  a 
  new 
  species, 
  designating 
  the 
  "Arizona** 
  specimen 
  as 
  the 
  type 
  

   and 
  applying

  accepted 
  and 
  accredited 
  to 
  him. 
  I 
  at 
  

   first 
  readily 
  accepted 
  Professor

  separation 
  as

  species; 
  but 
  as 
  my 
  studies 
  continued 
  and 
  my 
  conception 
  of 
  L. 
  

   sparsifloruSy 
  sejisic 
  lato, 
  developed, 
  I 
  was 
  forced 
  to 
  acknowledge 
  

   the 
  very 
  close 
  relationship 
  of 
  this 
  new 
  form 
  to 
  the 
  typical 
  L. 
  

   sparsiflorus. 
  Intermediates 
  connect 
  it 
  with 
  at 
  least 
  three 
  of 
  the 
  

   varieties 
  here 
  recognized.
