== Etymology ==
The name is derived from the Greek ''dis'' (twice) and refers to the equal length of the inner and outer flower segments, a distinguishing feature of the genus as originally described.

== Description ==
'''Disocactus''' is a genus of epiphytic or lithophytic cacti (growing on trees or rocks). They possess either ribbed or flattened stems known as **phylloclades**. Spines are usually minimal, setose (bristle-like), or entirely absent, while areoles are often numerous along the stem margins.

* '''Flowers:''' Typically diurnal (day-blooming) and self-sterile. Most species are pollinated by hummingbirds. The flowers are large and come in various shapes (funnel-shaped, tubular, or rarely rotate), with colors ranging from white and pink to deep red or purple. A key feature is that the stamens are arranged in two distinct series.
* '''Fruits:''' Small, berry-like fruits that are mostly naked or have very few scales.
* '''Seeds:''' Ovate, black or brown, and covered in a mucilaginous envelope which aids in dispersal in tropical environments.

== Habitat ==
These cacti are found in the tropical cloud forests of Southern Mexico and Central America. They grow as epiphytes in high-humidity environments at altitudes ranging from 700 m to 2100 m.

== Distribution ==
* '''Mexico:''' Chiapas, Colima, Durango, Guerrero, Jalisco, Mexico D.F., Michoacán, Morelos, Nayarit, Oaxaca, Sinaloa, Veracruz.
* '''Central America:''' El Salvador, Guatemala, Honduras, Nicaragua.

== Species ==
Following the strict circumscription of Joël Lodé (excluding ''Aporocactus'' and ''Heliocereus''), the genus contains 8 recognized species:

* [[Disocactus ackermannii]]
* [[Disocactus biformis]]
* [[Disocactus eichlamii]]
* [[Disocactus macdougallii]]
* [[Disocactus macranthus]]
* [[Disocactus nelsonii]]
* [[Disocactus phyllanthoides]]
* [[Disocactus quetzaltecus]]

== Taxonomy and Comments ==
The classification of ''Disocactus'' has been a subject of intense debate among botanists like Kimnach, Barthlott, and Hunt.
* '''Current Status:''' Joël Lodé follows the molecular evidence suggesting that ''Disocactus'' s.l. is polyphyletic. Consequently, he maintains '''Aporocactus''' and '''Heliocereus''' as separate genera based on the characteristics of their floral receptacles.
* '''Reassignments:'''
** ''D. flagelliformis'' and ''D. martianus'' are moved to '''Aporocactus'''.
** ''D. speciosus'' and the recently described ''D. lodei'' are moved to '''Heliocereus'''.
** ''D. amazonicus'' is reassigned to '''Pseudorhipsalis'''.
** ''D. testudo'' and ''D. wittii'' are moved back to '''Strophocactus'''.
