407.0000 Family Cactaceae Juss.; Gen. Pl. [Jussieu] 310 (1789), nom. cons.
ca. 140-170 genera (circumscription still very much in flux), ca. 1700-1800 spp. Latest phylogeny: de Vos et al. (2025). There has been excessive splitting, leading to over 3000 species in some collectors view. It should be good practice in the future that each ´new species´ description is confirmed by molecular genetics, not only by morphology.
