The Hylocereeae are a tribe of cacti. Most are found in the tropical forests of Central and northern South America, and are climbers or epiphytes, unlike most cacti. The tribe includes between six and eight genera in different circumscriptions. The plants known as "epiphyllum hybrids" or "epiphyllums", widely grown for their flowers, are hybrids of species within this tribe, particularly Disocactus, Pseudorhipsalis and Selenicereus, less often Epiphyllum, in spite of the common name.

==Description== The members of the tribe are very variable in their morphology, especially when the terrestrial Acanthocereus is included. Many species form aerial roots. The hylocereoid clade (Selenicereus, Weberocereus and probably Aporocactus) are mostly climbing or epiphytic, and have spiny ribbed stems. The phyllocactoid clade (Epiphyllum, Disocactus, Kimnachia and Pseudorhipsalis) are mainly epiphytic, and have spineless flattened leaf-like stems. Flowers and pollination syndromes are equally diverse, ranging from large white nocturnal flowers to bright red flowers opening in the daytime.
