Abstract
The correct nomenclature and differences between Draba adamsii Ledebour (n = 16), D. oblongata R.Br. ex DC. (n = 32), and D. corymbosa R.Br. ex DC. (n = 72) are given. Plants previously referred to as D. oblongata, D. micropetala, and D. leptopetala should be named D. adamsii Ledebour. The earliest legitimate name for another taxon is D. oblongata R.Br. ex DC. not D. groenlandica E. Ekman. The third taxon should be referred to as D. corymbosa R.Br. ex DC. rather than D. bellii Holm or D. macrocarpa Adams.
