Nomenclatural and taxonomic notes on Rubus davidianus Kuntze and R. viburnifolius Franch

Critical examinations of specimens, with literature reviews, have shown that Rubusdavidianus is conspecific with R.lambertianus. Therefore, we treat R.davidianus as a new synonym within Rubus. We propose a new name, Rubusloirensis Ti R. Huang nom. nov. to replace the later homonym of R.pycnanthus Genev. Additionally, lectotypification of three names, R.davidianus Kuntze, R.malifolius Focke and R.viburnifolius Franch., are designated here after examination of previous works.
