Cylindropuntia

Cylindropuntia is a genus of cacti (family Cactaceae), containing species commonly known as chollas, native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant.

Taxonomy

Cylindropuntia was formerly treated as a subgenus of Opuntia, but have now been separated based on their cylindrical stems (Opuntia species have flattened stems) and the presence of papery epidermal sheaths on the spines (Opuntia has no sheaths).[1] A few species of mat- or clump-forming opuntioid cacti are currently placed in the genus Grusonia. Collectively, opuntias, chollas, and related plants are sometimes called opuntiads.[2]

The roughly 35 species of Cylindropuntia are native to the southwestern and south-central United States, Mexico, and the West Indies. The Flora of North America recognizes 22 species.[3] Some species have been introduced to South America (Chile, Ecuador, Peru) and South Africa.[3]

Notes
  1. A binomial authority in parentheses indicates that the species was originally described in a genus other than Cylindropuntia.
gollark: The best way to do proofs is to test it in one case, and assume it's right the rest of the time.
gollark: The solution was obviously just to use columns.
gollark: They had some issues when they realized that Excel only supported 65536 rows.
gollark: I just write code and test it on on OS on one CPU architecture in very specific conditions, but I do it without loss of generality.
gollark: He was clearly eaten by bees.
