  Retrograde 
  Varieties 
  

  

  ophyllous 
  variety 
  of 
  the 
  strawberry 
  and 
  many 
  

   other 
  forms 
  will 
  be 
  discussed 
  later. 
  

  

  To 
  enlarge 
  this 
  list 
  it 
  would 
  only 
  be 
  necessary 
  

   to 
  extract 
  from 
  a 
  flora, 
  or 
  from 
  a 
  catalogue 
  of 
  

   horticultural 
  plants, 
  the 
  names 
  of 
  the 
  varieties 
  

   enumerated 
  therein. 
  In 
  nearly 
  every 
  instance, 
  

   where 
  true 
  varieties 
  and 
  not 
  elementary 
  species 
  

   are 
  concerned, 
  a 
  single 
  term 
  expresses 
  the 
  

   whole 
  character. 
  

  

  Such 
  a 
  list 
  would 
  also 
  serve 
  to 
  illustrate 
  the 
  

   second 
  point 
  since 
  the 
  same 
  names 
  would 
  recur 
  

   frequently. 
  Long 
  lists 
  of 
  varieties 
  are 
  called 
  

   alba, 
  or 
  inermis, 
  or 
  canescens 
  or 
  lutea, 
  and 
  

   many 
  genera 
  contain 
  the 
  same 
  appellations. 
  In 
  

   some 
  instances 
  the 
  systematists 
  use 
  a 
  diversity 
  

   of 
  names 
  to 
  convey 
  exactly 
  the 
  same 
  idea, 
  as 
  if 
  

   to 
  conceal 
  the 
  monotony 
  of 
  the 
  character, 
  as 
  

   for 
  instance 
  in 
  the 
  case 
  of 
  the 
  lack 
  of 
  hairs, 
  

   which 
  is 
  expressed 
  by 
  the 
  varietal 
  names 
  of 
  

   Papaver 
  dubium 
  glob 
  rum, 
  Arabis 
  ciliata 
  gla- 
  

   brata, 
  Arabis 
  hirsuta 
  glaberrima, 
  Veronica 
  

   spicata 
  nit 
  ens, 
  Amygdalus 
  persica 
  laevis, 
  

   Paeonia 
  corallina 
  leiocarpa, 
  &c. 
  

  

  On 
  the 
  contrary 
  we 
  find 
  elementary 
  species 
  in 
  

   different 
  genera 
  based 
  on 
  the 
  greatest 
  possible 
  

   diversity 
  of 
  features. 
  The 
  forms 
  of 
  Taraxacum 
  

   or 
  Helianthemum 
  do 
  not 
  repeat 
  those 
  of 
  Draba 
  

   or 
  Viola. 
  In 
  roses 
  and 
  brambles 
  the 
  distinguish- 
  

   ing 
  features 
  are 
  characteristic 
  of 
  the 
  type, 
  as
