  Diospyros 
  conzattii 
  is 
  not 
  closely 
  related 
  to 
  any 
  of 
  the 
  species 
  previously 
  

   reported 
  from 
  Mexico, 
  with 
  the 
  possible 
  exception 
  of 
  D. 
  blepharophylla 
  

   Standi. 
  (D. 
  ciliala 
  A. 
  DC), 
  a 
  little-known 
  plant, 
  the 
  type 
  of 
  which 
  is 
  said 
  

   to 
  have 
  come 
  from 
  southern 
  Mexico. 
  That 
  is 
  described 
  as 
  having 
  ovate- 
  

   elliptic 
  ciliate 
  leaves, 
  on 
  longer 
  petioles. 
  

  

  From 
  a 
  manuscript 
  work 
  upon 
  the 
  edible 
  fruits 
  of 
  Mexico, 
  Professor 
  

   Conzatti 
  has 
  furnished 
  the 
  following 
  notes 
  concerning 
  the 
  new 
  species 
  here 
  

   described 
  : 
  

  

  "On 
  the 
  twenty-fourth 
  of 
  April, 
  1917, 
  while 
  making 
  an 
  excursion 
  in 
  the 
  

   company 
  of 
  Senor 
  E. 
  Makrinius, 
  manager 
  of 
  the 
  Cafetal 
  Concordia 
  and 
  

   its 
  subsidiaries. 
  District 
  of 
  Pochutla, 
  Oaxaca, 
  on 
  the 
  so-called 
  Cerro 
  Espino, 
  

   upon 
  which 
  lies 
  the 
  Cafetal 
  San 
  Rafael, 
  I 
  had 
  the 
  good 
  fortune 
  to 
  find 
  among 
  

   other 
  things 
  a 
  medium-sized 
  (10 
  meters) 
  tree, 
  known 
  there 
  as 
  zapote 
  negro 
  

   monies. 
  At 
  that 
  time 
  of 
  the 
  year 
  the 
  tree 
  bore 
  leaves 
  and 
  ripe 
  fruits. 
  Samp- 
  

   ling 
  the 
  fruits, 
  with 
  some 
  suspicion 
  at 
  first, 
  I 
  found 
  them 
  quite 
  to 
  my 
  taste 
  

   and 
  ate 
  as 
  many 
  as 
  I 
  could. 
  But 
  I 
  prefer 
  to 
  quote 
  what 
  I 
  have 
  already 
  

   published 
  in 
  the 
  Boleiin 
  de 
  la 
  Direccion 
  de 
  EsHidios 
  Biologicos 
  :^ 
  

  

  " 
  'The 
  zapote 
  negro 
  monies 
  is 
  especially 
  interesting 
  because 
  of 
  its 
  edible 
  

   fruit, 
  of 
  exquisite 
  flavor. 
  With 
  the 
  exception 
  of 
  the 
  chicozapote, 
  I 
  know 
  of 
  

   no 
  other 
  fruit 
  which 
  compares 
  in 
  quality 
  with 
  the 
  zapote 
  negro, 
  and 
  all 
  the 
  

   persons 
  who 
  have 
  tried 
  it 
  are 
  agreed 
  in 
  considering 
  it 
  superior 
  to 
  that. 
  The 
  

   fruits, 
  which 
  are 
  perfectly 
  round, 
  and 
  green 
  outside, 
  are 
  much 
  smaller 
  than 
  

   those 
  of 
  the 
  common 
  zapote 
  negro 
  {Diospyros 
  ebenaster), 
  being 
  only 
  4 
  cm. 
  

   in 
  diameter 
  and 
  2 
  cm. 
  or 
  slightly 
  more 
  in 
  height, 
  since 
  they 
  are 
  somewhat 
  

   depressed. 
  

  

  " 
  'It 
  seems 
  to 
  me 
  that 
  propagation 
  of 
  the 
  tree 
  should 
  be 
  relatively 
  simple, 
  

   taking 
  into 
  account 
  the 
  elevation 
  (1,000 
  meters) 
  at 
  which 
  it 
  grows 
  and 
  the 
  

   fact 
  that 
  it 
  is 
  native.'

  In 
  Christensen's 
  Index 
  Filicum 
  13 
  species 
  of 
  water 
  fernworts 
  of 
  the 
  

   genus 
  Salvinia 
  are 
  recognized, 
  these 
  mainly 
  inhabitants 
  of 
  tropical 
  

   regions. 
  Of 
  the 
  few 
  American 
  species, 
  5. 
  sprucei, 
  known 
  from 
  a 
  single 
  

   collection 
  in 
  the 
  Amazon 
  region, 
  has 
  been 
  unique 
  in 
  having 
  ascending, 
  

   somewhat 
  cup-shaped 
  leaves, 
  in 
  distinction 
  from 
  the 
  plane 
  blades 
  of 
  

   the 
  small 
  floating 
  leaves 
  of 
  other 
  species. 
  Recently 
  a 
  new 
  species 
  

   closely 
  allied 
  to 
  5. 
  sprucei 
  has 
  been 
  collected 
  in 
  Trinidad. 
  This 
  is 
  

   described 
  below.
