Acamptopappus Shockleyi
''Acamptopappus shockleyi'', or Shockley's goldenhead, is a perennial subshrub in the family Asteraceae found in and near the eastern Mojave desert in southern Nevada and southeastern California.Mojave Desert Wildflowers, Pam MacKay, 2nd Ed. 2013, p. 183 Description ''Acamptopappus shockleyi'' is a perennial subshrub. Flower heads are borne singly, with both ray flowers and disk flowers, compared to Acamptopappus sphaerocephalus which also grows in the Mojave desert but has only disc flowers on heads in corymbose arrays.Lane, M. A. 1988. Generic relationships and taxonomy of ''Acamptopappus'' (Compositae: Astereae). Madroño 35: 247–265. ''Acamptopappus shockleyi'' grows from in flats and washes of the eastern Mojave Desert, White Mountains, Inyo Mountains The Inyo Mountains are a short mountain range east of the Sierra Nevada in eastern California in the United States.

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 ...

Corymbose
Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are borne on longer pedicels than the inner, bringing all flowers up to a common level. A corymb has a flattish top with a superficial resemblance towards an umbel, and may have a branching structure similar to a panicle. Flowers in a corymb structure can either be parallel, or alternate, and form in either a convex, or flat form. Many species in the Maloideae, such as hawthorns and rowans, produce their flowers in corymbs. The Norway maple and yerba maté are also examples of corymbs. The word ''corymb'' is derived from the Ancient Greek word ''korymbos'' meaning "bunch of flowers or fruit".

Plants Described In 1882
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Natural History Of The Mojave Desert
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Flora Of Nevada
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] |

Astereae
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. They are found primarily in temperate regions of the world. Plants within the tribe are present nearly worldwide divided into over 250 genera and more than 3,100 species, making it the second-largest tribe in the family behind Senecioneae. The taxonomy of the tribe Astereae has been dramatically changed after both morphologic and molecular evidence suggested that large genera such as '' Aster'', as well as many others, needed to be separated into several genera or shifted to better reflect the plants' relationships. A paper by R. D. Noyes and L. H. Rieseberg showed that most of the genera within the tribe in North America actually belong to a single clade, meaning they have a common ancestor. This is referred to as the North American clade. Guy L. Nesom and Harold E. Robinson have been involved in the recent work and are continuing to re-categoris ...

Inyo Mountains
The Inyo Mountains are a short mountain range east of the Sierra Nevada in eastern California in the United States. The range separates the Owens Valley to the west from Saline Valley to the east, extending for approximately south-southeast from the southern end of the White Mountains, from which they are separated by Westgard Pass, to the east of Owens Lake. Geologically, the mountains are a fault block range in the Basin and Range Province, at the western end of the Great Basin. They are considered to be among the most important and best-known Late Proterozoic to Cambrian sections in the United States. Wilderness Most of the mountain range () is designated as the Inyo Mountain Wilderness, managed by the Bureau of Land Management in the south and the United States Forest Service in the north. The USFS manages of the wilderness all within Inyo National Forest. Wildlife in the area includes the endangered Inyo Mountains salamander and the desert bighorn sheep. Plant co ...

White Mountains (California)
The White Mountains of California and Nevada are a triangular fault-block mountain range facing the Sierra Nevada across the upper Owens Valley. They extend for approximately as a greatly elevated plateau about wide on the south, narrowing to a point at the north, with elevations generally increasing south to north. The range's broad southern end is near the community of Big Pine, where Westgard Pass and Deep Springs Valley separate it from the Inyo Mountains. The narrow northern end is at Montgomery Pass, where U.S. Route 6 crosses. The Fish Lake Valley lies east of the range; the southeast part of the mountains are separated from the Silver Peak Range by block faulting across the Furnace Creek Fault Zone, forming a feeder valley to Fish Lake Valley. The range lies within the eastern section of the Inyo National Forest. Ecology Ecologically, the White Mountains are like the other ranges in the Basin and Range Province; they are dry, but the upper slopes from hold open suba ...

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. ...

Disc Flowers
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technically ...

Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
