  Dioicous: 
  plants 
  mostly 
  of 
  medium 
  size, 
  growing 
  In 
  compact 
  

   tufts 
  with 
  erect, 
  often 
  dichotomous 
  stems, 
  radiculose 
  at 
  the 
  base. 
  

   Stem-leaves 
  when 
  dry 
  mostly 
  strongly 
  incurved 
  or 
  crispate 
  and 
  

   subtubulose 
  above 
  the 
  erect, 
  clasping,

  stout, 
  vanishing 
  

  

  just 
  below 
  the

  or 
  more 
  or 
  less 
  excurrent, 
  often 
  enlarged 
  and 
  

   bearing 
  propagula 
  in 
  dense 
  clusters 
  at 
  the 
  apex, 
  from 
  smooth 
  to 
  

   rough 
  on 
  both 
  sides, 
  sometimes 
  spinose, 
  in 
  cross-section 
  showing 
  

   from 
  one 
  to 
  three 
  rows 
  of 
  guide-cells 
  with 
  stereid 
  bands 
  above 
  and 
  

   below 
  and 
  outer 
  cells 
  mostly 
  dififerentiated. 
  Leaf-margin 
  usually 
  

   more 
  or 
  less

  serrate 
  or 
  sometimes 
  with 
  two 
  serrate 
  

   wings- 
  Ribbon-like 
  bands 
  of 
  green, 
  elongate 
  cells 
  (teniolae), 
  

   occasionally 
  wanting, 
  extend 
  just 
  within 
  the 
  margin 
  from 
  base

  a
