A cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1,750 known species of the order Caryophyllales. The word cactus derives, through Latin, from the Ancient Greek word κάκτος (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 where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of true leaves, cacti's enlarged stems carry out photosynthesis.
In musical instrument classification, string instruments or chordophones, are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae, not just to members of the genus.
An idiophone is any musical instrument that creates sound primarily by the vibration of the instrument itself, without the use of air flow, strings (chordophones), membranes (membranophones) or electricity (electrophones). It is the first of the four main divisions in the original Hornbostel–Sachs system of musical instrument classification. The early classification of Victor-Charles Mahillon called this group of instruments autophones. The most common are struck idiophones, or concussion idiophones, which are made to vibrate by being struck, either directly with a stick or hand or indirectly, with scraping or shaking motions. Various types of bells fall into both categories. A common plucked idiophone is the Jew's harp.
A percussion mallet or beater is an object used to strike or beat a percussion instrument in order to produce its sound.
Cylindropuntia imbricata, the cane cholla, is a cactus found in the Southwestern United States and northern Mexico, including some cooler regions in comparison to many other cacti. It occurs primarily in the arid regions of the Southwestern United States in the states of Kansas, Oklahoma, Texas, New Mexico, Arizona, Colorado, and Nevada. It is often conspicuous because of its shrubby or even tree-like size, its silhouette, and its long-lasting yellowish fruits.
Turbinicarpus is a genus of very small to medium-sized cacti, which inhabit the north-eastern regions of Mexico, in particular the states of San Luis Potosí, Guanajuato, Nuevo León, Querétaro, Hidalgo, Coahuila, Tamaulipas and Zacatecas.
Parodia is a genus of flowering plants in the family Cactaceae, native to the eastern slopes of the Andes in northwestern Argentina and southwestern Bolivia and in the lowland pampas regions of northeastern Argentina, southern Brazil, eastern Paraguay, and Uruguay. This genus has about 65 species, many of which have been transferred from Eriocactus, Notocactus and Wigginsia. They range from small globose plants to 1 m (3 ft) tall columnar cacti. All are deeply ribbed and spiny, with single flowers at or near the crown. Some species produce offsets at the base. They are popular in cultivation, but must be grown indoors where temperatures fall below 10 °C (50 °F).
The word shaker describes various percussive musical instruments used for creating rhythm in music.
The güira is a percussion instrument from the Dominican Republic used as a percussion instrument in merengue, bachata, and to a lesser extent, other genres such as cumbia. It is made of a metal sheet and played with a stiff brush, thus being similar to the Haitian graj and the Cuban guayo and güiro. Güira, guayo and güiro all have a function akin to that of the indigenous native maracas or the trap-kit's hi-hat, namely providing a complementary beat.
Hand percussion is a percussion instrument that is held in the hand. They can be made from wood, metal or plastic, bottles stops and are usually shaken, scraped, or tapped with fingers or a stick. It includes all instruments that are not drums or pitched percussion instruments such as the marimba or the xylophone.
The kashaka is a simple percussion instrument consisting of two small gourds filled with beans One gourd is held in the hand and the other is quickly swung from side to side around the hand, creating a "clack" sound upon impact. It originated in West Africa, but has been reproduced in various countries under different names: Patica (Japan), Kosika (USA). Other names include Asalato, Kes Kes, Tchangot Tche, Koshkah, and many others.
Cereus repandus, the Peruvian apple cactus, is a large, erect, spiny columnar cactus found in South America. It is also known as giant club cactus, hedge cactus, cadushi, and kayush.
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word succulent comes from the Latin word sucus, meaning "juice" or "sap".
In plant morphology, thorns, spines, and prickles, and in general spinose structures, are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
Rhipsalidopsis gaertneri, synonyms Schlumbergera gaertneri and Hatiora gaertneri, is a species of epiphytic cactus which belongs to the tribe Rhipsalideae within the subfamily Cactoideae of the Cactaceae. Together with the hybrid with R. rosea, Rhipsalidopsis × graeseri, it is known, in English speaking countries in the Northern Hemisphere, as Easter cactus or Whitsun cactus and is a widely cultivated ornamental plant. It has received the Royal Horticultural Society's Award of Garden Merit.
Flora of the Sonoran Desert includes six subdivisions based on vegetation types. Two are north of the boundary between the United States and Mexico, and four are south of the boundary. The flora of the Colorado Desert are influenced by the environment of the very dry and hot lower areas of the Colorado River valley, which may be barren, treeless, and generally have no large cacti. Flora of the Arizona Upland are comparatively lush, with trees and large columnar cacti that can withstand winter frosts. Those subdivisions of the Sonoran Desert which lie south of the international border are characterized by plants that cannot withstand frost.
The tube zither is a stringed musical instrument in which a tube functions both as an instrument's neck and its soundbox. As the neck, it holds strings taut and allows them to vibrate. As a soundbox, it modifies the sound and transfers it to the open air. The instruments are among the oldest of chordophones, being "a very early stage" in the development of chordophones, and predate some of the oldest chordophones, such as the Chinese Se, zithers built on a tube split in half. Most tube zithers are made of bamboo, played today in Madagascar, India, Southeast Asia and Taiwan. Tube zithers made from other materials have been found in Europe and the United States, made from materials such as cornstalks and cactus.
The acitrón is a Mexican candy which is commonly used as a decoration on a three kings' cake. As an ingredient, it has great cultural significance since it is used in a large number of ritual and festive preparations. Unfortunately, the biznaga cactus from which acitróns are made is an endangered species due to excessive consumption.
