  On 
  the 
  upper 
  surface 
  of 
  the 
  leaves 
  the 
  flocci 
  form 
  minute 
  

   tufts, 
  so 
  small 
  as 
  to 
  be 
  easily 
  overlooked. 
  On 
  the 
  lower 
  surface 
  

   they 
  are 
  more 
  abundant 
  and 
  form 
  effused 
  velvety 
  patches 
  which 
  

   are 
  quite 
  conspicuous. 
  The 
  spores 
  are 
  extremely 
  abundant, 
  

   but 
  they 
  fall 
  away 
  so 
  easily 
  that 
  it 
  is 
  difficult 
  to 
  find 
  them 
  in 
  

   place.
