Charles Vancouver Piper
Charles Vancouver Piper (16 June 1867 – 11 February 1926) was an American botanist and agriculturalist. Born in Victoria, British Columbia, Canada, he spent his youth in Seattle, Washington Territory and graduated from the University of Washington Territory in 1885. He taught botany and zoology in 1892 at the Washington Agricultural College (now Washington State University) in Pullman. He earned a master's degree in botany in 1900 from Harvard University. Piper compiled the first authoritative guides to flora in the northwestern United States. With his collaborator, R. Kent Beattie, he surveyed the Palouse area of southeastern Washington, and expanded the study to the entire state in 1906. That year, The Smithsonian Institution published his catalo''Flora of the State of Washington'' He also publishe''Flora of Southeast Washington and Adjacent Idaho''(1914) an''Flora of the Northwest Coast''(1915). These works established him as an authority on the plants of the northwestern U. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivan Murray Johnston
I. M. (Ivan Murray) Johnston (February 28, 1898–May 31, 1960), was a United States Botany, botanist. He studied at Pomona College in Claremont, California and at Harvard University. His plant collections are housed in the ''Rancho Santa Ana Botanic Garden'', in Claremont, and also in the ''Gray Herbarium'' of Harvard University. His areas of interest, were, among others: Fern, Pteridophytes, Spermatophytes Honours In 1925, German botanist August Brand, named a genus of flowering plants (belonging to the family Boraginaceae), from South America and southern states in USA, as ''Johnstonella'' in his honour. Then in 1933, botanist O.E.Schulz named a genus of flowering plants (belonging to the family Brassicaceae), from Chile as ''Ivania (plant), Ivania''. In 1936, botanist Hsen Hsu Hu published ''Sinojohnstonia'', which is a genus of flowering plants from China, belonging to the family Boraginaceae. Lastly in 1975, another botanist Kazmi, named a monotypic genus of flowering plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boraginaceae
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils ...

Red Fir
''Abies magnifica'', the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States. It is a high-elevation tree, typically occurring at elevation, though only rarely reaching tree line. The name red fir derives from the bark color of old trees. Description ''Abies magnifica'' is a large evergreen tree typically up to tall and trunk diameter, rarely to tall and diameter, with a narrow conic crown. The bark on young trees is smooth, grey, and has resin blisters, becoming orange-red, rough and fissured on old trees. The leaves are needle-like, long, glaucous blue-green above and below with strong stomatal bands, and an acute tip. They are arranged spirally on the shoot, but twisted slightly S-shaped to be upcurved above the shoot. The cones are erect, long, yellow-green (occasionally purple), ripening brown and disintegrating to release the winged seeds in fall. Varieties There are two, pe ...

Lodgepole Pine
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches are covered with short shoots that are easy to remove. ...

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 ...

Flora Of The Sierra Nevada (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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
