| Opuntia arenaria Engelmann | |
Opuntia arenaria was considered a variety of O. polyacantha by many botanists, and is still treated that way in the Flora of North America. [1] However, O. arenaria is diploid and O. polyacantha is tetraploid. It was described by Engelmann in 1856. [2]
Opuntia arenaria can grow in soil that is essentially pure sand. It has rhizomes up to 1.5 m long that give rise to above ground shoots with small cladodes that are 4-7 x 2–3 cm in size. Major spines are found in the distal areoles and are often reflexed, up to 30 mm long. Minor spines are strongly deflexed and much shorter. Overall, plants (clumps) of cladodes may be 20–30 cm across and about 4–8 cm tall. Fruits are small, about 2.5 cm.
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 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.
Opuntia ficus-indica, the 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. Likely having originated in Mexico, O. ficus-indica is the most widespread and most commercially important cactus.
The strawberry hedgehog cactus or Engelmann's hedgehog cactus is commonly found in desert areas of the southwestern United States and the adjacent areas of Mexico, including the states of California, Nevada, Utah, Arizona, Baja California and Sonora.
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 cow's tongue cactus, cow tongue prickly pear, desert prickly pear, discus prickly pear, Engelmann's prickly pear, and Texas prickly pear in the US, and nopal, abrojo, joconostle, and vela de coyote in Mexico.
Yucca gloriosa is a species of flowering plant in the family Asparagaceae, native to the southeastern United States. Growing to 2.5 m (8 ft), it is an evergreen shrub. It is widely cultivated as an ornamental for its architectural qualities, and has reportedly become established in warmer climates in the wild in various parts of the world.
Opuntia basilaris, the beavertail cactus or beavertail pricklypear, is a cactus species found in the southwest United States. It occurs mostly in the Mojave, Anza-Borrego, and Colorado Deserts, as well as in the Colorado Plateau and northwest Mexico. It is also found throughout the Grand Canyon and Colorado River region as well as into southern Utah and Nevada, and in the western Arizona regions along the Lower Colorado River Valley.
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 eastern North America.
Opuntia fragilis, known by the common names brittle pricklypear and little prickly pear, is a prickly pear cactus native to much of western North America as well as some midwestern states such as Illinois, Iowa, Wisconsin and Michigan. It also occurs in several Canadian provinces. It is known from farther north than any other cactus, occurring at as far as 56°N latitude in British Columbia. There is an isolated and possibly genetically unique population in Eastern Ontario known as the "Kaladar population".
Opuntia, commonly called prickly pear, is a genus of flowering plants in the cactus family Cactaceae. Prickly pears are also known as tuna (fruit), sabra, nopal from the Nahuatl word nōpalli for the pads, or nostle, from the Nahuatl word nōchtli for the fruit; or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary species is the Indian fig opuntia.
Cylindropuntia echinocarpa is a species of cactus known by the common names silver cholla, golden cholla, and Wiggins' cholla. It was formerly named Opuntia echinocarpa.
Grusonia parishii is a species of cactus known by the common names matted cholla and Parish club cholla. It is native to the Mojave and Sonoran Deserts of California and Arizona.
Opuntia aciculata, also called Chenille pricklypear, old man's whiskers, and cowboy's red whiskers, is a perennial dicot and an attractive ornamental cactus native to Texas. It belongs to the genus Opuntia prickly pear cacti. It is also widespread in Nuevo Leon, Tamaulipas.
Opuntia polyacantha is a common species of cactus known by the common names plains pricklypear, hairspine cactus, panhandle pricklypear, and starvation pricklypear. It is native to North America, where it is widespread in Western Canada, the Great Plains, the central and Western United States, and Chihuahua in northern Mexico.
Sclerocactus sileri, the Siler fishhook cactus, is a rare and very small cactus found mostly in mineral-rich desert areas of intermediate elevations, notably in the American states of Utah, Nevada, and northern Arizona.
Opuntia pinkavae, common names Bulrush Canyon prickly-pear or Pinkava's pricklypear, is a species of cactus known only from northern Arizona and southern Utah. It grows in sunny locations in grasslands, on the edges of pinyon-juniper woodlands, on sandy or limestone soils.
Opuntia rufida is a species of prickly pear cactus native to southwestern Texas and northern Mexico, where it grows on rocky slopes. The species makes up for its total lack of spines with a profusion of red-brown glochids. The common name blind prickly pear or cow blinder comes from the fact that the glochids may be carried away by the wind and blind animals.
Opuntia lindheimeri is a species of cactus native to North America. It is native to Mexico and the United States, where its populations are primarily in Texas.
Opuntia abjecta is a short cactus, perhaps to 15(25) cm tall. It occurs in the Florida Keys and has been conflated with O. triacantha. Recent work shows that the two taxa are distinct. In addition to morphological and phylogenetic (DNA) differences, O. triacantha occurs in Cuba, whereas O. abjecta occurs in Florida. Currently It is Listed as critically by the IUCN Red List.
Opuntia cacanapa is a cactus in the genus Opuntia. In the United States it is found primarily in the southern Trans-Pecos and the South Texas Plains from Brewster, Pecos and Uvalde Counties south to Cameron County. It also occurs in nearby Mexico from the Rio Grande to as far south as Guanajuato and northern Hidalgo.
Opuntia sulpurea falls under the Opuntia, or prickly pear, genus within the family Cacataceae named such because of their round shape, green color, and long thick spines. Opuntia sulphurea is the widest spread of the Opuntia that can be found in and around Argentina, occupying mostly arid areas of the region from the plains in the Western portion of Argentina up to much higher altitudes on the Eastern side of the Andes mountain range. As a result of its ability to survive in such a diverse array of environments there are several subspecies of O. sulphurea that are identifiable based on the number of spine per areole, for example. A commonality across the three is a bright yellow flower, often considered to be the color of sulfur, from which the species name is derived. As with several other species of Opuntia, these prickly pears tend to grow in groups, forming clumps that can reach one to two meters in diameter, but while other species within the genus grow upwards as well O. sulphurea tend to stay low to the ground. As a result of its tendency to grow in dry, arid, and rocky areas this cactus has evolved to be very resilient, not even suffering from the effects of agriculture, i.e. cattle grazing, on lower altitude subpopulations.
