  but 
  

   ours 
  almost 
  certainly 
  belong 
  in 
  the

  Celastrus 
  and 
  I 
  have 
  

   thought 
  it 
  best 
  to 
  consider 
  them 
  as 
  a 
  distinct 
  species.

   This 
  little 
  leaf 
  appears 
  undoubtedly 
  to 
  belong 
  to 
  the 
  above 
  

   species, 
  although 
  it 
  might 
  almost 
  equally 
  well 
  be 
  compared 
  with 
  

   the 
  leaf 
  figured

  Its 
  identity 
  with 
  the

  Sapindns, 
  

   however, 
  is 
  much 
  closer 
  than 
  with 
  Ouercus.

  In 
  referring 
  our 
  specimen 
  provisionally 
  to 
  this 
  species 
  I 
  have 
  

   followed 
  the 
  example 
  of 
  Lesquereux, 
  who 
  also 
  questioned 
  the 
  

   reference 
  of 
  his 
  specimens 
  to 
  the 
  species. 
  There 
  can 
  be 
  but 
  

   little 
  doubt, 
  however, 
  that 
  ours 
  is 
  identical 
  with 
  the 
  one 
  figured

  Lesquereux
