--><p>Several species of <i>Plumbago</i> are cultivated, including <i>P. auriculata</i>. The entire plant of that species, especially the root, contains plumbagin, a toxic naphthoquinone derivative (oil of plumbago), which may cause severe skin irritation or blistering in humans and may also be toxic to other animals (T. C. Fuller and E. McClintock 1986).</p><!--
--><p>The remarkable glands on the calyces of <i>Plumbago</i> are often called “glandular hairs,” but they are not true hairs, being much more massive and multicellular structures with enlarged, capitate apices.</p>
