Lectotypification and Correct Author Citation of Ipheion uniflorum (Amaryllidaceae), with a New Synonym

The type of the generic name Ipheion Rafinesque is Milla uniflora Graham but the same specific epithet had been used in Triteleia by Lindley a few years earlier for the same species with a different type. Confusion ensued concerning the correct author citation for the species under Ipheion. A taxonomic history of the name Ipheion uniflorum (Graham) Raf., a new synonym for this species, and a lectotype for Milla uniflora are presented herein.
