   All 
  the

  mature

  This 
  variety 
  is 
  

   easily 
  recognized 
  by 
  its 
  remarkable 
  kinky 
  wool, 
  occuring 
  especially 
  upon 
  

   the 
  lower 
  leaf-surfaces 
  and 
  branchlets, 
  but 
  often 
  also 
  upon 
  the 
  upper 
  leaf- 
  

   surfaces. 
  The 
  bracts 
  show 
  great 
  variation, 
  the 
  foliaceous 
  forms 
  being 
  con- 
  

   hned 
  chiefly 
  to 
  the 
  fertile 
  aments.
