Stanleya (plant)
''Stanleya'' is a genus of six species of plants in the family Brassicaceae known commonly as prince's plumes. These are herbs or erect shrubs which bear dense, plumelike inflorescences of white to bright yellow flowers with long stamens. ''Stanleya'' species are native to the western United States. These plants are toxic because they concentrate selenium from the soil in their tissues.

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 ...

Brassicaceae
Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). The family contains the cruciferous vegetables, including species such as ''Brassica oleracea'' (cultivated as cabbage, kale, cauliflower, broccoli and collards), ...

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 ...

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'' ...

Selenium
Selenium is a chemical element with the symbol Se and atomic number 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. It seldom occurs in its elemental state or as pure ore compounds in the Earth's crust. Selenium – from Greek ( 'Moon') – was discovered in 1817 by , who noted the similarity of the new element to the previously discovered tellurium (named for the Earth). Selenium is found in metal sulfide ores, where it partially replaces the sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores, most often during production. Minerals that are pure selenide or selenate compounds are known but rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells. Applications in electronics, once important, have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanleya Elata
''Stanleya elata'' is a species of flowering plant in the family Brassicaceae known by the common name Panamint princesplume. It is native to the desert mountains of eastern California and western Nevada, where it grows in rocky and scrubby habitat types. It may also occur in Arizona. It is a perennial herb producing one or more erect stems reaching about 1.5 meters in maximum height. They are hairless and often waxy in texture. The thick, leathery leaves have lance-shaped or oblong blades with smooth or toothed edges measuring up to 15 centimeters long. They are borne on petioles. The top of the stem is occupied by a long inflorescence which is a dense, snaking raceme of many flowers. Each flower has four narrow, threadlike yellow or whitish petals each about a centimeter long and a millimeter wide. The fruit is a long, thin, wormlike silique A silique or siliqua (plural ''siliques'' or ''siliquae'') is a type of fruit (seed capsule) having two fused carpels with the length ...

Stanleya Viridiflora
''Stanleya viridiflora'' is a species of flowering plant in the family Brassicaceae known as green princesplume and green-flowered prince's plume. It is native to the western United States, where it occurs in sagebrush and plateau habitat, often on rocky calcareous, sandstone, clay, shale, or volcanic soils. It is a perennial herb producing a stout erect stem which may exceed a meter in maximum height. It is hairless and sometimes waxy in texture. Its base is a caudex which is generally covered in the remains of withered leaf bases. The leaves have lance-shaped or oblong blades which have smooth or toothed edges or may be divided into a few lobes. The blades may be 22 centimeters long. Some are borne on long petioles, while others, especially those higher on the plant, clasp the stem at their bases. The top of the stem is occupied by a long inflorescence which is an open raceme of many flowers. Each flower bud is enclosed in long, thick sepals which open to reveal yellow or whiti ...

Flora Of The Western United States
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
