Epipremnum is a genus of flowering plants in the family Araceae, found in tropical forests from China, the Himalayas, and Southeast Asia to Australia the western Pacific. They are evergreen perennial vines climbing with the aid of aerial roots. They may be confused with other Monstereae such as Rhaphidophora, Scindapsus and Amydrium.

Raphides are needle-shaped crystals of calcium oxalate monohydrate or calcium carbonate as aragonite, found in more than 200 families of plants. Both ends are needle-like, but raphides tend to be blunt at one end and sharp at the other.
