Cleomella Parviflora
''Cleomella parviflora'' is a species of flowering plant in the cleome family known by the common name slender stinkweed. It is native to eastern California and western Nevada, where it grows in desert and sagebrush scrub in the Mojave Desert and southern parts of the Great Basin. It is an annual herb producing a smooth, hairless, reddish stem up to about 45 centimeters tall. There are a few leaves, each made up of three elongated, fleshy leaflets. Most of the flowers are located in a raceme A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers.

Each flower has four tiny pale yellow petals, each about 2 millimeters long. The fruit is a lobed, valved capsule which hangs on the tip of th ...

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

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. The Cleomaceae and Brassicac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sagebrush
Sagebrush is the common name of several woody and herbaceous species of plants in the genus ''Artemisia''. The best known sagebrush is the shrub ''Artemisia tridentata''. Sagebrushes are native to the North American west. Following is an alphabetical list of common names for various species of the genus ''Artemisia'', along with their corresponding scientific name. Many of these species are known by more than one common name, and some common names represent more than one species. * Alpine sagebrush—' * African sagebrush—''Artemisia afra'' * Basin sagebrush—''Artemisia tridentata'' * Big sagebrush—see Basin sagebrush * Bigelow sagebrush—''Artemisia bigelovii'' * Birdfoot sagebrush—'' Artemisia pedatifida'' * Black sagebrush—''Artemisia nova'' * Blue sagebrush—see Basin sagebrush * Boreal sagebrush—'' Artemisia norvegica'' * Budsage—''Artemisia spinescens'' * California sagebrush—''Artemisia californica'' * Carruth's sagebrush—'' Artemisia carruthii'' * C ...

Mojave Desert
The Mojave Desert ( ; mov, Hayikwiir Mat'aar; es, Desierto de Mojave) is a desert in the rain shadow of the Sierra Nevada mountains in the Southwestern United States. It is named for the indigenous Mojave people. It is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah. The Mojave Desert, together with the Sonoran, Chihuahuan, and Great Basin deserts, forms a larger North American Desert. Of these, the Mojave is the smallest and driest. The Mojave Desert displays typical basin and range topography, generally having a pattern of a series of parallel mountain ranges and valleys. It is also the site of Death Valley, which is the lowest elevation in North America. The Mojave Desert is often colloquially called the "high desert", as most of it lies between . It supports a diversity of flora and fauna. The desert supports a number of human activities, including recreation, ranching, and military training. ...

Great Basin
The Great Basin is the largest area of contiguous endorheic basin, endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physical geography, physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrography, hydrographic, ecology, biological, floristic province, floristic, physiographic, topography, topographic, and Ethnography, ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature o ...

Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Cleomella
''Cleomella'' is a small genus of about ten species of flowering plants. Like their relatives, the cleomes, plants of this genus have traditionally been included in the caper family Capparaceae but have recently been moved into a new family, Cleomaceae. ''Cleomella'' are annual wildflowers native to the dry and desert regions of western North America. They are similar to cleomes in appearance. They are erect and branching with leaves divided into three leaflets and inflorescences of yellow flowers with long 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 filame ...s. ''Cleomella'' species are known commonly as stinkweeds or simply cleomellas. Species include: *'' Cleomella angustifolia'' - narrowleaf rhombopod *'' Cleomella arborea'' - bladderpod *'' Cleomella brevipes'' - shortstal ...

Flora Of California
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] |
