  _ 
  Montana, 
  collected 
  by 
  Mr. 
  Robert 
  S. 
  Williams 
  in 
  the 
  

  

  , 
  July, 
  1882, 
  in 
  the 
  H 
  

   m 
  Lower 
  Belt 
  Park 
  in 
  1889. 
  

  

  This 
  IS 
  a 
  slenderer 
  plant 
  than 
  H. 
  cylindrica, 
  and 
  has 
  

   more 
  entire 
  leaves 
  and 
  more 
  distant 
  flowers 
  than 
  either 
  that 
  

   species 
  or 
  H. 
  bracteata 
  or 
  H. 
  Hallii. 
  It 
  has 
  somewhat 
  the 
  

   look 
  of 
  a 
  Telhma, 
  to 
  which 
  genus 
  I 
  at 
  first 
  referred 
  it, 
  but 
  as 
  

   the 
  petals 
  are 
  entire 
  and 
  the 
  stamens 
  uniformly 
  five, 
  it 
  comes 
  

   lairly 
  vvithm 
  the 
  definition 
  of 
  Heuchera, 
  even 
  though 
  the 
  

   ripened 
  capsule 
  protrudes 
  a 
  little 
  beyond 
  the 
  lobes 
  of 
  the 
  

   calyx. 
  Mr. 
  Canby 
  informs 
  me 
  that 
  he 
  has 
  specimens 
  col- 
  

  

  ^cted 
  by 
  himself 
  at 
  Nevada 
  creek 
  in 
  1883, 
  and 
  others 
  from 
  

   Boseman 
  collected 
  by 
  Prof 
  Scribner, 
  and 
  others 
  again 
  from 
  

   Jefferson 
  City, 
  Yellowstone 
  Park 
  and 
  Beaver 
  Head 
  Co.

  to 
  the 
  Gray 
  Herbarium, 
  with 
  the 
  MSS. 
  name 
  of 
  Tellima 
  pen- 
  

   tandra; 
  but 
  as 
  the 
  vvhole 
  genus 
  Heuchera 
  is 
  normally 
  pen- 
  

  

  tandvous, 
  and 
  as 
  Mr. 
  W 
  

  

  to 
  have 
  been 
  the 
  

  

  eaihest 
  collector 
  of 
  the 
  plant, 
  he 
  kindly 
  writes 
  that 
  he 
  can 
  

   see 
  no 
  possible 
  objection 
  to 
  the 
  name 
  here 
  proposed. 
  Mr. 
  

   W 
  11 
  ams 
  resides 
  at 
  Great 
  Palls, 
  Montana, 
  and 
  has 
  devoted 
  

   much 
  time 
  to 
  the 
  study 
  of 
  tjie 
  flora 
  of 
  the 
  neighboring 
  region 
  ; 
  

   and 
  It 
  IS 
  with 
  great 
  pleasure 
  that 
  I 
  find 
  an 
  opportunity 
  of 
  

   nammg 
  a 
  Montana 
  plant 
  in 
  his 
  honor.
