  considers 
  It 
  to 
  be 
  dioicous; 
  he 
  retains 
  It 
  under 
  Calymperes 
  although 
  

   describing 
  a 
  peristome 
  of 
  sixteen 
  teeth 
  that 
  hardly 
  project 
  above 
  

   the 
  rim 
  of 
  the 
  capsule, 
  a 
  pale, 
  narrow 
  border 
  as 
  In 
  Syrrholodon 
  

   and 
  a 
  calyptra 
  split 
  on 
  one 
  side 
  ; 
  a 
  sterile 
  specimen 
  is 
  also 
  mentioned 
  

   as 
  bearing 
  filiform 
  propagula 
  as 
  In 
  the 
  recent 
  collections; 
  the 
  lid 
  

   is 
  said 
  to 
  be 
  subulate 
  and 
  as 
  long 
  as 
  the 
  capsule, 
  but 
  both 
  

   mature 
  lids 
  and 
  calyptras 
  seem 
  to 
  be 
  unknown 
  in 
  any 
  available 
  

   collection.

   one

  cross-section 
  somewhat 
  semiterete, 
  with 
  six 
  or 
  seven 
  

   guide-cells, 
  stereid

  below 
  them

  below, 
  composed 
  of 
  a 
  

   pale, 
  cylindric 
  band 
  of 
  elongate, 
  stereid 
  cells; 
  cells 
  of 
  blade 
  pellucid, 
  

   mostly 
  slightly 
  elongate, 
  somewhat 
  angular, 
  the 
  median 
  7-8

  8-10

   leaf

  the

  very 
  acute

  Distribution:

  This 
  species 
  Is 
  neariy 
  related, 
  by 
  the 
  position 
  of 
  the 
  propagula 
  

   and 
  shape 
  of 
  leaf, 
  to 
  S. 
  parasiticus, 
  but 
  the 
  latter 
  is 
  a 
  larger 
  plant 
  

   with 
  much 
  wider 
  leaves 
  and 
  costa.
