  collected 
  in 
  the 
  high 
  

   Sierra 
  Maestra, 
  Oriente, 
  Cuba, 
  in 
  July, 
  1922, 
  by 
  Brother 
  Leon 
  (no.

   Collected

  A 
  member 
  of 
  the 
  group 
  of 
  P. 
  momliforme 
  Lag., 
  differing 
  from 
  the 
  typical 
  

   Jamaican 
  form 
  of 
  that 
  species 
  in 
  its 
  short 
  rhizome, 
  its 
  thick, 
  short, 
  rigid 
  

   stipes, 
  its 
  numerous, 
  mostly 
  oblong 
  pinnae, 
  and 
  its 
  dark, 
  heavily 
  sclerotic 
  

   rhizome 
  scales. 
  It 
  is 
  more 
  nearly 
  related 
  to 
  continental 
  forms 
  that 
  are 
  still 
  

   erroneously 
  retained 
  in 
  P. 
  momliforme.

  Known 
  hitherto 
  only 
  from 
  the 
  original 
  collection, 
  which 
  came 
  from 
  the 
  

   Newton 
  District, 
  Port 
  Royal 
  Mountains, 
  Jamaica, 
  at 
  1,200 
  to

  meters 
  

   altitude. 
  This 
  has 
  recently 
  been 
  discussed 
  by 
  the 
  writer.^ 
  The 
  present 
  

   specimens, 
  which 
  agree 
  absolutely 
  with 
  a 
  photograph 
  of 
  the 
  type, 
  show 
  that 
  

   the 
  relationship 
  with 
  P. 
  basiattenuatum 
  Jenman 
  is 
  much 
  more 
  remote 
  than 
  

   previously 
  supposed, 
  Jenman' 
  s 
  redescription^ 
  being 
  accurate 
  in 
  every 
  respect.
