  some 
  of 
  the 
  fruit 
  without 
  pressing. 
  It 
  is 
  important 
  that 
  the 
  

   three 
  collections 
  be 
  made 
  from 
  the 
  same 
  tree 
  or 
  shrub 
  in 
  order 
  to 
  

   avoid 
  the 
  danger 
  of 
  confusing 
  two 
  or 
  more 
  closely 
  related 
  species. 
  

   Sometimes 
  two 
  or 
  more 
  species 
  grow 
  together 
  in 
  one 
  clump 
  and 
  

   in 
  such 
  cases 
  special 
  care 
  is 
  necessary 
  lest 
  the 
  intermingled 
  

   branches 
  lead 
  to 
  inextricable 
  confusion 
  of 
  species. 
  To 
  guard 
  

   against 
  any 
  slip 
  of 
  memory 
  it 
  is 
  well 
  to 
  mark 
  the 
  trunk 
  of 
  every 
  

   tree 
  or 
  shrub 
  from 
  which 
  specimens 
  are 
  taken, 
  giving 
  to 
  each 
  a 
  

   number 
  corresponding 
  to 
  a 
  number 
  attached 
  to 
  the 
  specimens 
  

   taken 
  from 
  it. 
  With 
  a 
  pocket 
  knife 
  shave 
  the 
  rough 
  bark 
  from 
  a 
  

   small 
  place 
  on 
  one 
  side 
  of 
  the 
  trunk 
  and 
  inscribe 
  the 
  number 
  on 
  

   this 
  smooth 
  place. 
  It 
  is 
  well 
  in 
  every 
  case 
  to 
  select 
  the 
  same 
  side 
  

   of 
  the 
  trunk, 
  for 
  example, 
  the 
  north 
  side. 
  Then 
  no 
  time 
  need 
  be 
  

   lost 
  in 
  looking 
  for 
  the 
  mark 
  on 
  the 
  other 
  sides. 
  

  

  Because 
  the 
  branches 
  are 
  often 
  coarse 
  and 
  crooked 
  and 
  armed 
  

   with 
  stout 
  spines, 
  strong 
  pressure 
  is 
  necessary 
  to 
  make 
  good 
  

   herbarium 
  specimens 
  of 
  them. 
  A 
  screw 
  press 
  is 
  recommended 
  for 
  

   this 
  purpose. 
  It 
  is 
  also 
  well 
  to 
  loosen 
  the 
  spines 
  by 
  partly 
  split- 
  

   ting 
  them 
  from 
  the 
  branch 
  before 
  putting 
  the 
  samples 
  in 
  press. 
  

   It 
  is 
  desirable 
  to 
  know 
  the 
  date 
  of 
  each 
  collection. 
  It 
  should 
  

   therefore 
  be 
  recorded 
  on 
  the 
  ticket. 
  

  

  PRUINOSAE 
  

  

  Fruit 
  medium, 
  red 
  when 
  ripe, 
  pruinose; 
  stamens 
  10-20; 
  leaves 
  

   thick 
  or 
  subcoriaeeous, 
  commonly 
  bluish 
  green, 
  glabrous 
  when 
  

   mature. 
  

  

  The 
  pruinosity 
  of 
  the 
  unripe 
  fruit 
  is 
  one 
  of 
  the 
  most 
  available 
  

   characters 
  by 
  which 
  to 
  recognize 
  the 
  species 
  of 
  this 
  group. 
  The 
  

   two 
  species 
  here 
  described 
  differ 
  in 
  the 
  number 
  of 
  their 
  stamens 
  

   and 
  the 
  color 
  of 
  their 
  anthers.
