cactus plant meaning

By the early 20th century, botanists came to feel Linnaeus's name Cactus had become so confused as to its meaning (was it the genus or the family?) Definitions by the largest Idiom Dictionary. [66], Cacti were cultivated as ornamental plants from the time they were first brought from the New World. They are mainly found in the coastal mountains and Atlantic forests of southeastern Brazil; in Bolivia, which is the center of diversity for the subfamily Rhipsalideae; and in forested regions of Central America, where the climbing Hylocereeae are most diverse. Ex situ conservation aims to preserve plants and seeds outside their natural habitats, often with the intention of later reintroduction. [22] CAM-cycling is a less efficient system whereby stomata open in the day, just as in plants using the C3 mechanism. Plants using the C3 mechanism lose as much as 97% of the water taken up through their roots in this way. Cochineal is the product of an insect that lives on some cacti. Because transpiration takes place during the cooler, more humid night hours, water loss is significantly reduced. Some cacti have taproots; in genera such as Copiapoa, these are considerably larger and of a greater volume than the body. Stems needed to develop structures similar to those normally found only in leaves. [10] A mature saguaro (Carnegiea gigantea) is said to be able to absorb as much as 200 U.S. gallons (760 l; 170 imp gal) of water during a rainstorm. Their areoles identify them as cacti, and in spite of their appearance, they, too, have many adaptations for water conservation. Cactus - Idioms by The Free Dictionary ... Hummingbirds, bats and insects eat the nectar of cactus flowers, while pollinating the plants in return. [17] A key issue in retaining water is the ratio of surface area to volume. Fungicides may be of limited value in combating these diseases. Lust and sexual attraction between two people; The power and loneliness of the desert; Enduring all things, no matter how painful or difficult; Protection from danger and threats; Warmth and care, especially from a mother to a child; Chastity and abstinence from physical contact The stem is typically succulent, meaning it is adapted to store water. Cacti are often grown in greenhouses, particularly in regions unsuited to the cultivation of cacti outdoors, such the northern parts of Europe and North America. Illegal collecting of cacti from the wild continues to pose a threat. The ribbed or fluted stems of many cacti allow the stem to shrink during periods of drought and then swell as it fills with water during periods of availability. Cacti may also be described as shrubby, with several stems coming from the ground or from branches very low down, such as in Stenocereus thurberi. Their flowers may have superior ovaries (i.e., above the points of attachment of the sepals and petals), and areoles that produce further leaves. "[44], Bees are the most common pollinators of cacti; bee-pollination is considered to have been the first to evolve. If the base of your plant has become yellow or brown, then it could mean the cactus is already in a severe state. [59][60], The plant now known as Opuntia ficus-indica, or the Indian fig cactus, has long been an important source of food. Both contain mescaline. Nearly one in three cactus species at risk of extinction. It spread rapidly in the Mediterranean area, both naturally and by being introduced—so much so, early botanists assumed it was native to the area. A Cactus is just an office plant but deadlier. A cactus (plural cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. [36], Cacti inhabit diverse regions, from coastal plains to high mountain areas. Plants, flowers and other foliage symbolize emotions, ideas and actions. The meaning behind the coral is to let you know that now it is time for the pay off and play out of your phase. they are xerophytes), but the first ancestors of modern cacti were already adapted to periods of intermittent drought. When mature, the plant has … They can be tree-like (arborescent), meaning they typically have a single more-or-less woody trunk topped by several to many branches. [8] A few species differ significantly in appearance from most of the family. Spines, which are modified leaves, are present on even those cacti with true leaves, showing the evolution of spines preceded the loss of leaves. Like other types of succulents, cacti reduce this water loss by the way in which they carry out photosynthesis. [39], Rhipsalis baccifera is the exception; it is native to both the Americas and the Old World, where it is found in tropical Africa, Madagascar, and Sri Lanka. A mother’s love is strong and enduring just like a cactus! [10], Like their spines, cactus flowers are variable. Other succulent plants, such as the Aizoaceae in South Africa, the Didiereaceae in Madagascar and the genus Agave in the Americas, appear to have diversified at the same time, which coincided with a global expansion of arid environments. [86] The general recommendation of 25–75% organic-based material, the rest being inorganic such as pumice, perlite or grit, is supported by other sources. This