(EQUISETUM)               
                                          
                                          
                                          
          THE PLANT         
                                          
 THE  EQUISETUM IS  A  PLANT  MUCH  OLDER 
 THAN  FERNS,  WHICH  ARE  IN  TURN  MUCH 
 OLDER THAN MOST TREES.  IT'S LIGHT GREEN 
 TO  YELLOW  IN  COLOR  AND  IS  SLIGHTLY 
               TRANSPARENT.               
                                          
 THE PLANT HAS  A SPINE. EACH VERTEBRA IS 
 STACKED  UPON THE NEXT,  WITH  SPOKELIKE 
 RIBS RADIATING OUTWARD.  EVEN  SO,  IT'S 
 VERY  LIGHT, BEING  HOLLOW. IT'S ROUGHLY 
 THE HEIGHT OF A  FOXES  TAIL, AND SHARES 
            A SIMILAR PLUMAGE.            
                                          
 IT LIKES  PARTIAL  SHADE  AND  VERY DAMP 
                  AREAS                   
                                          
                                          
                                          
          IN MAGIC          
                                          
 WHEN  A COLONY NUMBERS HIGH  ENOUGH,  IT 
 SLICES  THE  AIR   IN  THE  FOREST  INTO 
 SEPARATE  PLANES, A  FEW  CENTIMETERS IN 
 HEIGHT.  TIME   CAN  GET  DIFFRACTED  IN 
 THESE,  HITTING  EACH  IN   TURN  IN   A 
       SLIGHTLY DIFFERENT ANGLE, AND      
         EVENTUALLY SPREAD THIN.
