebec is at times included as part of the region because, although it is not in a Great Lake watershed, it encompasses most of the St. Lawrence River watershed, part of a continuous hydrologic system that includes the Great Lakes. The region centers on the Great Lakes and forms a distinctive historical, economic, and cultural identity. A portion of the region also encompasses the Great Lakes Megalopolis. Participating state and provincial governments are represented in the Conference of Great Lakes and St. Lawrence Governors and Premiers, which also serves as the Secretariat to the Great Lakes St. Lawrence Compact and the Great Lakes–Saint Lawrence River Basin Sustainable Water Resources Agreement.

Boreal Plains Ecozone (CEC)
The Boreal Plains Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a terrestrial Ecozones of Canada, ecozone in the western Canada, Canadian provinces of Manitoba, Saskatchewan and Alberta. It also has minor extensions into northeastern British Columbia and south-central Northwest Territories. The region extends over 779,471 km2, of which 58,981 km2 is conserved (7.6 percent). Wood Buffalo National Park, the largest national park in Canada, and Whooping Crane Summer Range, the only nesting and breeding area for the critically endangered whooping crane, are both located in the northern portion of this ecozone. Industry in this ecozone once consisted primarily of forestry and agriculture, but in 1967 Great Canadian Oil Sands, Great Canadian Oil Sands Limited began extracting bitumen from the Athabasca oil sands. Operations there have expanded significantly since 2003, and the oil sands are becoming an increasingly significant economic factor in ...

Subarctic
The subarctic zone is a region in the Northern Hemisphere immediately south of the true Arctic, north of humid continental regions and covering much of Alaska, Canada, Iceland, the north of Scandinavia, Siberia, and the Cairngorms. Generally, subarctic regions fall between 50°N and 70°N latitude, depending on local climates. Precipitation is usually low, and vegetation is characteristic of the taiga. Daylight at these latitudes is quite extreme between summer and winter due to its high latitude. Near the summer solstice for instance, subarctic regions can experience an all-night period of either civil, nautical, or astronomical twilight (or in the northern reaches full daylight), but without true night, since the sun never dips more than 18 degrees below the horizon. Noctilucent clouds are best observed within this range of latitude. Climate and soils Subarctic temperatures are above for at least one and at most three months of the year. Precipitation tends to be low du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utah
Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin. Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute. The Spanish were the first Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Jean Louis Marie Poiret
Jean Louis Marie Poiret (11 June 1755 in Saint-Quentin7 April 1834 in Paris) was a French clergyman, botanist, and explorer. From 1785 to 1786, he was sent by Louis XVI to Algeria to study the flora. After the French Revolution, he became a professor of natural history at the Écoles Centrale of Aisne. The genus '' Poiretia'' of the legume family Fabaceae was named after him in 1807 by Étienne Pierre Ventenat.

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 ...
