Zygomorphic flower, probably of a cultivar in the S. Truncata Group, cut in half to show its internal structure. In the wild, the species of Schlumbergera grow either on trees or on rocks and can form sizeable shrubs with woody bases; a height of up to 1.2 m (4 ft) has been reported for one species (S. opuntioides).

The saguaro is a columnar cactus that grows notable branches, usually referred to as arms.Over 50 arms may grow on one plant, with one specimen having 78 arms. [6] Saguaros grow from 3–16 m (10–52 ft) tall, and up to 75 cm (30 in) in diameter.
Wild populations of K. grusonii were adversely affected in the 1990s as a result of wild specimens being poached as well as the creation of the Zimapán Dam and reservoir (in Hidalgo). [1] The golden barrel cactus is a fairly adaptable species, but naturally prefers growing in rich, volcanic (but well-aerated) soil on sunny slopes, where water ...
Schlumbergera truncata, the false Christmas cactus, [1] is a species of plant in the family Cactaceae. Because it produces a flower, it also belongs to the taxonomic group Magnoliophyta and is thus considered an angiosperm. [ 2 ]

[18] O. ficus-indica grows in many frost-free areas of the world, including the Southern United States. [19] It is naturalized with widespread distribution in Greece. [20]
Several taxa are threatened with extinction at least in the wild, due to habitat destruction and especially overcollecting for the pot plant trade. Cactus fanciers can assist conservation of these rare plants by choosing nursery-bred specimens (wild-collected ones are illegal to possess for the rarest species). Several mammillarias are ...
