Epiphyllum chrysocardium (syn.

: Selenicereus chrysocardium) is an epiphytic cactus native to Mexico,[3] commonly called fern leaf cactus, golden heart epiphyllum, shark tooth cactus and shark fin cactus.

It used to be the only species in the genus Chiapasophyllum, in addition to a former inclusion in the genus Selenicereus (commonly referred to as the fishbone, ric-rac or zig-zag cacti), but molecular phylogenetic studies show that it belongs to Epiphyllum.
