  or 
  the

  at 
  the

  with 
  4

  larger 
  segments 
  in 
  general 
  

   broadly 
  cuneate 
  or 
  cuneate-rhombic, 
  5 
  to 
  8 
  mm.

  3 
  to 
  5 
  mm. 
  broad 
  

   (the 
  base 
  as 
  broad 
  as 
  the 
  common 
  wing), 
  obliquely 
  cleft 
  into 
  2 
  or 
  3 
  lobes, 
  

   these 
  simple 
  or 
  shallowly

  at 
  tip; 
  ultimate 
  lobes 
  1.7

  the 
  hairs 
  

   of 
  the

  side 
  whitish, 
  spreading, 
  often 
  gland-tipped, 
  borne 
  mainly 
  on

  venation

  the

   tips 
  of

  A 
  close 
  ally 
  of 
  P 
  silo 
  gramme 
  chiapensis 
  Maxon,^ 
  of 
  Mexico, 
  belonging 
  to 
  

   the 
  group 
  of 
  P. 
  hirta 
  and 
  P. 
  glandulosa, 
  of 
  South 
  America. 
  That 
  species 
  

   is 
  similar 
  to 
  P. 
  cuhensis 
  in 
  structure, 
  but 
  differs 
  in 
  its 
  much 
  smaller 
  pinnules 
  

   and 
  narrower 
  segments 
  (the 
  ultimate 
  lobes 
  mostly 
  1 
  mm. 
  broad, 
  or 
  less), 
  

   and 
  in 
  its 
  more 
  copious 
  hairy 
  covering, 
  this 
  largely 
  of 
  a 
  distinctly 
  glandular 
  

   type.

  Near 
  Pico 
  Turquino 
  (11126). 
  

  

  Apparently 
  new 
  to 
  Cuba. 
  It 
  occurs 
  on 
  the 
  summit 
  of 
  Blue 
  Mountain 
  

   Peak, 
  Jamaica, 
  altitude 
  2,225 
  meters,

  Slopes

  at 
  1,800 
  to 
  1,900 
  meters 
  altitude 
  (11148). 
  

  

  Originally 
  described 
  from 
  much 
  smaller 
  specimens, 
  collected 
  at 
  Camp 
  La 
  

   Gloria, 
  south 
  of 
  Sierra 
  Moa, 
  Oriente, 
  Cuba, 
  by 
  J. 
  A. 
  Shafer 
  (no. 
  8106). 
  The 
  

   present 
  specimens 
  are 
  about 
  1 
  meter 
  high 
  and 
  apparently 
  represent 
  a 
  full 
  

   development 
  of 
  the 
  species. 
  The 
  sterile 
  blade 
  tapers 
  gradually 
  in 
  the 
  lower 
  

   third, 
  the 
  lowermost 
  pinnae 
  being 
  less 
  than 
  1 
  mm. 
  long. 
  In 
  other 
  respects 
  

   the 
  plant 
  agrees 
  with 
  the 
  original 
  material, 
  the 
  form 
  of 
  the 
  sterile 
  pinnae 
  

   being 
  especially 
  distinctive.

   at 
  elevations 
  of
