  the 
  same 
  genus 
  have 
  also 
  been 
  recorded 
  to 
  pro- 
  

   duce 
  gamopetalous 
  flowers, 
  as 
  for 
  instance, 
  

   Papaver 
  hybridum, 
  by 
  Hoffmann. 
  Poppies 
  are 
  

   not 
  the 
  sole 
  example 
  of 
  accidental 
  gamopetaly. 
  

   Linnaeus 
  observed 
  the 
  same 
  deviation 
  long 
  ago 
  

   for 
  Saponaria 
  officinalis, 
  and 
  since, 
  it 
  has 
  been 
  

   seen 
  in 
  Clematis 
  Vitalba 
  by 
  Jaeger, 
  in 
  Peltaria 
  

   alliacea 
  by 
  Schimper, 
  in 
  Silene 
  annulate 
  by 
  Bo- 
  

   reau 
  and 
  in 
  other 
  instances. 
  No 
  doubt 
  it 
  is 
  not 
  

   at 
  all 
  of 
  rare 
  occurrence, 
  and 
  the 
  origin 
  of 
  the 
  

   present 
  gamopetalous 
  families 
  is 
  to 
  be 
  consid- 
  

   ered 
  as 
  nothing 
  extraordinary. 
  It 
  is, 
  as 
  a 
  mat- 
  

   ter 
  of 
  fact, 
  remarkable 
  that 
  it 
  has 
  not 
  taken 
  

   place 
  in 
  more 
  numerous 
  instances, 
  and 
  the 
  mal- 
  

   lows 
  show 
  that 
  such 
  opportunities 
  have 
  been 
  

   available 
  at 
  least 
  more 
  than 
  once. 
  

  

  Other 
  instances 
  of 
  taxonomic 
  anomalies 
  are 
  

   afforded 
  by 
  leaves. 
  Many 
  genera, 
  the 
  species 
  of 
  

   which 
  mainly 
  bear 
  pinnate 
  or 
  palmate 
  leaves, 
  

   have 
  stray 
  types 
  with 
  undivided 
  leaves. 
  

   Among 
  the 
  brambles, 
  Rubus 
  odoratus 
  and 
  

   R. 
  flexuosus 
  may 
  be 
  cited, 
  among 
  the 
  aralias, 
  

   Aralia 
  crassifolia 
  and 
  A. 
  papyrifera, 
  and 
  

   among 
  the 
  jasmines, 
  the 
  deliciously 
  scented 
  

   sambac 
  (Jasminum 
  Sambac). 
  But 
  the 
  most 
  

   curious 
  instance 
  is 
  that 
  of 
  the 
  telegraph-plant, 
  

   or 
  Desmodium 
  gyrans, 
  each 
  complete 
  leaf 
  of 
  

   which 
  consists 
  of 
  a 
  large 
  terminal 
  leaflet 
  and 
  

   two 
  little 
  lateral 
  ones. 
  These 
  latter 
  keep 
  up,
