Anticlea is a genus of flowering plants in the family Melanthiaceae, tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in number of changes to placements within this tribe. Anticlea was long submerged into the genus Zigadenus; however its separate position has been confirmed. Some species were also moved from Stenanthium into Anticlea. (See also Phylogeny of Melanthieae.) Members of Anticlea may also be distinguished from other members of the former genus Zigadenus, the deathcamases, by the presence of narrow tepals with a single, conspicuous, bilobed gland. It also has a wider distribution, occurring in Asia and much of North and Central America, ranging south to Guatemala.
