Rhizome




















         The ocotillo plant (top) immediately sheds its
          small leaves as water sources decline. It re-
       mains in hibernation until it rains. Some bushes
       live on water and nutrients stored in special tis-
         sues (rhizomes), which are stems that extend
         below the soil like horizontal roots. (top right)
          Plants such as the iris (below) and anemone
               (right) possess structures of that kind.
