[8] The ICSG classification divides the subfamily Cactoideae into nine tribes. However, phylogenetic research has ...

Six subtribes were proposed in a 2023 study. The table below compares the 2023 classification with a widely used 2010 classification. [2] [4] As of December 2024, Plants of the World Online accepted some genera that were treated as synonyms in the 2010 and 2023 studies. These genera are included in the table together with a note of the name ...
The tribe includes large treelike species, as well as shorter shrubby species. [1] Some species can grow to be over 15 m (50 ft) tall, like the saguaro (Carnegiea gigantea) [2] and Cephalocereus macrocephalus (syn. Neobuxbaumia macrocephala). [3] Their stems are ribbed and columnar, not divided into segments. Most have flowers that open at ...
