Abstract

Tanaecium is a genus of Neotropical lianas that includes many species with long white corollas pollinated by hawkmoths. The type of the genus is T. jaroba. Even though records of T. jaroba from Jamaica and Brazil were cited in the protologue, no corresponding specimens have been found. An illustration of T. jaroba constitutes the only original material located and has been designated as its lectotype. However, the plate of T. jaroba does not include sufficient characters to properly identify this species. We present a historical overview on the nomenclature and taxonomic history of Tanaecium and designate an epitype for T. jaroba, allowing for the accurate identification of this species. We also designate a lectotype for T. praelongum, a synonym of T. jaroba. (AU)
