The 1905 Vienna botanical congress rejected the name Cactus and instead declared Mammillaria was the type genus of the family Cactaceae. It did, however, conserve the name Cactaceae, leading to the unusual situation in which the family Cactaceae no longer contains the genus after which it was named. [33] cactus, (family Cactaceae), flowering plant family (order Caryophyllales) with nearly 2,000 species and 139 genera.
Cacti are native through most of the length of North and South America, from British Columbia and Alberta southward; the southernmost limit of their range extends far into Chile and Argentina. Cactaceae is defined as a family of plants that includes from 50 to 150 genera and about 2000 species, primarily xerophytes native to the Americas, characterized by succulent stems that store water and often bear spines and flowers.

cactaceae care, Contributed by Aidan Campos & Alan Weakley. Key to Cactaceae. Identify plants and flowers of the Cactus family (Cactaceae) with these wildflower identification tools and a photo gallery with plants grouped according to families. The Cactaceae maintain an unusually complete representation of their phylogenetic history. Subfamily Pereskioideae, with the least-derived traits, consists of trees, shrubs, or scrambling "vines" with broad, seasonally deciduous leaves and terete stems that are only weakly succulent. A cactus is a member of the plant family Cactaceae.
The word "cactus" derives, through Latin, from the Ancient Greek "kaktos," a name originally used by Theophrastus for a spiny plant whose identity is not certain.
