Opuntioideae

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.

Opuntioideae is a subfamily of the cactus family, Cactaceae. It contains 15 genera divided into five tribes. The subfamily encompasses roughly 220–250 species, and is geographically distributed throughout the New World from Canada, to Argentina. Members of this subfamily have diverse habits, including small geophytes, hemispherical cushions, shrubs, trees, and columnar cacti consisting of indeterminate branches or determinate terete or spherical segments.

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.

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