Amianthium

Amianthium is a genus of perennial plants growing from bulbs. It contains one species, Amianthium muscitoxicum, known in English as fly poison from a literal translation of the Latin muscitoxicum, is noted for its pretty flowers and its toxic alkaloid content. While all parts of the plant are poisonous, the bulb is particularly toxic. The scientific name was given to it by Thomas Walter when he published his Flora Caroliniana in 1788.
