Notes on the lecotypification of Nectandra sanguinea, the type of Nectandra, are presented, complementing the prior one proposed by Luciano Bernardi. This is necessary in order to clarify the confusion that arose after his analysis whereby the sheet designated by him as “holotypus” was subsequently altered, and because he mixed elements of two different sheets in the photographic plate indicated as being a single sheet of the “holotypus.” Corrections of authorship and the place and date of publication of the species name are also discussed, having been overlooked by most authors who were seemingly unaware of the existence of the original dissertation published by Rottbøll in 1776.
