Cleome Lutea
''Cleome lutea'' is a species of cleome known by the common names yellow bee plant and yellow spiderflower. This annual wildflower is native to the western United States where it is most common in desert scrub and plateau habitats. It is a sprawling plant often exceeding 1 metre (3 feet) in height. The erect stem can be branched and has widely spaced leaves all the way along, each leaf made up of three to five leaflets, which are smaller closer to the top of the plant. Atop the stem is a showy inflorescence of many bright yellow flowers. Each flower has four narrow sepals and four oblong petals around a cluster of six long stamens tipped with knobby anthers. As the inflorescence lengthens at the top of the stem, flowers that have opened and been pollinated drop their petals and the ovary develops into a fruit. The fruits are capsules several centimeters long containing large seeds; these develop at the base of the inflorescence and hang on pedicels. A flowering plant may have blo ...

William Jackson Hooker
Sir William Jackson Hooker (6 July 178512 August 1865) was an English botanist and botanical illustrator, who became the first director of Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. Hooker was born and educated in Norwich. An inheritance gave him the means to travel and to devote himself to the study of natural history, particularly botany. He published his account of an expedition to Iceland in 1809, even though his notes and specimens were destroyed during his voyage home. He married Maria, the eldest daughter of the Norfolk banker Dawson Turner, in 1815, afterwards living in Halesworth for 11 years, where he established a herbarium that became renowned by botanists at the time. He held the post of Regius Professor of Botany at Glasgow University, where he worked with the botanist and lithographer Thomas Hopkirk and enjoyed the supportive friends ...

Cleome
''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 the ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches. Morphology (biology), Morphologically, it is the modified part of the shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), 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 (botany), 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 (botany) , ... [...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 liv ...

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 '' 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'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynoecium
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are cal ...

Pedicels
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

Plateau Indian
Indigenous peoples of the Northwest Plateau, also referred to by the phrase Indigenous peoples of the Plateau, and historically called the Plateau Indians (though comprising many groups) are indigenous peoples of the Interior of British Columbia, Canada, and the non-coastal regions of the Northwestern United States. Their territories are located in the inland portions of the basins of the Columbia and Fraser Rivers. These tribes mainly live in parts of the Central and Southern Interior of British Columbia, northern Idaho, western Montana, eastern Washington, eastern Oregon, and northeastern California. The eastern flank of the Cascade Range lies within the territory of the Plateau peoples.Pritzker, 249 There are several distinguishing features that differentiate plateau culture from the surrounding native cultures. These include a high reliance on roots, such as biscuitroot and camas, as a food source, a high reliance on short duration salmon and eel runs, and long-ter ...

Common Cold
The common cold or the cold is a viral infectious disease of the upper respiratory tract that primarily affects the respiratory mucosa of the nose, throat, sinuses, and larynx. Signs and symptoms may appear fewer than two days after exposure to the virus. These may include coughing, sore throat, runny nose, sneezing, headache, and fever. People usually recover in seven to ten days, but some symptoms may last up to three weeks. Occasionally, those with other health problems may develop pneumonia. Well over 200 virus strains are implicated in causing the common cold, with rhinoviruses, coronaviruses, adenoviruses and enteroviruses being the most common. They spread through the air during close contact with infected people or indirectly through contact with objects in the environment, followed by transfer to the mouth or nose. Risk factors include going to child care facilities, not sleeping well, and psychological stress. The symptoms are mostly due to the body's i ...
