|discussion=<p>The illegitimate name <i>Berberis trifoliolata</i> Moricand <i></i>var.<i> glauca</i> (I. M. Johnston) M. C. Johnston has been used for plants with very strongly glaucous leaves. Weakly and strongly glaucous plants are often found in the same population, however, indicating that they are not distinct varieties.</p><!--
--><p><i>Berberis trifoliolata</i> is susceptible to infection by Puccinia graminis.</p>