is particularly true of tree-living cacti, such as Rhipsalis and Schlumbergera, but also of some ground-living cacti, such as Ariocarpus. [94], Although semi-desert cacti may be exposed to high light levels in the wild, they may still need some shading when subjected to the higher light levels and temperatures of a greenhouse in summer. Many live in extremely dry enviro… These vary from small "bumps" to prominent, nipple-like shapes in the genus Mammillaria and outgrowths almost like leaves in Ariocarpus species. Latin American examples include Parque Nacional del Pinacate, Sonora, Mexico and Pan de Azúcar National Park, Chile. Both the fruit and pads are eaten, the former often under the Spanish name tuna, the latter under the name nopal. [74] Cacti are one group of drought-resistant plants recommended for dry landscape gardening. Let's find out what they mean in your dreams: Symbolism: If your life has trapped you in situations that you feel are unavoidable, you may see a cactus in your dream. Stems have stomata and the formation of bark takes place later than in normal trees. Pereskia species have "normal" leaves, with a midrib and a flattened blade (lamina) on either side. that it should not be used as a genus name. Cactus is a Latin-inspired word from the ancient Greek life. [37] Precisely when after this split cacti evolved is less clear. That’s because bacterial necrosis strikes cacti only, and only certain species of cactus at that. For a mixed collection, a minimum temperature of between 5 °C (41 °F) and 10 °C (50 °F) is often suggested, except for cold-sensitive genera such as Melocactus and Discocactus. In a normal shoot, nodes bearing leaves or flowers would be separated by lengths of stem (internodes). In 1737, he placed the cacti he knew into two genera, Cactus and Pereskia. Almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. noun plural -tuses or -ti (-taɪ) any spiny succulent plant of the family Cactaceae of the arid regions of America. The genus Cereus was one of the first cactus genera to be described; the circumscription varies depending on the authority. Climbing cacti can be very large; a specimen of Hylocereus was reported as 100 meters (330 ft) long from root to the most distant stem. They also used to corral animals. [87] Roger Brown suggests a mixture of two parts commercial soilless growing medium, one part hydroponic clay and one part coarse pumice or perlite, with the addition of soil from earthworm castings. The prominence of these ribs depends on how much water the stem is storing: when full (up to 90% of the mass of a cactus may be water), the ribs may be almost invisible on the swollen stem, whereas when the cactus is short of water and the stems shrink, the ribs may be very visible. [86] In the case of cacti, there is general agreement that an open medium with a high air content is important. They make excellent hanging plants. Flowers are also produced from areoles. As of February 2012[update], it is not clear whether stem-based CAM evolved once only in the core cacti, or separately in the opuntias and cactoids;[9] CAM is known to have evolved convergently many times. Understanding evolution within the core cacti clade is difficult as of February 2012[update], since phylogenetic relationships are still uncertain and not well related to current classifications. A cactus has no limits in throwing the number of colleagues under the bus but generally singles out 1 certain colleague who is … [79], All cacti are included in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which "lists species that are not necessarily now threatened with extinction but that may become so unless trade is closely controlled." Stem shapes vary considerably among cacti. [11] In leafless cacti, areoles are often borne on raised areas on the stem where leaf bases would have been. [76] In addition to their use as psychoactive agents, some cacti are employed in herbal medicine. Mammillaria). The function of such leaves cannot be photosynthesis; a role in the production of plant hormones, such as auxin, and in defining axillary buds has been suggested. Tissue derived from the petals and sepals continues the pericarpel, forming a composite tube—the whole may be called a floral tube, although strictly speaking only the part furthest from the base is floral in origin. [61] The nopal industry in Mexico was said to be worth US$150 million in 2007. Various kinds of graft are used—flat grafts, where both scion and stock are of similar diameters, and cleft grafts, where a smaller scion is inserted into a cleft made in the stock. [75], Cacti have many other uses. Many cacti have roots that spread out widely, but only penetrate a short distance into the soil. Areoles are structures unique to cacti. