Peer reviewed, Journal article
MetadataShow full item record
The first typification of Lepra Scop. by Pertusaria discoidea (Pers.) Malme (= Lepra albescens (Hudson) Hafellner), made in the Paris Code (1956), is shown to be correct after studies of the original material in the Micheli Herbarium in FI. Details of the latter are given. All later statements about this case, even in the Code , are irrelevant.
