  FAMILY 
  

  

  Grass-like 
  or 
  rush-like 
  herbs, 
  with 
  solid, 
  usually 
  triangular, 
  

   stems, 
  growing 
  in 
  tufts. 
  The 
  sheathing 
  base 
  of 
  the 
  generally 
  

   3-ranked 
  leaves, 
  when 
  present, 
  is 
  not 
  slit 
  as 
  in 
  grasses. 
  The 
  

   flowers 
  are 
  usually 
  somewhat 
  less 
  inclosed 
  by 
  bracts 
  than 
  

   those 
  of 
  grasses 
  ; 
  the 
  perianth 
  is 
  absent 
  or 
  rudimentary 
  ; 
  

   stamens 
  generally 
  3; 
  style 
  2-cleft 
  or 
  3-cleft.