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. [85] Another issue is the hardness of the water; where it is necessary to use hard water, regular re-potting is recommended to avoid the build up of salts. Attempts by the Roman Catholic church to suppress its use after the Spanish conquest were largely unsuccessful, and by the middle of the 20th century, peyote was more widely used than ever by indigenous peoples as far north as Canada. Some cacti produce "pads" or "joints" that can be detached or cleanly cut off. [68] Evidence indicates peyote was in use more than 5,500 years ago; dried peyote buttons presumed to be from a site on the Rio Grande, Texas, were radiocarbon dated to around 3780–3660 BC. [63], Almost any fleshy cactus fruit is edible. The delicate flowers usually bloom for a short period of time in the Spring. When sufficiently moist air is present, such as during fog or early morning mist, spines can condense moisture, which then drips onto the ground and is absorbed by the roots. Many cacti have short growing seasons and long dormancies, and are able to react quickly to any rainfall, helped by an extensive but relatively shallow root system that quickly absorbs any water reaching the ground surface. They lived in tropical areas that experienced periodic drought. The 1,500 to 1,800 species of cacti mostly fall into one of two groups of "core cacti": opuntias (subfamily Opuntioideae) and "cactoids" (subfamily Cactoideae). In plant or cactus Feng Shui, the yellowing of the plant represents the sign of death. Because cacti plants can survive in harsh conditions, they’ve become a symbol of unconditional, maternal love. Urban development and highways have destroyed cactus habitats in parts of Mexico, New Mexico and Arizona, including the Sonoran Desert. USDA Growing Zones: 9 to 11 The concentration of salts in the root cells of cacti is relatively high. The most famous among these is the Christmas cactus, which is native to Brazil. [45] As an example, Pachycereus schottii is pollinated by a particular species of moth, Upiga virescens, which also lays its eggs among the developing seeds its caterpillars later consume. However, cacti are very difficult to preserve in this way; they have evolved to resist drying and their bodies do not easily compress. Fusarium rot can gain entry through a wound and cause rotting accompanied by red-violet mold. All cacti have areoles—highly specialized short shoots with extremely short internodes that produce spines, normal shoots, and flowers. Opuntias (prickly pears) were used for a variety of purposes by the Aztecs, whose empire, lasting from the 14th to the 16th century, had a complex system of horticulture. A cactus actually symbolizes endurance as it is a plant that can really stand up to the test of time and the elements. [9], Pereskia clade B marks the beginnings of an evolutionary switch to using stems as photosynthetic organs. [45] The flowers of this cactus are funnel-shaped, white to deep pink, up to 4 cm (1.6 in) long, and open at night. The cactus as a gift represents some form of communication barrier that exists between two individuals. "Helminosporium rot" is caused by Bipolaris cactivora (syn. For example, of the 36 genera in the subfamily Cactoideae sampled in the research, 22 (61%) were found not monophyletic. The fruit of the saguaro (Carnegiea gigantea) has long been important to the indigenous peoples of northwestern Mexico and the southwestern United States, including the Sonoran Desert. Most cacti live in habitats subject to at least some drought. Cactus. The forest cacti grow in tropical and subtropical regions throughout the world. Cacti show many adaptations to conserve water. The 1905 Vienna botanical congress rejected the name Cactus and instead declared Mammillaria was the type genus of the family Cactaceae. [101] A very wet growing medium can cause both seeds and seedlings to rot. Cacti are also grown as houseplants, many being tolerant of the often dry atmosphere. [102] A temperature range of 18–30 °C (64–86 °F) is suggested for germination; soil temperatures of around 22 °C (72 °F) promote the best root growth. [55], Europeans first encountered cacti when they arrived in the New World late in the 15th century. Here, they may be kept in pots or grown in the ground. "[32], The two clades of Pereskia differ in their geographical distribution; with one exception, clade A is found around the Gulf of Mexico and the Caribbean Sea, whereas clade B occurs south of the Amazon Basin. These may only be moved between countries for scientific purposes, and only then when accompanied by both export and import permits. [10], Tall treelike habit (Pachycereus pringlei), Tall unbranched columnar habit (Cephalocereus), Shorter clustered columnar habit (Ferocactus pilosus), Solitary globular habit (Ferocactus echidne), Clustered globular habit (Rebutia species), The leafless, spiny stem is the characteristic feature of the majority of cacti (and all of those belonging to the largest subfamily, the Cactoideae). Cacti have a variety of uses: many species are used as ornamental plants, others are grown for fodder or forage, and others for food (particularly their fruit). One of these, his Cactus opuntia (now part of Opuntia ficus-indica), was described as "fructu majore ... nunc in Hispania et Lusitania" (with larger fruit ... now in Spain and Portugal), indicative of its early use in Europe. Areoles are an identifying feature of cacti. The stems of most cacti have adaptations to allow them to conduct photosynthesis in the absence of leaves. They are often climbing or epiphytic plants that cling to trees. The frames of wattle and daub houses built by the Seri people of Mexico may use parts of Carnegiea gigantea. [35], A more recent 2011 study using fewer genes but more species also found that Pereskia was divided into these two clades, but was unable to resolve the members of the "core cacti" clade. ‡Ôø‡Ã,˜‚±j,BÉ6pŽ)E!