Disocactus is a genus of epiphytic cacti in the tribe Hylocereeae found in Central America, the Caribbean and northern South America. 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. 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.
The one illustrated here is blooming in our garden at the moment and is probably a Disocactus × jenkinsonii is a hybrid between Disocactus phyllanthoides and Disocactus speciosus. It is perhaps the most commonly grown orchid cactus and seems to survive and flower under most conditions. It has a very complex taxonomic history and has been mistaken for Disocactus ackermannii for a long time.
