Polanisia Dodecandra
''Polanisia dodecandra'' is a species of flowering plant in the Cleomaceae family, known by the common name redwhisker clammyweed or clammyweed, and there are three subspecies of ''Polanisia''. Usually annual, occasionally perennial, Polanisia is native to North America, and is found throughout much of Canada and the United States. It favors full sun, mesic to dry conditions, and barren, sandy or gravelly soils, even highly disturbed areas where there is little other ground vegetation. It looks similar to a close relative, the spider flower ('' Cleome''). The scientific name of the genus derives from the fact that the plant has numerous, long stamens of unequal lengths (from Greek ''polys'', "many", and ''anisos'', "unequal"). The name of the species, ''dodecandra'' means "having 12 stamens". The common name clammyweed refers to the sticky, or clammy, residue left on hands after handling the plant. ''Polanisia'' grows from tall and the vegetation and sap have a noticeable odo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polanisia Erosa
''Polanisia erosa'' is a sticky, high annual herbaceous species of flowering plant in the ''Cleome'' family, Cleomaceae, known by the common name large clammyweed. It has narrow clover-like leaves, and cream-coloured, frilly flowers with a yellowish centre, looking a bit like a small butterfly or a set of elk antlers. It naturally occurs in dry and sandy habitats in Texas and adjacent parts of Arkansas, Louisiana and Oklahoma. Taxonomy The American botanist Thomas Nuttall was the first to describe large clammyweed in 1834, which he placed in a new genus and named ''Cristatella erosa''. Amos Eaton included the species in 1836 in the genus ''Cleome'' as ''C. erosa''. In 1842, Stephan Endlicher, an Austrian botanist who was the director of the Vienna Botanical Garden moved the species to a new genus and renamed it to ''Cyrbasium erosum'', which is an illegitimate name. In 1958 Hugh Iltis concluded the species could better be assigned to the genus ''Polanisia'', a name that has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polanisia Jamesii
''Polanisia jamesii,'' common name James's clammyweed, is a plant species native to the central part of the United States.

Cleomaceae
The Cleomaceae are a small family of flowering plants in the order Brassicales, comprising about 300 species in 10 genera, or about 150 species in 17 genera.Cleomaceae, Zhang Mingli (张明理)1; Gordon C. Tucker2, Harvard.edu/ref> These genera were previously included in the family Capparaceae, but were raised to a distinct family when DNA evidence suggested the genera included in it are more closely related to the Brassicaceae than they are to the Capparaceae. The APG II system allows for Cleomaceae to be included in Brassicaceae.Stevens, P. F. (2001 onwards) Angiosperm Phylogeny WebsiteBrassicales Taxonomy In 1994, a group of scientists including Walter Stephen Judd suggested to merge the Capparaceae (which at that time included the Cleomaceae) with the Brassicaceae. Early DNA-analysis showed that the Capparaceae - as defined at that moment - were paraphyletic, and others suggested to assign the genera closest to the Brassicaceae to the Cleomaceae.

Arivela Viscosa
''Cleome'' is a genus of flowering plants in the family Cleomaceae, commonly known as spider flowers, spider plants, spider weeds, or bee plants. Previously, it had been placed in the family Capparaceae, until DNA studies found the Cleomaceae genera to be more closely related to the Brassicaceae than the Capparaceae. Cleome and clammyweed, (''Polanisia dodecandra'') can sometimes be confused. The simplest way to differentiate the two is to compare the seedpods which project out or down on cleome and up on clammyweed. The genus ''sensu stricto'' includes about 170 species of herbaceous annual or perennial plants and shrubs.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening'' 1: 652-653. Macmillan. . The genus has a subcosmopolitan distribution throughout the tropical and warm temperate regions of the world. However, a recent DNA study failed to separate ''Cleome'', ''Podandrogyne'', and ''Polanisia'' from each other, so some taxonomists have abandoned the last two of these ...

Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were rejected automatically by leading journals. Among his theories were th ...

Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an England, English botany, botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle, North Yorkshire, Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury (naturalist), John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens. Nuttall and Bradbury left the party at the trading post with the Arikara Indians in South Dakota, and continued farther upriver with Rams ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minnesota
Minnesota () is a state in the upper midwestern region of the United States. It is the 12th largest U.S. state in area and the 22nd most populous, with over 5.75 million residents. Minnesota is home to western prairies, now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed, and settled; and the less populated North Woods, used for mining, forestry, and recreation. Roughly a third of the state is covered in forests, and it is known as the "Land of 10,000 Lakes" for having over 14,000 bodies of fresh water of at least ten acres. More than 60% of Minnesotans live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", the state's main political, economic, and cultural hub. With a population of about 3.7 million, the Twin Cities is the 16th largest metropolitan area in the U.S. Other minor metropolitan and micropolitan statistical areas in the state include Duluth, Mankato, Moorhead, Rochester, and ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
