Notes and lectotypification of names based on Brazilian collections of Prince Maximilian of Wied

In the course of reconstructing the Brazilian herbarium of Prince Maximilian of Wied, several species were found in the literature which need either correction or clarification. Problems include priority considerations, authority of species names, conflicting typifications and other errors. This paper reports 12 currently accepted species collected by Prince Maximilian in Brazil, commenting on their taxonomic status and nomenclature. Included are type specimens of Andromeda ambigua Schrad. (lecto and isolectotypes; = Agarista revoluta (Spreng.) Hook. f. ex Nied.), Andromeda crassifolia Nees (lecto and isolectotypes; = Agarista revoluta), Aphelandra marginata Nees & Mart. (lecto and isolectotypes), Aphelandra maximiliana (Nees) Benth. (lecto and isolectotypes), Ceiba ventricosa (Nees & Mart.) Ravenna (lectotype), Cinnamodendron axillare (Nees) Endl. ex Walp. (lecto and isolectotypes), Croton gnaphaloides Schrad. (lecto and isolectotype), C. klaenzei Müll. Arg. (holotype), Geissomeria nitida (Nees & Mart.) Nees & Mart. (lecto and isolectotypes), Nectandra squarrosa Nees var. pyrifolia Nees (lecto and isolectotypes; = Ocotea squarrosa (Nees) Mez), Ocotea squarrosa (lecto and isolectotypes), Pavonia semiserrata (Schrad.) Steud. (lecto and isolectotypes), Stenandrium serpens Nees (lecto and isolectotypes), Zollernia falcata Wied-Neuw. & Nees (lecto and isolectotypes; = Z. glabra (Spreng.) Yakovlev) and Z. splendens Wied-Neuw. & Nees (lectotype; = Z. glabra). Additionally, a new name, Aphelandra verrugensis P. L. R. Moraes, is proposed to replace Synandra amoena Schrad., which is the oldest name of the taxon currently known as Aphelandra ignea Nees.
