|discussion=<p><i>Ziziphus divaricata</i> usually has been regarded as <i>Z. obtusifolia</i> <i></i>var.<i> canescens</i>, but <i>Z. divaricata</i> and <i>Z. obtusifolia</i> are discontinuously distinct morphologically and geographically. Although it seems clear that they have a sister relationship, treatment of each at specific rank emphasizes their apparent evolutionary independence.</p>
