  The 
  vernacular 
  names 
  accompanying 
  the 
  British 
  Guiana 
  material 
  are 
  

   "letterwood" 
  (no. 
  598A) 
  and 
  "tibikushi" 
  {i.e., 
  bastard 
  letterwood; 
  nos. 
  

   137, 
  308, 
  467). 
  No. 
  308, 
  which 
  consists 
  only 
  of 
  comparatively 
  large 
  leaves 
  

   (about 
  11 
  cm. 
  long, 
  5.5 
  to 
  6 
  cm. 
  wide) 
  and 
  of 
  a 
  wood 
  specimen 
  (the 
  latter 
  

   not 
  examined 
  by 
  the 
  writer), 
  is 
  labeled 
  "not 
  true 
  tibikushi." 
  Although 
  

   considerably 
  larger 
  than 
  those 
  of 
  the 
  other 
  specimens 
  examined, 
  these 
  leaves 
  

   agree 
  in 
  pubescence, 
  and 
  seem 
  to 
  be 
  clearly 
  referable 
  to 
  P. 
  guianensis. 
  No. 
  

   137 
  is 
  said 
  to 
  grow 
  to 
  be 
  a 
  large 
  tree 
  on 
  sandy 
  soil, 
  the 
  bark 
  emitting 
  a 
  sticky 
  

   substance 
  when 
  cut, 
  and 
  the 
  heartwood 
  being 
  red 
  mottled 
  with 
  black. 
  

  

  The 
  material 
  from 
  Surinam 
  is 
  labeled 
  with 
  the 
  following 
  names: 
  "letter- 
  

   hout," 
  "letterhout 
  (gespikkeld)," 
  "man 
  letterhout" 
  (Dutch); 
  "manletri," 
  

   "kappewerie 
  letri" 
  (Negro 
  English); 
  "moeje-paulettoe" 
  (Saramacca 
  Bush 
  

   Negro); 
  "koereroe," 
  "kolero," 
  "koelero" 
  (Arowak 
  Indian); 
  "paida," 
  

   "toekoesipaida," 
  "wekerepaida" 
  (Carab 
  Indian)." 
  

  

  In 
  his 
  list 
  of 
  the 
  described 
  species 
  of 
  Brosimum, 
  Pittier^ 
  recognizes 
  B. 
  

   guianense 
  Huber 
  as 
  a 
  valid 
  species 
  distinct 
  from 
  Piratinera 
  guianensis 
  Aubl. 
  

   This 
  course 
  is 
  not 
  in 
  accordance 
  with 
  the 
  rules 
  of 
  nomenclature, 
  since 
  Huber 
  

   published 
  the 
  name, 
  in 
  the 
  form 
  Brosimum 
  guyanense, 
  without 
  description, 
  

   and 
  cited 
  Piratinera 
  guyanensis 
  Aubl. 
  and 
  B. 
  aubletii 
  Poepp. 
  as 
  synonyms. 
  

   Three 
  collections 
  were 
  listed, 
  nos. 
  4871, 
  9189, 
  and 
  9072. 
  The 
  two 
  latter 
  are 
  

   in 
  the 
  National 
  Herbarium, 
  as 
  mentioned 
  by 
  Mr. 
  Pittier. 
  Investigation 
  

   of 
  these, 
  in 
  the 
  light 
  of 
  the 
  information 
  recently 
  obtained 
  as 
  to 
  the 
  identity 
  

   of 
  Aublet's 
  type, 
  shows 
  that 
  no. 
  9189 
  is 
  referable 
  to 
  P. 
  guianensis 
  Aubl. 
  

   No. 
  9072, 
  however, 
  is 
  referable 
  to 
  the 
  new 
  species 
  described 
  beyond 
  as 
  Pira- 
  

   tinera 
  velutina. 
  In 
  a 
  later 
  note 
  by 
  Huber, 
  ^'^ 
  cited 
  by 
  Pittier 
  as 
  the 
  place 
  of 
  

   publication 
  of 
  B. 
  guianense, 
  where 
  the 
  wood 
  is 
  described 
  (with 
  the 
  vernacular 
  

   name 
  given 
  as 
  "muirapinima"), 
  reference 
  is 
  again 
  made 
  to 
  P. 
  guianensis 
  

   Aubl.

  Prof. 
  Record, 
  

   who 
  has 
  studied 
  wood 
  material 
  collected 
  by 
  Mr. 
  Pittier, 
  informs 
  me 
  that 
  the 
  

   sapwood 
  is 
  white, 
  and 
  the 
  heartwood 
  dark 
  red 
  with 
  black 
  markings.
