Numerous, see text Rhipsalis is a genus of epiphytic flowering plants in the cactus family, typically known as mistletoe cacti.

The scientific name Rhipsalis derives from the Ancient Greek term for wickerwork,[2][3] referring to the plants' morphology.

The flowers are borne lateral or apical and are actinomorphic with a varying number of perianth segments, stamens and carpels.

In the taxonomic treatment in The New Cactus Lexicon, 35 species were accepted, divided into five subgenera (Phyllarthrorhipsalis, Rhipsalis, Epallagogonium, Calamorhipsalis, Erythrorhipsalis).

[1] Species accepted by Plants of the World Online as of January 2023[update] are listed below,[8] with subgeneric placements, where given, based on Calvente (2012).

[1] Rhipsalis is found as pendulous epiphyte in tropical rainforests, some species may also grow epilithic or, rarely, terrestrial.
