The term "genus cereus" refers to a taxonomic classification in the field of biology, specifically in the realm of botany. It is a genus name that is part of the larger family Cactaceae, which encompasses various species of cacti.
The genus cereus primarily includes a group of columnar or tree-like cacti that are native to regions of Central and South America, as well as the Caribbean islands. These cacti are characterized by their tall, cylindrical stems that typically grow upright and have a ribbed or segmented appearance. The stems are often covered in sharp spines for protection against herbivores and other threats in their natural habitat.
