--><p><i>Ecballium</i> plants are prostrate and without tendrils, and the hastiform leaves have crisped-undulate margins that appear whitish because of the light-colored abaxial surfaces. The erect peduncles are sharply nodding near the base of the fruit such that the mature fruit is pendent.</p><!--
--><p>The explosive dehiscence is stimulated by touching the peduncle near the fruit. The ripening fruit becomes turgid with mucilaginous fluid. Increasing pressure from the maturing and enlarging seeds forces the fruit to break away explosively from the plant and the seeds are ejected in a mucilaginous stream to several meters. The epithet (Greek, elaterios, driving) either reinforces the generic name or alludes to the violently purgative properties of the plant.</p>
