Data are given on the taxonomy and nomenclature of 115 Rhenish Rubus taxa, originally described and published between 1878 and 1935. The identity of many of the 86 taxa described by Braeucker, however, remains obscure since his herbarium was destroyed in Berlin during World War II. Doublette material in other herbaria made the clarification of 16 of Braeucker's names possible, eight of which are lectotypified here. 20 of the 29 names of Rhenish Rubus taxa published by Ade, Braun, Kükenthal and Schumacher are clarified, 14 are lectotypified. A detailed description and illustration of Rubus erythrocomos, a little known regional species from North Rhine-Westphalia and the Rhineland-Palatinate described by G. Braun, are provided for the first time.
