Hylocereus is a genus of cacti, often referred to as night-blooming cactus (though the term is also used for many other cacti). Several species have large edible fruits, which are known as pitahayas or dragonfruits. Whether Hylocereus is a distinct genus is uncertain as of July 2013.

Taxonomy

In the classification of the International Cactaceae Systematics Group of the International Organization for Succulent Plant Study, the genus Hylocereus is one of the six genera of the tribe Hylocereeae. In this classification, the genus Wilmattea Britton & Rose is included in Hylocereus.[1] A 2011 study of the molecular phylogeny of the Cactaceae concluded that neither the tribe nor the genus was monophyletic (i.e. neither comprised all the descendants of a common ancestor). Two species of Hylocereus formed a clade with two species of Selenicereus, suggesting that the genera were not distinct.[2]
