Disocactus is a genus of epiphytic cacti in the tribe Hylocereeae found in Central America, the Caribbean and northern South America.[1] It should not be confused with Discocactus, which is a different genus.

Species of Disocactus grow in tropical regions either on trees as epiphytes or on rocks as lithophytes. They have two distinct growth habits. Species such as D. phyllanthoides have stems which are round at the base but then become flattened and leaflike.[1]

Many of the cultivated plants known as epiphyllum hybrids or just epiphyllums are derived from crosses between species of Disocactus (rather than Epiphyllum) and other genera in the Hylocereeae.[2]


The boundaries of the genera in the tribe Hylocereeae have been subject to considerable change and uncertainty, which is reflected in the number of names which have been used for Disocactus:[1]

Bonifazia Standl. & Steyerm.
Chiapasia Britton & Rose
Heliocereus (A.Berger) Britton & Rose
Lobeira Alexander
Nopalxochia Britton & Rose
Pseudonopalxochia Backeb.
Wittia K.Schum.
Wittiocactus Rauschert

Pseudorhipsalis is sometimes included in Disocactus, but it is kept separate by the International Cactaceae Systematics Group.[1] Aporocactus is formerly included in Disocactus, but it should be a genus on its own according to molecular evidence.[3][4]

As of March 2021, Plants of the World Online accepted the following species:[5]
