title: The correct name in Oenothera for Gauradrummondii (Onagraceae).
abstract: In 2007, Wagner and Hoch proposed the new name Oenotheraxenogaura W.L.Wagner & Hoch for the species then known as Gauradrummondii (Spach) Torrey & A. Gray (non Oenotheradrummondii Hooker, 1834). However, the authors overlooked the availability of Gaurahispida Bentham (1840) for this species. Accordingly, we herewith make the appropriate new combination for this species, Oenotherahispida (Bentham) W.L.Wagner, Hoch & Zarucchi, and place Oenotheraxenogaura in synonymy.
