Pinus Orizabensis
''Pinus orizabensis'', the Orizaba pinyon, is a pine in the pinyon pine group, endemic to central Mexico. It is considered also as a sub-species of ''Pinus cembroides'' which is classified as ''Pinus cembroides'' subsp. ''orizabensis'' D.K.Bailey. It has larger seeds than the type. The range is localised, confined to a small area in the eastern Eje Volcánico Transversal range (Trans-Mexican Volcanic Belt), in the states of Puebla and Veracruz. It occurs at high altitudes, mostly from , in a cooler, moister climate than the other pinyon pines. Description It is a small to medium-size tree, reaching tall and with a trunk diameter of up to 50 cm. The bark is dark brown, thick and deeply fissured at the base of the trunk. The leaves ('needles') are in mixed fascicles of three and four, slender, 3–6 cm long, and deep green to blue-green, with stomata confined to a bright white band on the inner surfaces. Cones The cones are globose to ovoid, 4–7 cm long and 3†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Pico De Orizaba
Pico de Orizaba, also known as Citlaltépetl (from Nahuatl = star, and = mountain), is an inactive stratovolcano, the highest mountain in Mexico and the third highest in North America, after Denali of Alaska in the United States and Mount Logan of Canada. Pico de Orizaba is also the highest volcanic summit in North America. It rises above sea level in the eastern end of the Trans-Mexican Volcanic Belt, on the border between the states of Veracruz and Puebla. The volcano is currently dormant but not extinct, with the last eruption taking place during the 19th century. It is the second most prominent volcanic peak in the world after Africa's Mount Kilimanjaro. Toponymy Pico de Orizaba overlooks the valley and city of Orizaba, from which it gets its Spanish name. During the colonial era, the volcano was also known as Cerro de San Andrés due to the nearby settlement of San Andrés Chalchicomula at its base. Its Náhuatl name, Citlaltépetl, comes from ''citlalli'' (star) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Mexico
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] |

Pine Nut
Pine nuts, also called piñón (), pinoli (), pignoli or chilgoza (), are the edible seeds of pines (family Pinaceae, genus ''Pinus''). According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also edible, but are too small to be of notable value as a human food. Species and geographic spread In Asia, two species in particular are widely harvested: Korean pine (''Pinus koraiensis'') in northeast Asia (the most important species in international trade) and chilgoza pine (''Pinus gerardiana'') in the western Himalaya. Four other species, Siberian pine (''Pinus sibirica''), Siberian dwarf pine (''Pinus pumila''), Chinese white pine (''Pinus armandii'') and lacebark pine (''Pinus bungeana''), are also used to a lesser extent. Russia is the largest producer of ''Pinus sibirica'' nuts in the world, followed b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden
A garden is a planned space, usually outdoors, set aside for the cultivation, display, and enjoyment of plants and other forms of nature. The single feature identifying even the wildest wild garden is ''control''. The garden can incorporate both natural and artificial materials. Gardens often have design features including statuary, follies, pergolas, trellises, stumperies, dry creek beds, and water features such as fountains, ponds (with or without fish), waterfalls or creeks. Some gardens are for ornamental purposes only, while others also produce food crops, sometimes in separate areas, or sometimes intermixed with the ornamental plants. Food-producing gardens are distinguished from farms by their smaller scale, more labor-intensive methods, and their purpose (enjoyment of a hobby or self-sustenance rather than producing for sale, as in a market garden). Flower gardens combine plants of different heights, colors, textures, and fragrances to create interest and delight the s ...

Park
A park is an area of natural, semi-natural or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. Urban parks are urban green space, green spaces set aside for recreation inside towns and cities. National parks and country parks are green spaces used for recreation in the countryside. State parks and provincial parks are administered by sub-national government states and agencies. Parks may consist of grassy areas, rocks, soil and trees, but may also contain buildings and other artifacts such as monuments, fountains or playground structures. Many parks have fields for playing sports such as baseball and football, and paved areas for games such as basketball. Many parks have trails for walking, biking and other activities. Some parks are built adjacent to bodies of water or watercourses and may comprise a beach or boat dock area. Urban parks often have benches for sitting and may contain picnic tables and barbecue gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potosi Pinyon
''Pinus culminicola'', commonly known as Potosà pinyon or Potosà Piñón, is a pine in the pinyon pine group, native and endemism, endemic to northeast Mexico. The range is highly localised, confined to a small area of high summits in the northern Sierra Madre Oriental in Coahuila and Nuevo León, and only abundant on the highest peak, Cerro Potosà (3713 m). It occurs at very high altitudes, from 3000–3700 m, in cool, moist subalpine climate conditions. Description It is a medium-size shrub, reaching 1.5–5 m tall and with a trunk diameter of up to 25 cm.

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
