Prickly Pears In Australia
Prickly pears (genus '' Opuntia'') include a number of plant species that were introduced and have become invasive in Australia. Prickly pears (mostly ''Opuntia stricta'') were imported into Australia in the First Fleet as hosts of cochineal insects, used in the dye industry. Many of these, especially the tiger pear, quickly became widespread invasive species, rendering of farming land unproductive. The moth '' Cactoblastis cactorum'' from Argentina, whose larvae eat prickly pear, was introduced in 1925 and almost wiped out the prickly pear. This case is often cited as an example of successful biological pest control. A monument to ''Cactoblastis cactorum'' was erected in Dalby, Queensland, commemorating the eradication of the prickly pear in the region. The Cactoblastis Memorial Hall in Boonarga, Queensland, also commemorates the eradication. Species These ''Opuntia'' species are recorded as naturalised in Australia: *''Opuntia aurantiaca'' *'' Opuntia dejecta'' *'' O ...

Cactoblastis Memorial Hall
Cactoblastis Memorial Hall is a heritage-listed memorial at Warrego Highway, Boonarga, Western Downs Region, Queensland, Australia. It was built in 1936 by Jack Schloss. It was added to the Queensland Heritage Register on 21 September 1993. History This timber hall was completed in 1936 at Boonarga, a small settlement approximately southeast of Chinchilla. The hall was erected as a monument to the cactoblastis moth which overcame prickly pear in Queensland and New South Wales during the late 1920s and early 1930s. The appearance of prickly pear in Queensland has been attributed to a small number of prickly pear plants brought to Queensland as garden plants. By 1862 prickly pear was growing in the Chinchilla district and spread rapidly in areas where land holdings were extensive and population relatively low. Prickly pear was declared a noxious weed in Queensland in 1893. By 1900 approximately were affected by prickly pear; an area which had extended to an estimate ...

Opuntia Monacantha
''Opuntia monacantha'', commonly known as drooping prickly pear, cochineal prickly pear, or Barbary fig, is a species of plant in the family Cactaceae native to South America. Taxonomy The species was first formally described in 1812 by botanist Adrian Haworth in ''Synopsis Plantarum Succulentarum''. The name ''Opuntia vulgaris'', which is a synonym of ''Opuntia ficus-indica'', has been misapplied to this species in Australia. From Adrian Hardy Haworth, the species was in the genus 1819 Opuntia. Many authors, including Nathaniel Lord Britton, Joseph Nelson Rose and Curt Backeberg stated that Opuntia monacantha was just another name for Opuntia vulgaris. Description Opuntia monacantha is a succulent, thorny shrub that grows almost tree-like with several branches and profusely expanded crown in branches that reaches a height of up to 5 meters. The oval to elongated shoots narrowed at the base are shiny green. They are quite thin and four to ten inches long. The widely spaced ...

Opuntia Microdasys
''Opuntia microdasys'' (angel's-wings, bunny ears cactus, bunny cactus or polka-dot cactus) is a species of flowering plant in the cactus family Cactaceae, native and endemic to central and northern Mexico. Description ''Opuntia microdasys'' forms a dense shrub 40–60 cm tall, occasionally more, composed of pad-like stems 6–15 cm long and 4–12 cm broad. Instead of spines it has numerous white or yellow glochids 2–3 mm long in dense clusters. They are barbed and thinner than the finest human hairs, detaching in large numbers upon the slightest touch. If not removed they will cause considerable skin irritation so the plants must be treated with caution. The Latin specific epithet ''microdasys'' means “small and hairy”. The yellow flowers appear only rarely. Despite this, it is a very popular cactus in cultivation, partly because of the young plant’s comical resemblance to a rabbit’s head. It has gained the Royal Horticultural Society’s Aw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opuntia Leucotricha
''Opuntia leucotricha'' is a species of cactus with the common names: arborescent pricklypear, Aaron's beard cactus, and semaphore cactus; and (in Spanish) ''duraznillo blanco'' and ''nopal blanco''. Distribution It is a species of '' Opuntia'' (prickly pear) that is endemic to Mexico. The cactus occurs in mountain habitats, in the states of: San Luis Potosí, Tamaulipas, Zacatecas, Guanajuato, and Querétaro. Description ''Opuntia leucotricha'' is a tree-like cactus, growing up to tall. The platyclades have a thin fuzz of white hairs on their joints.

Opuntia Humifusa
''Opuntia humifusa'', commonly known as the devil's-tongue, Eastern prickly pear or Indian fig, is a cactus of the genus ''Opuntia'' present in parts of the eastern United States. Description As is the case in other ''Opuntia'' species, the green stems of this low-growing perennial cactus are flattened, and are formed of segments. Barbed bristles are found around the surfaces of the segments, and longer spines are sometimes present. The flowers are yellow to gold in color, and are found along the margins of mature segments. The flowers are waxy and sometimes have red centers. They measure across. This cactus blooms in the late spring. The juicy red or purple fruits measure from . As the fruit matures, it changes color from green to red, and often remains on the cactus until the following spring. There are 6 to 33 small, flat, light-colored seeds in each fruit. Taxonomy Some botanists treat this cactus as a variety of '' O. compressa'': hence ''O. c.'' var. ''humifusa'', or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opuntia Ficus-indica
''Opuntia ficus-indica'', the Indian fig opuntia, fig opuntia, or prickly pear, is a species of cactus that has long been a domesticated crop plant grown in agricultural economies throughout arid and semiarid parts of the world. ''O. ficus-indica'' is the most widespread and most commercially important cactus. It is grown primarily as a fruit crop, and also for the vegetable nopales and other uses. Cacti are good crops for dry areas because they efficiently convert water into biomass. ''O. ficus-indica'', as the most widespread of the long-domesticated cactuses, is as economically important as maize and blue agave in Mexico. ''Opuntia'' species hybridize easily, but the wild origin of ''O. ficus-indica'' is likely to have been in central Mexico, where its closest genetic relatives are found. Names Most culinary references to the "prickly pear" refer to this species. The Spanish name ''tuna'' is also used for the fruit of this cactus and for ''Opuntia'' in general; according to ...

Opuntia Engelmannii
''Opuntia engelmannii'' is a prickly pear common across the south-central and Southwestern United States and northern Mexico. It goes by a variety of common names, including desert prickly pear, discus prickly pear, Engelmann's prickly pear in the US, and nopal, abrojo, joconostle, and vela de coyote in Mexico. The nomenclatural history of this species is somewhat complicated due to the varieties, as well as its habit of hybridizing with ''Opuntia phaeacantha''. It differs from ''Opuntia phaeacantha'' by being green year round instead of turning reddish purple during winter or dry seasons, as well as having yellow flowers with red centers. Varieties *''Opuntia engelmannii'' var. ''cuija'' — nopal cuijo; endemic to Mexico, in Guanajuato, Hidalgo, San Luis Potosí. *''Opuntia engelmannii'' var. ''engelmannii'' — Engelmann's prickly pear; Mexico, southwestern U.S., California *''Opuntia engelmannii'' var. ''flavispina'' — yellow-spined prickly pear; Arizona, Mexico *''Op ...
