Dieffenbachia

Commonly known as: Dumb Cane

All parts of this plant contain raphides; crystalline, needle-like structures which are ejected when cell walls are damaged. It's a defense mechanism against animals, and it can cause stinging and burning to the mouth. Hence the name, dumb cane. It's one of the best varieties for purifying indoor air and is easy to care for.
