M&J Cactus Wiki International Encyclopedia of Cactaceae This classification follows the Joël Lodé system (v1.19), complemented with modern phylogenetic insights. Some genera reflect collector usage and may differ from current molecular-based taxonomy.

Classification of the Family Cactaceae

Tribe Austrocylindropuntieae

• Austrocylindropuntia, Cumulopuntia, Punotia

Tribe Cylindropuntieae

• Cylindropuntia, Grusonia, Pereskiopsis, Quiabentia

Tribe Opuntieae

• Airampoa (often treated as Tunilla), Brasiliopuntia, Consolea, Miqueliopuntia, Opuntia, Salmonopuntia (disputed), Tacinga

Tribe Pterocacteae

• Pterocactus

Tribe Tephrocacteae
