Abstract

Reinstatement of segregate genera and the accompanying recombinations for species in the former polyphyletic Zigadenus complex allow for a revised, practical taxonomy that defines monophyletic groups and reflects phylogenetic relationships within tribe Melanthieae (Melanthiaceae). Nine new species combinations result from recircumscription of Zigadenus Michaux and Stenanthium (A. Gray) Kunth and from recognition of Anticlea Kunth and Toxicoscordion Rydberg. The genus Stenanthella Rydberg and the basionyms for Stenanthium leimanthoides (A. Gray) Zomlefer & Judd (Amianthium leimanthoides A. Gray) and Anticlea sachalinensis (F. Schmidt) Zomlefer & Judd (Stenanthium sachalinense F. Schmidt) are lectotypified.