§BÆúVlÍÑ, ¤™ÝC $MfþÕÍá߆]B9Mx‡¨oiڑuB;²¨x †_è†_QU~F/`āôú"š×¥ŸôÙüPz³š¬k7Ér”€¯;d†……OÒ¦‹¬ê$JaSšêg–ó³‹ëUii9Ž(Yþ|÷-˜Í‰. Most spines are straight or at most slightly curved, and are described as hair-like, bristle-like, needle-like or awl-like, depending on their length and thickness. Many cactus species are pollinated by bats. [65], Fruit prepared from Stenocereus queretaroensis, Salad including sliced nopales (opuntia pads), A number of species of cacti have been shown to contain psychoactive agents, chemical compounds that can cause changes in mood, perception and cognition through their effects on the brain. It can be essential to know what type of message plants sent (so when someone gives you cactus for gift, you should know). With one exception, they are native to the Americas, where their range extends from Patagonia to British Columbia and Alberta in western Canada. Roots of cacti can be eaten by the larvae of sciarid flies and fungus gnats. [43] The need to attract pollinators has led to the evolution of pollination syndromes, which are defined as groups of "floral traits, including rewards, associated with the attraction and utilization of a specific group of animals as pollinators. [10], The spines of cacti are often useful in identification, since they vary greatly between species in number, color, size, shape and hardness, as well as in whether all the spines produced by an areole are similar or whether they are of distinct kinds. Thus, a 2011 study found "an extraordinarily high proportion of genera" were not monophyletic, so were not all descendants of a single common ancestor. Drier spiny fruits may cling to the fur of mammals or be moved around by the wind. The stamens usually arise from all over the inner surface of the upper part of the floral tube, although in some cacti, the stamens are produced in one or more distinct "series" in more specific areas of the inside of the floral tube. (you automatically placed yourself in the friend zone). Your cactus needs light to stay healthy and alive. Older sources suggest an early origin around 90 – 66 million years ago, during the Late Cretaceous. [10], Other cacti have a quite different appearance. ρός) and Latin words meaning "wax", "torch" or "candle". [50], As of March 2012[update], there is still controversy as to the precise dates when humans first entered those areas of the New World where cacti are commonly found, and hence when they might first have used them. In addition, sunlight will warm up the surface of the cactus to prevent moisture accumulation and the potential problems this can cause, such as mold or bacteria damaging the plant. Typically, the tube also has small scale-like bracts, which gradually change into sepal-like and then petal-like structures, so the sepals and petals cannot be clearly differentiated (and hence are often called "tepals"). [15] Cacti can also form new roots quickly when rain falls after a drought. [62] The Indian fig cactus was probably already present in the Caribbean when the Spanish arrived, and was soon after brought to Europe. [10], The stems of most cacti are some shade of green, often bluish or brownish green. [9], By studying the ratio of 14C to 13C incorporated into a plant—its isotopic signature—it is possible to deduce how much CO2 is taken up at night and how much in the daytime. [109] Several viruses have been found in cacti, including cactus virus X. Globular cacti may be solitary, such as Ferocactus latispinus, or their stems may form clusters that can create large mounds. Pereskia (which is close to the ancestral species from which all cacti evolved) does have long-lasting leaves, which are, however, thickened and succulent in many species. The practice of using various species of Opuntia in this way has spread from the Americas, where they naturally occur, to other regions where they grow, such as India. For the former genus, "Cacti" redirects here. The Bayesian consensus cladogram from this study is shown below. Cactus are surrounded and covered by thorns. [32] Nine tribes are recognized within Cactoideae in the International Cactaceae Systematics Group (ICSG) classification; one, Calymmantheae, comprises a single genus, Calymmanthium. For example, in 2002 in Korea alone, 49 million plants were propagated, with a value of almost US$9 million. Chlorophyll is present in leaves of most plants and helps in quick food production for plants. This term is usually applied to herbaceous non-woody plants plants or small shrubs rather than large shrubs or trees, but used strictly it also applies to the larger and longer-lived species. [97][85] Some cacti, particularly those from the high Andes, are fully frost-hardy when kept dry (e.g. [56] Thus, melocacti were possibly among the first cacti seen by Europeans. Recognized for its endurance and ability to thrive in trying environments, they are classified as stem succulents as they … [71] Several other species of Echinopsis, including E. peruviana, also contain mescaline. Torch Cactus: The torch cactus (cereus peruvianus) is a columnar cactus that can grow very large and is the stereotypical cactus for south-of-the-border cartoons. 