Differs from Arabis alpine L., an European and N. Asian species, primarily by its more sturdy plants, without stolons, narrow cauline leaves with obtuse minute auricles and less hairy or glabeous sepals. Also differs from Arabis bijuga Watt with which it may sometimes be confused by its smaller flowers and erect siliquae, and often minutely auricled leaf bases.
