  Shaly 
  soil 
  near 
  Lansingburg. 
  Flowers 
  open 
  about 
  the 
  middle 
  

   of 
  Ma}', 
  fruit 
  ripens 
  early 
  in 
  September 
  and 
  soon 
  falls. 
  In 
  our 
  

   plants 
  the 
  flowers 
  open 
  and 
  the 
  fruit 
  ripens 
  two 
  or 
  three 
  weeks 
  

   earlier 
  than 
  in 
  the 
  type 
  and 
  the 
  number 
  of 
  stamens 
  ranges 
  from 
  

   12-19. 
  In 
  no 
  case 
  have 
  I 
  found 
  a 
  fl'ower 
  with 
  20 
  stamens. 
  Never- 
  

   theless 
  these 
  variations 
  do 
  not 
  seem 
  to 
  be 
  of 
  sufficient 
  importance 
  

   to 
  warrant 
  a 
  separation 
  of 
  the 
  plants. 
  The 
  unfolding 
  leaves 
  are 
  

   tinged 
  with 
  brownish 
  red.
