Opuntioideae genera

Opuntia, commonly called the prickly pear cactus, is a genus of flowering plants in the cactus family Cactaceae, many known for their flavorful fruit and showy flowers. Cacti are native to the Americas, and are well adapted to arid climates; however, they are still vulnerable to alterations in precipitation and temperature driven by climate change. The plant has been introduced to Australia, southern Europe, the Middle East, and parts of Africa.

Cylindropuntia is a genus of cacti (family Cactaceae), containing species commonly known as chollas ( ), native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant.

Austrocylindropuntia is a genus of cacti (family Cactaceae) with eight recognized species , which were once included in the genus Opuntia. All are native to South America, although some have been introduced elsewhere.

Pterocactus (from Greek pteron, "wing", referring to the saucer-shaped seed of these plants) is a genus of the cactus family (Cactaceae), comprising 9 species. All Pterocactus have tuberous roots and are endemic to South and Western Argentina. The genus has been given its own tribe, the Pterocacteae. A molecular phylogenetic analysis placed the genus in the tribe Tephrocacteae.

Pereskiopsis is a genus of cactus (family Cactaceae) in the subfamily Opuntioideae. Unlike typical cacti, it has persistent fleshy leaves. The genus name refers to its resemblance to the genus Pereskia. Most species are found in Mexico south through Guatemala to Honduras, with one species in Bolivia. The incorrect spelling Peireskiopsis has also been used.

Tephrocactus (from Greek tephra, "ash", referring to the color of these plants' epidermis) is a genus of the cactus family (Cactaceae). ==Species== Species of the genus Tephrocactus according to Plants of the World Online as of October 2025:

Maihueniopsis (from Greek opsis, "view", referring to its resemblance to the unrelated Maihuenia) is a genus of the cactus family (Cactaceae), containing 18 species.

thumb|right|Grusonia parishiorum Grusonia is a genus of opuntioid cacti (family Cactaceae), originating from the North American Deserts in Southwest United States and northern Mexico, including Baja California. Authors differ on precise boundaries of the genus, which has been included in Cylindropuntia. Corynopuntia, also known as club chollas (or "perritos" in Mexico), is now a synonym, with the genus originally being described by Knuth in 1935. Molecular phylogenetic studies suggest that it should be included in Grusonia, a view accepted by Plants of the World Online .

Cumulopuntia is a genus of cactus (family Cactaceae). This is a poorly defined genus, with constant change to what species fall under it and whether it should even be a separate genus from Opuntia, which it is often interchanged with. It was defined by Friedrich Ritter in 1980 by redefining multiple species in Tephrocactus and Opuntia. Still more work needs to be done to circumscribe Cumulopuntia as it stands.

Tacinga is a genus in the cactus family Cactaceae, native to northeast Brazil (from northeast Minas Gerais to southern Rio Grande do Norte, including Bahia, Sergipe, Alagoas, Pernambuco and Paraíba). Once thought to be monotypic, the genus now comprises 10 species and 3 hybrids. ==Species== As of 2025, Plants of the World Online accept these species: {| class="wikitable" |- ! Image !!

Consolea is a genus of cactus, named after Italian botanist Michelangelo Console. Members of the genus are native to the West Indies and Florida in the United States. Members of this genus consist of trees up to 10 m in height; they are dioecious or subdioecious.

Quiabentia is a genus of cacti, closely related to Pereskiopsis. ==Description== The tree-like or bushy xerophytic species of the genus Quiabentia have whorled, fleshy, round branches that produce flat, fleshy leaves. The leaves are broadly ovate to spatulate and up to 7 centimeters long. Their areoles are covered with glochids and numerous spines.