5. The conversion of land to agriculture has affected populations of Ariocarpus kotschoubeyanus in Mexico, where dry plains were plowed for maize cultivation, and of Copiapoa and Eulychnia in Chile, where valley slopes were planted with vines. A number of centers of diversity exist. The word "cactus" is derived through Latin from the Ancient Greek κάκτος (kaktos), a name used by Theophrastus for a spiny plant,[25] which may have been the cardoon (Cynara cardunculus). All cacti have some adaptations to promote efficient water use. The construction of a dam near Zimapan, Mexico, caused the destruction of a large part of the natural habitat of Echinocactus grusonii. As you may be able to guess from the name, the Easter Cactus is a cousin to the Christmas Cactus. [9] A small number of cactus species in the tribes Hylocereeae and Rhipsalideae have become adapted to life as climbers or epiphytes, often in tropical forests, where water conservation is less important. [10], Cacti whose stems are even smaller may be described as globular (or globose). In Pereskia, a genus close to the ancestor of cacti, areoles remain active for much longer; this is also the case in Opuntia and Neoraimondia. For a more detailed discussion of the phylogeny of the cacti, see Classification of the Cactaceae. [10], Smaller cacti may be described as columnar. [92] Brown says that more cacti are lost through the "untimely application of water than for any other reason" and that even during the dormant winter season, cacti need some water. They are used for human food and as fodder for animals, usually after burning off their spines. [40] The alternative theory is the species initially crossed the Atlantic on European ships trading between South America and Africa, after which birds may have spread it more widely.[41]. However, when he published Species Plantarum in 1753—the starting point for modern botanical nomenclature—he relegated them all to one genus, Cactus. The syrup can also be fermented to produce an alcoholic drink. [20] A further problem is that as temperatures rise, the enzyme that captures CO2 starts to capture more and more oxygen instead, reducing the efficiency of photosynthesis by up to 25%. They consist of erect, cylinder-shaped stems, which may or may not branch, without a very clear division into trunk and branches. Reproduction: Cacti are flowering plants. The popularity of cacti means many books are devoted to their cultivation. The, The tallest living cactus is a specimen of, International Code of Nomenclature for algae, fungi, and plants, International Organization for Succulent Plant Study, Convention on International Trade in Endangered Species of Wild Fauna and Flora, "Windstorm Fells 78-Foot Cactus--Tallest in World", "The number of known plants species in the world and its annual increase", "Evolution of CAM and C4 Carbon‐Concentrating Mechanisms", "The Domestication of Artichoke and Cardoon: From Roman Times to the Genomic Age", "Seed morphology, polyploidy and the evolutionary history of the epiphytic cactus, "The Late Pleistocene dispersal of modern humans in the Americas", "Cactus-eating moth threatens favorite Mexican food", "Potexvirus diversity in Cactaceae from São Paulo State in Brazil", https://en.wikipedia.org/w/index.php?title=Cactus&oldid=990816511, Wikipedia indefinitely semi-protected pages, Articles containing Ancient Greek (to 1453)-language text, Pages using multiple image with auto scaled images, Articles containing potentially dated statements from February 2012, All articles containing potentially dated statements, Articles containing potentially dated statements from March 2012, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 November 2020, at 17:39. [54] The Aztecs symbolically linked the ripe red fruits of an opuntia to human hearts; just as the fruit quenches thirst, so offering human hearts to the sun god ensured the sun would keep moving. Even those who want the meaning itself to be mysterious will usually do something extra to the design to make it stick out more than a basic cactus would. The plant stores the carbon dioxide it takes in as malic acid, retaining it until daylight returns, and only then using it in photosynthesis. It is now used formally by the Native American Church. They can provide some shade, which lowers the temperature of the surface of the cactus, also reducing water loss. Cactus plants … Cacti occur in a wide range of shapes and sizes. In the genus Pereskia, the branches are covered with leaves, so the species of this genus may not be recognized as cacti. [12] The structure of the leaves varies somewhat between these groups. These strategies included being able to respond rapidly to periods of rain, and keeping transpiration low by using water very efficiently during photosynthesis.
