  TWENTY-NINTH

  intended 
  as 
  a 
  correction 
  of 
  that 
  mistake, 
  the 
  word 
  " 
  frequently 
  " 
  being 
  

   simply 
  an 
  additional 
  idea. 
  The 
  latter 
  appears 
  to 
  me 
  to 
  be 
  the 
  most 
  

   natural 
  interpretation. 
  He 
  does 
  not 
  mention 
  the 
  particular 
  species 
  

   in 
  either 
  case, 
  but 
  from 
  the 
  context 
  it 
  appears 
  that 
  the 
  Caladium, 
  

   real 
  or 
  supposed, 
  was 
  our 
  present 
  Peltandra 
  glauca, 
  and 
  the 
  Arum, 
  

   our 
  Peltandra 
  Virginica. 
  However 
  this 
  may 
  be, 
  the 
  fungus 
  inhab- 
  

   iting 
  the 
  latter 
  plant 
  was 
  regarded 
  as 
  Schweinitz's 
  species 
  until 
  Dr. 
  

   Howe 
  described 
  it 
  under 
  the 
  name 
  Uromyces 
  Pelta?idrm, 
  and 
  thus 
  

   indicated 
  more 
  correctly 
  its 
  generic 
  relations. 
  He 
  subsequently 
  sub- 
  

   stituted 
  the 
  specific 
  name 
  Ari- 
  Yirginici 
  for 
  Peltandroe, 
  but 
  the 
  law 
  

   of 
  priority 
  works 
  badly 
  in 
  this 
  case, 
  for 
  the 
  oldest 
  name, 
  Caladii, 
  is 
  

   manifestly 
  inappropriate 
  and 
  was 
  discarded 
  by 
  Schweinitz 
  himself, 
  

   and 
  against 
  the 
  other 
  there 
  is, 
  in 
  the 
  minds 
  of 
  some, 
  an 
  objection 
  

   because 
  of 
  its 
  compound 
  character. 
  Uromyces 
  Pontederiod 
  Ger. 
  is, 
  

   according 
  to 
  specimens 
  received 
  from 
  Mr. 
  Gerard, 
  on 
  Peltandra 
  leaves 
  

   and 
  not 
  distinct 
  from 
  U. 
  Peltandrce. 
  

  

  Until 
  recently 
  the 
  Uromyces 
  inhabiting 
  the 
  leaves 
  of 
  Ariscema 
  

   tripkyllum 
  was 
  considered 
  specifically 
  the 
  same 
  as 
  the 
  one 
  on 
  Pel- 
  

   tandra 
  leaves. 
  Dr. 
  M. 
  C. 
  Cooke 
  has 
  separated 
  a 
  form 
  of 
  this, 
  in 
  

   which 
  the 
  sori 
  are 
  clustered 
  in 
  spots, 
  under 
  the 
  name 
  Uromyces 
  

   Ariscemce. 
  I 
  am 
  satisfied 
  that 
  this 
  is 
  not 
  specifically 
  distinct 
  from 
  

   the 
  other 
  form 
  in 
  which 
  the 
  sori 
  are 
  more 
  evenly 
  scattered 
  over 
  the 
  

   whole 
  surface 
  of 
  the 
  leaf. 
  There 
  is 
  no 
  constant 
  difference 
  in 
  the 
  

   spores, 
  and 
  both 
  forms 
  manifestly 
  run 
  into 
  each 
  other 
  in 
  habit. 
  Nor 
  

   is 
  there, 
  in 
  my 
  opinion, 
  any 
  just 
  ground 
  for 
  the 
  separation 
  of 
  either 
  

   from 
  U. 
  Peltandrce 
  except 
  perhaps 
  as 
  a 
  variety, 
  for 
  the 
  only 
  appreci- 
  

   able 
  differences 
  I 
  find 
  between 
  them 
  are 
  now 
  and 
  then 
  a 
  spore 
  in 
  the 
  

   form 
  on 
  Peltandra 
  leaves 
  which 
  slightly 
  exceeds 
  in 
  size 
  any 
  that 
  I 
  

   find 
  on 
  Arissema 
  leaves 
  and 
  a 
  greater 
  tendency 
  in 
  the 
  former 
  to 
  occu- 
  

   py 
  the 
  lower 
  surface 
  of 
  the 
  leaf, 
  while 
  in 
  the 
  latter 
  there 
  seems 
  to 
  be 
  

   a 
  greater 
  tendency 
  to 
  occupy 
  the 
  upper 
  surface. 
  But 
  both 
  are 
  fre- 
  

   quently 
  amphigenous 
  in 
  habit.

  the

  All 
  our 
  species 
  of 
  Lespedezse 
  are 
  subject 
  to 
  the 
  attacks 
  of 
  this 
  

   fungus. 
  The 
  form 
  that 
  occurs 
  on 
  L. 
  capitata 
  usually 
  has 
  the 
  spores 
  

   and 
  their 
  pedicels 
  a 
  little 
  longer 
  than 
  in 
  the 
  other 
  forms 
  and 
  it 
  was 
  

   reported 
  as 
  distinct 
  under 
  the 
  name 
  U. 
  macrospora 
  B. 
  & 
  C, 
  but 
  I 
  am 
  

   now 
  satisfied 
  that 
  it 
  is 
  unworthy 
  of 
  specific 
  distinction.
