Delphinium Bakeri
''Delphinium bakeri'', or Baker's larkspur, is a species of perennial herb in the buttercup family, Ranunculaceae. It is endemic to California in the United States, where it is a federally listed endangered species. It is known in the wild from one remaining occurrence near Salmon Creek in Sonoma County, where only seven plants remained . ''D. bakeri'' grows from a thickened, tuber-like, fleshy cluster of roots, to a height of . The leaves occur primarily along the upper third of the stem and are green at the time the plant flowers. The flowers are irregularly shaped. It has five conspicuous sepals, bright dark blue or purplish, with the rear sepal elongated into a spur. The inconspicuous petals occur in two pairs. The lower pair is oblong and blue-purple, the upper pair oblique and white. Seeds are produced in several dry, many-seeded fruits that split open at maturity on only one side. The species flowers from April through May. Baker's larkspur grows on decomposed shale wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial Plant
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 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Natural History Of The California Chaparral And Woodlands
Nature, in the broadest sense, is the physics, physical world or universe. "Nature" can refer to the phenomenon, 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 ...

Endemic Flora Of California
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delphinium
''Delphinium'' is a genus of about 300 species of annual and perennial flowering plants in the family (biology), family Ranunculaceae, native plant, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus. All members of the genus ''Delphinium'' are toxic to humans and livestock. The common name larkspur is shared between perennial ''Delphinium'' species and annual species of the genus ''Consolida''. Molecular data show that ''Consolida'', as well as another segregate genus, ''Aconitella'', are both embedded in ''Delphinium''. The genus name ''Delphinium'' derives from the Ancient Greek word () which means "dolphin", a name used in ''De Materia Medica'' for some kind of larkspur. Pedanius Dioscorides said the plant got its name because of its dolphin-shaped flowers. Habitat Species with short stems and few flowers such as ''Delphinium nuttallianum'' and ''Delphinium bicolor'' appear in habitats like p ...

Milo Samuel Baker
Milo Samuel Baker (July 19, 1868 – January 4, 1961) was an American botanist, specializing in plants of the northern coastal region of California, as well as the genus ''Viola''. In 1875 Milo Samuel Baker moved with his family to Tehama County, California. After graduating from secondary school in San Jose, he became a school teacher in Santa Clara County and Modoc County. He studied from 1891 to 1892 at Stanford University. He graduated from the University of California, Berkeley with a bachelor's degree in chemistry in 1895. He taught from 1901 to 1906 at San Francisco's Lowell High School. After working as a farmer and rancher in Kenwood, he was a professor of botany from 1922 to 1945 at Santa Rosa Junior College (SRJC). He established the North Coast Herbarium at SRJC and in 1933 donated his private collection to the Herbarium. In retirement, he continued to tend the Herbarium and at SRJC continued to teach the introductory field botany course until he was over 90. Baker ...

Backhoe
A backhoe—also called rear actor or back actor—is a type of excavating equipment, or digger, consisting of a digging bucket on the end of a two-part articulated arm. It is typically mounted on the back of a tractor or front loader, the latter forming a "backhoe loader" (a US term, but known as a " JCB" in Ireland and the UK). The section of the arm closest to the vehicle is known as the boom, while the section that carries the bucket is known as the dipper (or dipper-stick), both terms derived from steam shovels. The boom is generally attached to the vehicle through a pivot known as the king-post, which allows the arm to pivot left and right, usually through a total of 180 to 200 degrees. Description The term "backhoe" refers to the action of the bucket, not its location on the vehicle. That is, a backhoe digs by drawing earth backwards, rather than lifting it with a forward motion like a person shovelling, a steam shovel, or a bulldozer. The buckets on some backhoes may ...

Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management, nature reserves, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introduced as ornamental plants for horticultural use. Some "noxious weeds", such as ragwort, produce copious amou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", whic ...

Point Reyes Peninsula
Point Reyes (, meaning "Point of the Kings") is a prominent cape and popular Northern California tourist destination on the Pacific coast. Located in Marin County, it is approximately west-northwest of San Francisco. The term is often applied to the Point Reyes Peninsula, the region bounded by Tomales Bay on the northeast and Bolinas Lagoon on the southeast. The headland is protected as part of Point Reyes National Seashore. Overview The cape protects Drakes Bay on its southern side. The headland is largely drained by Drakes Estero. Drakes Bay and Drake's Estero are named after English seafarer Sir Francis Drake who possibly hauled his ship, the ''Golden Hinde'', up onto the beach for repairs in June 1579. Inverness Ridge runs along the peninsula's northwest-southeast spine, with forested peaks around . West of the ridge, the land flattens out and the vegetation turns to scrub. The Mount Vision fire in 1995 burned part of Inverness Ridge. Point Reyes lends its name to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
