--><p><i>Dasylirion</i> was once a major food source in the desert southwest. The bulbs were roasted in rock-lined pits and pounded into cakes. A potent alcoholic beverage, known as “sotol,” is distilled from the baked and fermented bulbs. Leaves of <i>Dasylirion</i> are widely used to weave baskets.</p><!--
