|discussion=<p><i>Draba sibirica</i> is one of three species of the genus in North America exhibiting malpighiaceous trichomes. It is easily distinguished from others (<i>D. malpighiacea</i> and some plants of <i>D. spectabilis</i>) by a complete absence of cauline leaves. It is found in the flora area in northeastern Greenland.</p>
