  Legume 
  lanceolate, 
  long-stipitate, 
  attenuate 
  at 
  the 
  base, 
  acute 
  at 
  the 
  apex, 
  

   glabrous, 
  lustrous, 
  1-seeded 
  and 
  about 
  9 
  cm. 
  long 
  and 
  1.8 
  or 
  2 
  cm. 
  broad, 
  or 
  

   2 
  to 
  4-seeded 
  and 
  then 
  up 
  to 
  17.5 
  cm. 
  long. 
  Seeds 
  oblong-reniform, 
  not 
  

   mature. 
  

  

  Type 
  in 
  the 
  Gray 
  Herbarium, 
  collected 
  at 
  El 
  Tibor, 
  in 
  the 
  valley 
  of 
  the 
  

   Balsas 
  River 
  (between 
  the

  Like 
  D. 
  retusa 
  and 
  D. 
  hypoleuca, 
  this 
  species 
  furnishes 
  a 
  precious 
  wood, 
  

   which 
  is 
  hard, 
  fine, 
  and 
  red- 
  veined, 
  and 
  is 
  known 
  locally 
  as 
  granadillo. 
  

  

  The 
  specimens 
  at 
  hand 
  are 
  hardly 
  satisfactory 
  for 
  a 
  description, 
  but 
  they 
  

   belong 
  to 
  a 
  section 
  heretofore 
  not 
  known 
  to 
  be 
  represented 
  in 
  Mexico, 
  and 
  

   differ 
  from 
  the 
  other 
  Middle 
  American 
  species 
  of 
  the 
  group 
  in 
  the 
  shape, 
  

   consistence 
  and 
  indument 
  of 
  the 
  leaflets, 
  and 
  in 
  the 
  shape 
  and 
  appearance 
  

   of 
  the 
  pods. 
  It 
  is 
  consequently 
  pretty 
  safe 
  to 
  consider 
  them 
  as 
  correspond- 
  

   ing 
  to 
  a 
  type 
  specifically 
  distinct.

  This 
  is 
  the 
  Panama 
  "cocobola," 
  a 
  hard 
  wood 
  very 
  well 
  known 
  commercially 
  

   and 
  obtained 
  probably 
  from 
  several 
  species 
  of 
  the 
  same 
  genus. 
  I 
  have 
  seen 
  

   no 
  specimens 
  from 
  the 
  type 
  collection, 
  but 
  ours 
  agree 
  generally 
  with 
  the 
  

   description. 
  The 
  leaflets, 
  however, 
  are 
  more 
  numerous 
  and 
  not 
  usually 
  

   retuse 
  and 
  the 
  flowers 
  seem 
  to 
  be 
  smaller. 
  

  

  In 
  Panama 
  this 
  tree 
  has 
  been 
  exploited 
  with 
  such 
  diligence 
  as 
  to 
  have 
  be- 
  

   come 
  very 
  scarce 
  in 
  the 
  central 
  and 
  western 
  districts. 
  In 
  1914 
  the 
  more 
  im- 
  

   portant 
  logging 
  camps 
  were 
  at 
  Sumacate 
  and 
  Rio 
  Congo 
  in 
  Darien.
