|discussion=<p>Plants of <i>Rhamnus davurica</i> from the flora area have sometimes been identified as subsp. nipponica (Makino) Kartesz & Gandhi [<i>R. davurica</i> var. nipponica Makino, R. nipponica (Makino) Grubov; the type from Japan] (for example, D. W. Magee and H. E. Ahles 1999), but it is not clear whether they are correctly identified or even whether they are outside the range of variability in <i></i>subsp.<i> davurica</i>.</p><!--
--><p>These plants sometimes have been called <i>Rhamnus</i> citrifolia (Weston) W. J. Hess & Stern, an illegitimate later homonym of <i>Rhamnus</i> citrifolia Rusby 1907.</p>
