Stenocereus
''Stenocereus'' () is a genus of columnar or tree-like cactus, cacti from the Baja California Peninsula and other parts of Mexico, Arizona in the United States, Colombia, Costa Rica, Guatemala, Venezuela and the West Indies. The genus has been enlarged by the addition of species from several other genus, genera. A close relative is the peculiar chinoa or chende cactus, ''Polaskia chende''. Description The species within the genus exhibit varying growth habits, often resembling trees or shrubs. They can also stretch out or creep to form dense thickets, and some species develop well-formed trunks. The green shoots of these plants are cylindrical in shape and feature distinctive cylindrical ribs. From these ribs, woolly areoles are present, from which strong spines emerge. Additionally, some species may have warts, while others do not. The flowers are mostly borne near the wikt:apex, apex of the stems, funnel- or bell-shaped, and mostly nocturnal. The stem that supports the flowers ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stenocereus Thurberi
''Stenocereus thurberi'', the organ pipe cactus, is a species of cactus native to Mexico and the United States. The species is found in rocky desert. Two subspecies are recognized based on their distribution and height. The Organ Pipe Cactus National Monument is named for the species. Cacti are minimally adapted to particular thermal niches, and are tremendously vulnerable to seasonal precipitation. Its English common name is derived from its resemblance to a pipe organ. It is locally known as ''pitaya dulce'', Spanish (language), Spanish for "sweet pitaya" or sweet cactus fruit. Description This cactus species has several narrow stems that rise vertically, growing from a single short trunk just above the ground level.

Dragon Fruit
Pitaya () or pitahaya () (common names strawberry pear or dragon fruit) is the fruit of several cactus species indigenous to the region of southern Mexico and along the Pacific coasts of Guatemala, Costa Rica, and El Salvador. Pitaya is cultivated in East Asia, South Asia, Southeast Asia, the United States, the Caribbean, Australia, Brazil, and throughout tropical and subtropical regions of the world. ''Pitaya'' usually refers to fruit of the genus '' Stenocereus'', while ''pitahaya'' or ''dragon fruit'' refers to fruit of the genus '' Selenicereus'' (formerly ''Hylocereus''), both in the family Cactaceae. The common name in English derives from the leather-like skin and scaly spikes on the fruit exterior, resembling dragon skin. Depending on the variety, pitaya fruits may have sweet- or sour-tasting flesh that can be red, white, or yellow in color. Vernacular names These fruits are commonly known in English as strawberry pear or dragon fruit, a name used since 1963, appar ...

Cactus
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti ...

Wayuu People
The Wayuu (also Wayu, Wayú, Guajiro, Wahiro) are an Indigenous ethnic group of the Guajira Peninsula in northernmost Colombia and northwest Venezuela. The Wayuu language is part of the Arawakan language family. Throughout their history, they have resisted the Spanish, rural land owners, and the Catholic Church. Wayuu tradition remains, and their artisan industry is one of the biggest handicraft exports in present-day Colombia. Geography The Wayuu inhabit the arid Guajira Peninsula straddling the Venezuela-Colombia border, on the Caribbean Sea coast. Two major rivers flow through this mostly harsh environment: the Ranchería River in Colombia and the El Limón River in Venezuela, representing the main sources of water. They're accompanied by artificial ponds designed to hold rainwater during the rain season. The territory has equatorial weather seasons: a rainy season from September to December, which they call ''Juyapu''; a dry season, known by them as ''Jemial'', f ...

Joseph Nelson Rose
Joseph Nelson Rose (January 11, 1862 – May 4, 1928) was an American botanist. He was born in Union County, Indiana. His father died serving during the Civil War when Joseph Rose was a young boy. He later graduated from high school in Liberty, Indiana. He received his Ph.D. in Biology from Wabash College in 1889. having received his B.A. in Biology and M.A. Paleobotany earlier at the same institute. He married Lou Beatrice Sims in 1888 and produced with her three sons and three daughters. Rose worked for the U.S. Department of Agriculture and became an assistant curator at the Smithsonian in 1896. While Rose was employed by the national museum, he was an authority on several plants families, including Apiaceae (Parsley Family) and Cactaceae (Cactus Family). He made several field trips to Mexico, and presented specimens to the Smithsonian and the New York Botanical Garden. With Nathaniel Lord Britton, Rose published many articles on the Crassulaceae. He took a leave of abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wattle And Daub
Wattle and daub is a composite material, composite building method in which a woven lattice of wooden strips called "wattle (construction), wattle" is "daubed" with a sticky material usually made of some combination of wet soil, clay, sand, and straw. Wattle and daub has been used for at least 6,000 years and is still an important construction method in many parts of the world. Many historic buildings include wattle and daub construction. History The wattle and daub technique has been used since the Neolithic period. It was common for houses of Linear pottery culture, Linear pottery and Rössen cultures of middle Europe, but is also found in Western Asia (Çatalhöyük, Shillourokambos) as well as in North America (Mississippian culture) and South America (Brazil). In Africa it is common in the architecture of traditional houses such as those of the Ashanti people. Its usage dates back at least 6,000 years. There are suggestions that construction techniques such as lath and pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Plant
Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost all types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents, aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and ''foliage plants''. The cultivation of ornamental plants comes under floriculture and tree nurseries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
