Mentzelia Packardiae
''Mentzelia packardiae'' is a species of flowering plant in the Loasaceae known by the common names Packard's blazingstar and Packard's stickleaf. It is native to the western United States, where it is known from a small area in Oregon and Nevada.''Mentzelia packardiae''. Center for Plant Conservation. This annual herb produces erect white to pale green stems up to 40 centimeters tall. The basal leaves are linear and leaves higher on the stem are linear or lance-shaped. Flowers occur along the stem and at its tip. Each has five oval or round petals up to 1.5 centimeters long which are yellow, sometimes with a red spot at the base. The fruit is a capsule up to 3 centimeters long which contains 10 to 20 seeds. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loasaceae
Loasaceae is a family of 15–20 genera and about 200–260 species of flowering plants in the order Cornales, native to the Americas and Africa. Members of the family include annual, biennial and perennial herbaceous plants, and a few shrubs and small trees. Members of the subfamily Loasoideae are known to exhibit rapid thigmonastic stamen movement when pollinators are present. Taxonomy In the classification system of Dahlgren the Loasaceae were placed in the order Loasales in the superorder Loasiflorae (also called Loasanae). The Angiosperm Phylogeny Group system places them in the related order Cornales in the asterid clade. Subdivision Genera include: *''Aosa'' Weigend (sometimes included in ''Loasa'') *''Blumenbachia'' Schrad. *''Caiophora'' C. Presl *''Cevallia'' Lag. *''Chichicaste'' Weigend (sometimes included in ''Loasa'') *''Eucnide'' Zucc. *''Fuertesia'' Urb. *'' Grausa'' Weigend & R.H.Acuña *''Gronovia'' L. *''Huidobria'' Gay (sometimes included in ''Loasa'') ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Volcanic Ash
Volcanic ash consists of fragments of rock, mineral crystals, and volcanic glass, created during volcano, volcanic eruptions and measuring less than 2 mm (0.079 inches) in diameter. The term volcanic ash is also often loosely used to refer to all explosive eruption products (correctly referred to as ''tephra''), including particles larger than 2 mm. Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere. The force of the gases shatters the magma and propels it into the atmosphere where it solidifies into fragments of volcanic rock and glass. Ash is also produced when magma comes into contact with water during phreatomagmatic eruptions, causing the water to explosively flash to steam leading to shattering of magma. Once in the air, ash is transported by wind up to thousands of kilometres away. Due to its wide dispersal, ash can have a number of impacts on society, including animal a ...

Trifolium Owyheense
Clover or trefoil are common names for plants of the genus ''Trifolium'' (from Latin ''tres'' 'three' + ''folium'' 'leaf'), consisting of about 300 species of flowering plants in the legume or pea family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate (rarely quatrefoiled; see four-leaf clover), monofoil, bifoil, cinquefoil, hexafoil, septfoil, etcetera, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include ''Melilotus'' (sweet clover) and '' Medicago'' (alfalfa or Calvary clover ...

Phacelia Lutea
''Phacelia'' (phacelia, scorpionweed, heliotrope) is a genus of about 200 species of annual or perennial herbaceous plants in the borage family, native to North and South America. California is particularly rich in species with over 90 recorded in the region. The genus is traditionally placed at family rank with the waterleafs ( Hydrophyllaceae) in the order Boraginales. The Angiosperm Phylogeny Group, recognizing that the traditional Boraginaceae and Hydrophyllaceae are paraphyletic with respect to each other, merges the latter into the former and considers the family basal in the Euasterids I clade. Other botanists continue to recognize the Hydrophyllaceae and Boraginales after analysing the secondary structure of the ITS1 genetic region rather than its sequence for these higher taxonomic levels. This placed ''Phacelia'' within the Hydrophyllaceae. Further molecular taxonomic analysis of the Boraginales has divided the Boraginales in two and placed ''Phacelia'' among t ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Off-road Vehicle
An off-road vehicle, sometimes referred to as an overland or adventure vehicle, is considered to be any type of vehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension, or even caterpillar tracks. Other vehicles that do not travel on public streets or highways are generally termed off-highway vehicles, including tractors, forklifts, cranes, backhoes, bulldozers, and golf carts. Off-road vehicles have an enthusiastic following because of their versatility. Several types of motorsports involve racing off-road vehicles. The most common use of these vehicles is for sightseeing in areas distant from the pavement. The use of higher clearance and higher traction vehicles enables access on trails and forest roads that have rough and low traction surfaces. Off-road vehicles can typically ford through deeper waters (i.e., rivers or floodwaters) than on-road vehicles can. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
