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. [2] Currently It is Listed as critically by the IUCN Red List.

Details

O. abjecta grows on humus over limestone or even on bare limestone. Cladodes are typically 2.5 cm long by 4–5 cm long. The cladodes do not shatter, but do deattach from each other with some ease. O. abjecta is a small plant with radiating branches, a subshrub. Retrorsely barbed spines are reddish-brown as they develop; they mature to pale white (not bright white). Zero to three spines are produced by terminal cladodes. Generally, the spines of O. abjecta are shorter than 4 cm. The flower bud of O. ajbjecta is rounded (not acute). O. abjecta has teardrop-shaped leaves. The seeds are about 4 mm in diameter.

<i>Opuntia ficus-indica</i> Species of cactus

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 convert water into biomass efficiently. O. ficus-indica, as the most widespread of the long-domesticated cactuses, is as economically important as maize and blue agave in Mexico. Because Opuntia species hybridize easily, the wild origin of O. ficus-indica is likely to have been in Mexico due to the fact that its close genetic relatives are found in central Mexico.

Opuntia phaeacantha is a species of prickly pear cactus known by the common names tulip prickly pear and desert prickly pear found across the southwestern United States, lower Great Plains, and northern Mexico. The plant forms dense but localized thickets. Several varieties of this particular species occur, and it also hybridizes easily with other prickly pears, making identification sometimes tricky.

<i>Opuntia basilaris</i> Species of cactus

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.

<i>Opuntia humifusa</i> Species of cactus

<i>Opuntia repens</i> Species of cactus

Opuntia repens, the roving pricklypear, is a species of cactus that is native to dry forests Puerto Rico and the Virgin Islands. It is a small shrub, growing up to 50 cm (20 in) tall, with yellow flowers and red fruit. Like its cousins, "jumping cholla" Opuntias of the Mojave, Sonoran, and Colorado deserts, it propagates by a segment dislodging after spines are caught in a large mammal's fur, whereby the segment is transported to another location. This is in addition to propagation by seed.

<i>Opuntia fragilis</i> Species of cactus

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".

<i>Opuntia</i> Genus of cactus

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.

<i>Opuntia littoralis</i> Species of cactus

Opuntia littoralis is a species of prickly pear cactus known by the common name coastal pricklypear. It is sometimes called the sprawling prickly pear due to its short stems and habit of growing close to the ground. "Littoral" means "pertaining to the seashore".

<i>Opuntia polyacantha</i> Species of cactus

Opuntia polyacantha is a common species of cactus known by the common names plains pricklypear, hairspine cactus, panhandle pricklypear, and starvation pricklypear.

<i>Opuntia rufida</i> Species of cactus

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 ammophila, the devil's-tongue, is a species of prickly pear cactus in Florida. Individuals typically occur singly and do not generally form dense thickets. O. ammophila was once considered a variety of O. humifusa; however, it is a distinct species. Among their many differences, O. ammophila has gray-green cladodes rather than green or grass-green.

<i>Opuntia arenaria</i> Species of cactus

Opuntia arenaria was considered a variety of O. polyacantha by many botanists, and is still treated that way in the Flora of North America. However, O. arenaria is diploid and O. polyacantha is tetraploid. It was described by Engelmann in 1856.

<i>Opuntia cacanapa</i> Species of cactus

<i>Opuntia hyptiacantha</i> Species of cactus

<i>Opuntia sulphurea</i> Species of cactus

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.
