  This 
  species, 
  though 
  subject 
  to 
  much 
  variation, 
  is 
  easily 
  separable 
  

   from 
  all 
  others. 
  The 
  forms 
  which 
  authors 
  have 
  named 
  as 
  species 
  are 
  

   scarcely 
  varieties, 
  but 
  denote 
  differences 
  in 
  age 
  and 
  development.
