  flowers, 
  as 
  is 
  the 
  case 
  with 
  those 
  found 
  here. 
  The 
  base 
  

   of 
  the 
  corolla, 
  as 
  well 
  as 
  that 
  of 
  the 
  filament, 
  is 
  copious!}' 
  

   supplied 
  with 
  long 
  hairs, 
  somewhat 
  reflexed 
  in 
  the 
  Minne- 
  

   sota 
  plants, 
  though 
  they 
  are 
  commonly 
  horizontal. 
  I 
  do 
  not 
  

   find 
  these 
  hairs 
  mentioned 
  in 
  our 
  descriptive 
  botanies, 
  nor 
  in 
  

   the 
  Synoptical 
  Flora, 
  although 
  they 
  do 
  mention 
  the 
  hairy 
  style 
  

   and 
  its 
  adaptation 
  to 
  the 
  collection 
  of 
  pollen. 
  Mention 
  is 
  

   also 
  made 
  of 
  the 
  dilated 
  bases 
  of 
  the 
  filaments. 
  Yet 
  the 
  

   hairs 
  are 
  a 
  noteworthy 
  feature 
  and 
  have 
  been 
  frequently 
  re- 
  

   ferred 
  to, 
  especially 
  in 
  connection 
  with 
  the 
  structure 
  of 
  the 
  

   flowers 
  for 
  cross 
  fertilization. 
  They 
  project 
  from 
  the 
  mar- 
  

   gins 
  of 
  filaments, 
  interlocking 
  and 
  closing 
  the 
  free 
  spaces 
  

   remaining 
  between 
  the 
  bases 
  of 
  the 
  filaments, 
  or 
  " 
  triangu- 
  

   lar 
  valves," 
  as 
  they 
  are 
  called 
  by 
  Sprengei 
  and 
  Hermann 
  

   Muller. 
  This 
  is 
  rather 
  from 
  their 
  shape 
  in 
  C. 
  rotundifolia 
  

   and 
  other 
  European 
  species, 
  for 
  in 
  C. 
  aparinoides

   hardly 
  be 
  called 
  triangular, 
  but 
  only 
  a 
  little 
  dilated.

  Hall, 
  and 
  were 
  

   mistaken 
  for 
  nectaries, 
  surrounding 
  the 
  base 
  of 
  the 
  style, 
  

   each 
  bearing 
  a 
  filament 
  at 
  its 
  top. 
  

  

  In 
  the 
  clearings 
  and 
  newly 
  cultivated 
  fields 
  Ph}'salis 
  

   grandiflora 
  attracts 
  the 
  eye 
  with 
  its 
  large 
  flowers 
  of 
  the 
  

   purest 
  white. 
  They 
  sometimes 
  measured 
  more 
  than 
  two 
  

   inches 
  across. 
  The 
  corolla 
  is 
  shallow, 
  saucer-shaped, 
  its 
  

   border 
  nearly 
  entire. 
  It 
  is 
  a 
  plant 
  w^orthy 
  of 
  cultivation 
  as 
  

   jn 
  annual, 
  though 
  it 
  has 
  one 
  disadvantage, 
  the 
  flowers 
  not 
  

   being 
  so 
  prominent 
  as 
  their 
  large 
  size 
  would 
  suggest, 
  being 
  

   somewhat 
  obscured 
  by 
  the 
  large 
  overshadowing 
  leaves.

  Spiranthes 
  gracilis 
  was 
  frequent 
  on 
  some 
  of 
  the 
  moist 
  

   hillsides, 
  partly 
  covered 
  with 
  shrubs 
  and 
  seedling 
  trees, 
  in 
  

   |he 
  partial 
  shade 
  of 
  which 
  it 
  grew. 
  It 
  had 
  one 
  peculiarity 
  a 
  

   httle 
  singular 
  to 
  my 
  experience 
  with 
  the 
  plant 
  in 
  flower, 
  since 
  

   ^.eai-ly 
  all 
  the 
  plants 
  had 
  a 
  tuft 
  of 
  fresh 
  radical 
  leaves, 
  hve 
  or 
  

   SIX 
  in 
  number. 
  As 
  generally 
  found, 
  it 
  is 
  necessary 
  to 
  looK 
  

   over 
  several 
  individuals 
  to 
  find 
  an 
  occasional 
  specimen 
  with 
  

   a 
  radical 
  leaf 
  or 
  two 
  in 
  this 
  condition 
  at 
  the 
  time 
  of 
  flowering.

  met 
  wath 
  it 
  in 
  this 
  state 
  of 
  growth 
  near 
  Whiting,

   but 
  the 
  leaves 
  were 
  not 
  so 
  manv,
