  berry 
  rust, 
  Oceoma 
  nit 
  ens, 
  both 
  in 
  the 
  dewberry 
  and 
  the 
  black- 
  

   berry. 
  Plants 
  badly 
  infested 
  by 
  this 
  rust 
  are 
  generally 
  destitute 
  

  

  of 
  prickles. 
  

  

  Hubus

  This 
  northern 
  species 
  occurs 
  in. 
  the 
  open 
  region 
  known 
  as 
  "The 
  

  

  Plains." 
  This 
  is 
  in 
  the 
  southern 
  part 
  of 
  St. 
  Lawrence 
  county 
  

  

  near 
  the 
  headwaters 
  of 
  the 
  Oswegatchie 
  river.

  Plains. 
  The 
  plants 
  were 
  not

  in 
  flower 
  early

  The 
  variability 
  of 
  our 
  native 
  roses 
  is 
  the 
  source 
  of 
  considerable 
  

   difficulty 
  and 
  perplexity 
  in 
  their 
  classification. 
  In 
  the 
  last 
  edition 
  

   of 
  the 
  Manual 
  this 
  species 
  is 
  said 
  to 
  have 
  no 
  infrastipular 
  spines, 
  

   yet 
  in 
  a 
  specimen 
  collected 
  at 
  Cooperstown 
  Junction 
  these 
  are 
  

   plainly 
  present. 
  The 
  stipules 
  are 
  described 
  as 
  dilated, 
  but 
  in 
  

   another 
  specimen 
  from 
  the 
  same 
  locality, 
  they 
  are 
  very 
  narrow. 
  

   The 
  fruit 
  is 
  described 
  as 
  globose, 
  but 
  in 
  specimens 
  collected 
  at 
  

   Thompson's 
  lake, 
  the 
  fruit 
  is 
  pointed 
  at 
  the 
  base 
  and 
  somewhat 
  

   pyriform. 
  In 
  these 
  specimens 
  also 
  the 
  stipules 
  are 
  very 
  narrow, 
  

   even 
  on 
  young 
  shoots.

  Saxifraga 
  aizoides 
  L. 
  

  

  Nearly 
  thirty 
  years 
  ago 
  this 
  plant 
  and 
  its 
  companion, 
  Primula 
  

   Mistassinica, 
  were 
  discovered 
  by 
  Kev. 
  J. 
  A. 
  Paine 
  on 
  the 
  wet 
  and 
  

   dripping 
  precipices 
  that 
  iie 
  along 
  Fish 
  creek, 
  above 
  Taberg. 
  Both 
  

   these 
  plants 
  are 
  still 
  abundant 
  in 
  that 
  locality, 
  and 
  the 
  nature 
  of 
  

   the 
  place 
  is 
  such 
  that 
  nothing 
  but 
  the 
  greed 
  of 
  botanists 
  is 
  likely 
  

   soon 
  to 
  exterminate 
  them. 
  The 
  yellow 
  saxifrage 
  is 
  especially 
  lux- 
  

   uriant, 
  and 
  often 
  exceeds 
  the 
  dimensions 
  attributed 
  to 
  it 
  in 
  the 
  

   Manual. 
  It 
  is 
  in 
  flower 
  when 
  the 
  primula 
  is 
  developing 
  its 
  fruit. 
  

  

  Drosera 
  rotundifolia 
  L. 
  

  

  This 
  pretty 
  little 
  sundew 
  is 
  common 
  in 
  the 
  Adirondack 
  region. 
  

   A 
  favorite 
  habitat 
  of 
  it 
  is 
  on 
  decaying 
  trunks 
  of 
  trees 
  lying 
  in 
  

   the 
  water 
  of 
  lakes 
  and 
  ponds.
