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 odor ... [...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 Tenuifolia
''Polansia tenuifolia'' is a species of flowering plant in the family Cleomaceae. It grows in Florida. It is known by the common names pineland catchfly and slender-leaf clammyweed (or slenderleaf clammyweed). It is synonymous with ''Aldenella tenuifolia'', ''Cleome aldanella'', ''Cleome tenuifolia'', and ''Jacksonia tenuifolia''. It is an annual. References Cleomaceae {{Brassicales-stub ...

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 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 genera, treating them as part of ''Cleome'' ''sensu lato''; in this case, ''Cleome'' contains about 275 species, the vast ...

Cleomaceae
The Cleomaceae are a small family of flowering plants in the order Brassicales, comprising about 220 species in two genera, '' Cleome'' and '' Cleomella''. 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 Cleomaceae includes C3, C3–C4, and C4 photosynthesis species. 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.

Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; 22 October 178318 September 1840) was a French early 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 Mound Builders, prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican languages, 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 (person), 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 and his submissions were automati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an English botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near 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, 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 Ramsay Crooks. In August they returned to the Arikara post and jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
