Calystegia Malacophylla
''Calystegia malacophylla'' is a species of morning glory known by the common name Sierra false bindweed . It is endemic to California, where it grows in several of the mountain ranges, including the Central Coast Ranges and the Sierra Nevada. Description This is a rhizomatous perennial herb with a woolly stem growing to lengths of 10 centimeters to nearly a meter. It generally does not climb as do many other morning glories. The leaves are vaguely kidney-shaped to triangular and pointed, and reach a few centimeters in length. The foliage is covered in a short coat of woolly white hairs, giving the plant a light greenish gray color. The 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 o ... holds a solitary white flower which is sometimes tinted with pink or yellow. The ...

Edward Lee Greene
Edward Lee Greene (August 20, 1843–November 10, 1915) was an American botanist known for his numerous publications including the two-part ''Landmarks of Botanical History'' and the describing of over 4,400 species of plants in the American West. Early life Edward Lee Greene was born on August 20, 1843 in Hopkinton, Rhode Island. In 1859 Greene moved to Wisconsin and began studying at Albion Academy, a very reputable institution with a religious emphasis. There Greene met Thure Kumlien, a Swedish Naturalist with an interest in botany. Greene accompanied Kumlein on field trips, further developing Greene's interest in botany. In August 1862, Greene joined his father and brothers in joining the 13th Wisconsin Volunteer Infantry Regiment of the Union Army. Though he never rose above the rank of private in his three years of service, Greene was able to advance his botanical studies, collecting specimens as he marched through Tennessee, Kentucky and Alabama.

Morning Glory
Morning glory (also written as morning-glory) is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are: * ''Argyreia'' * '' Astripomoea'' * ''Calystegia'' * ''Convolvulus'' * ''Ipomoea'' (the largest genus) * '' Lepistemon'' * ''Merremia'' * ''Operculina'' * '' Rivea'' * ''Stictocardia'' As the name suggests, most ''morning'' glory flowers unfurl into full bloom in the early morning. The flowers usually start to fade a few hours before the corolla begins to display visible curling. They prefer full solar exposure throughout the day, and mesic soils. Some morning glories, such as ''Ipomoea muricata'', ''Ipomoea alba'', and ''Ipomoea macrorhiza'', are night-blooming flowers. History ''Ipomoea nil'', a species of morning glory, was first known in China for its medicinal uses, due to the laxative properties of its seeds. Ancient ...

Endemism
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] |

California Coast Ranges
The Coast Ranges of California span from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains. Physiographically, they are a section of the larger Pacific Border province, which in turn is part of the larger Pacific Mountain System physiographic division. UNESCO has included the "California Coast Ranges Biosphere Reserve" in its Man and the Biosphere Programme of World Network of Biosphere Reserves since 1983. * Physiography The northern end of the California Coast Ranges overlap the southern end of the Klamath Mountains for approximately 80 miles on the west. They extend southward for more than 600 miles to where the coastline turns eastward along the Santa Barbara Channel, around the area of Point Conception. Here the southern end meets the Los Angeles Transverse Ranges, or ''Sierras de los Angeles''. The rocks themselves that com ...

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 ...

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Calystegia
''Calystegia'' (bindweed, false bindweed, or morning glory) is a genus of about 25 species of flowering plants in the bindweed family Convolvulaceae. The genus has a cosmopolitan distribution in temperate and subtropical regions, but with half of the species endemic to California. They are annual or herbaceous perennial twining vines growing 1–5 m tall, with spirally arranged leaves. The flowers are trumpet-shaped, 3–10 cm diameter, white or pink, with (in most species) a sometimes inflated basal epicalyx. The genus bears much similarity to a related genus ''Convolvulus'', and is sometimes combined with it; it is distinguished primarily by the pollen being smooth, and in the ovary being unilocular. Some of the species, notably '' Calystegia sepium'' and '' C. silvatica'', are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers. ''Calystegia'' species are eaten b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Natural History Of The California Coast Ranges
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-So ...
