Cylindropuntieae
In 1984, the International Organization for Succulent Plant Study set up a working party, now called the International Cactaceae Systematics Group, to produce a consensus classification of the cactus family, down to the level of genus. Their classification has been used as the basis for systems published since the mid-1990s. Treatments in the 21st century have generally divided the family into around 125–130 genera and 1,400–1,500 species, which are then arranged in a number of tribes and subfamilies. However, subsequent molecular phylogenetic studies have shown that a very high proportion of the higher taxa (genera, tribes and subfamilies) are not monophyletic, i.e. they do not contain all of the descendants of a common ancestor. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Overview The classification ...

Opuntieae
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. Description Synapomorphies of Opuntioideae include small deciduous, barbed spines called glochids born on areoles and a bony aril surrounding a campylotropous ovule (inverted and curved, such that the micropyle almost meets the funiculus). Other prominent morphological characters for this subfamily are presence of cylindrical, caducous leaves that tend to be shed by maturity and the sectioning of the stem into joints or pads known as cladodes. Opuntioideae are unique among cacti for lacking in the stem a thick cortex, an exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pereskiopsis
''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. Description Species of ''Pereskiopsis'' do not have the typical appearance of most cacti, including those in the subfamily Opuntioideae to which it belongs, since they have persistent fleshy leaves. They mostly have a shrubby or treelike growth habit, although some scramble or climb. Their stems have a round cross section and are not divided into segments. Their leaves are flat, succulent and generally long-lasting, and of various shapes, including elliptical and almost round. The characteristic areoles of cacti are present, and usually have glochids marking them as members of the Opuntioideae as well as needle-l ...

Cumulopuntia
''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. Species list Accepted species: * '' Cumulopuntia boliviana'' (Salm-Dyck) F.Ritter * '' Cumulopuntia boliviana WG086'' (Salm-Dyck) F.Ritter * '' Cumulopuntia rossiana'' (Heinrich & Backeb.)
