  under 
  the 
  supervision 
  

   of 
  Mr. 
  G. 
  W. 
  Oliver, 
  expert 
  propagator. 
  Numbered 
  April 
  28, 
  1910. 
  

  

  "These 
  plants 
  resulted 
  from 
  crossing 
  the 
  finger 
  lime 
  (Citrus 
  australasica) 
  with 
  the 
  

   calamondin 
  . 
  ( 
  C. 
  aurantium 
  (?)). 
  

  

  "In 
  general 
  appearance 
  the 
  seedlings 
  are 
  intermediate 
  between 
  the 
  two 
  parents. 
  

   In 
  C. 
  australasica 
  the 
  leaves 
  are 
  very 
  small, 
  the 
  petioles 
  being 
  without 
  wings. 
  In 
  

   the 
  calamondin 
  the 
  winged 
  petioles 
  are 
  quite 
  pronounced. 
  The 
  leaves 
  of 
  the 
  hybrids 
  

   are 
  much 
  larger 
  than 
  those 
  of 
  C. 
  australasica; 
  the 
  petioles 
  of 
  the 
  hybrid, 
  although 
  

   small, 
  are 
  winged. 
  The 
  seed 
  parent 
  and 
  also 
  the 
  pollen-bearing 
  parent 
  are 
  said 
  to 
  be 
  

   much 
  hardier 
  than 
  any 
  other 
  edible 
  oranges. 
  It 
  is 
  proposed 
  to 
  use 
  this 
  hybrid 
  in 
  

   future 
  crossing, 
  both 
  for 
  the 
  production 
  of 
  a 
  hardy 
  orange 
  and 
  also 
  for 
  stocks 
  for 
  the 
  

   orange 
  and 
  other 
  citrus 
  fruits 
  in 
  the 
  Gulf 
  States. 
  

  

  "The 
  seed 
  from 
  which 
  the 
  female 
  parent 
  was 
  grown 
  was 
  presented 
  to 
  Prof. 
  W. 
  M. 
  

   Hays, 
  St. 
  Anthony 
  Park, 
  Minn., 
  by 
  Mr. 
  James 
  Pink, 
  Wellington 
  Point, 
  near 
  Brisbane, 
  

   Australia; 
  this 
  seed 
  was 
  given 
  to 
  the 
  department 
  by 
  Prof. 
  Hays 
  in 
  August, 
  1905. 
  

   Mr. 
  Pink 
  says 
  of 
  this 
  species: 
  

  

  " 
  'It 
  is 
  a 
  fruit 
  which 
  I 
  think 
  capable 
  of 
  great 
  improvement. 
  Nothing 
  has 
  ever 
  been 
  

   attempted 
  with 
  it 
  here, 
  and 
  I 
  send 
  you 
  a 
  few 
  dried 
  fruits 
  which, 
  I 
  have 
  no 
  doubt, 
  

   contain 
  good 
  seeds. 
  The 
  plant 
  is 
  a 
  large 
  shrub, 
  very 
  limited 
  in 
  its 
  distribution. 
  The 
  

   fruit 
  when 
  well 
  grown 
  is 
  from 
  3 
  to 
  4 
  inches 
  long, 
  of 
  a 
  bright 
  orange-crimson 
  color, 
  and 
  

   of 
  excellent 
  flavor.' 
  

  

  "The 
  pollen-bearing 
  parent 
  was 
  received 
  as 
  Citrus 
  aurantium 
  (?) 
  by 
  the 
  Department 
  

   through 
  Messrs. 
  Lathrop 
  and 
  Fairchild 
  in 
  1899, 
  from 
  Panama. 
  It 
  is 
  said 
  to 
  have 
  

   been 
  introduced 
  into 
  Panama 
  from 
  Chile 
  by 
  Mr. 
  Gerardo 
  Lewis. 
  Mr. 
  Walter 
  T. 
  

   Swingle 
  is 
  of 
  the 
  opinion 
  that 
  it 
  is 
  the 
  calamondin 
  (Citrus 
  mitis) 
  of 
  the 
  Philippines."
