  this 
  small 
  and 
  very 
  pubescent 
  species, 
  which 
  is 
  not 
  more 
  than 
  three 
  or 
  

   four 
  inches 
  high, 
  the 
  root 
  presents 
  moniliform 
  tubers 
  and 
  sends 
  out 
  

   creeping 
  shoots, 
  the 
  leaves 
  are 
  also 
  subserrate, 
  and 
  the 
  flowers 
  very 
  

   small. 
  It 
  inhabits 
  the 
  clefts 
  of 
  rocks, 
  in 
  somewhat 
  shady 
  places.

  versicolor 
  ', 
  (3 
  ^mollis. 
  — 
  Obs. 
  This 
  variety 
  differs 
  considerably 
  

   from 
  the 
  common 
  species 
  of 
  the 
  western 
  states, 
  to 
  which 
  I 
  applied 
  the 
  

   name 
  of 
  versicolor, 
  rather 
  than 
  that 
  of 
  cordifolia, 
  given 
  to 
  it 
  by 
  Muhlen- 
  

   berg, 
  as 
  there 
  are 
  several 
  other 
  species 
  with 
  heart-shaped 
  leaves. 
  The 
  

   present 
  variety, 
  for 
  such 
  I 
  consider 
  it, 
  is, 
  like 
  the 
  original 
  species, 
  a 
  

   plant 
  of 
  rather 
  unusual 
  magnitude 
  in 
  the 
  genus, 
  every 
  where 
  softly 
  

   pubescent, 
  but 
  not 
  glandular, 
  and 
  with 
  the 
  dentations 
  of 
  the 
  leaves 
  

   rather 
  acute 
  than 
  obtuse 
  ; 
  the 
  flowers 
  are 
  also 
  larger, 
  and 
  nearly 
  of 
  a 
  

   deep 
  and 
  uniform 
  blue 
  colour.
