  Looking 
  at 
  the 
  points 
  of 
  contact 
  between 
  the 
  two 
  floras 
  afforded 
  by 
  

   Leguminos£e 
  alone, 
  the 
  relationship 
  appears 
  but 
  slender. 
  This 
  order, 
  

   which 
  stands 
  second 
  only 
  to 
  Composit^e 
  amongst 
  flowering 
  plants 
  in 
  the 
  

   number 
  of 
  species 
  it 
  contains, 
  includes 
  more 
  than 
  one-eighth 
  of 
  the 
  

   Phanerogamia 
  of 
  Australia, 
  where 
  it 
  comprises 
  nearly 
  as 
  many 
  species 
  as 
  

   are 
  found 
  in 
  the 
  entire 
  Phanerogamic 
  flora 
  of 
  New 
  Zealand 
  ; 
  yet, 
  amongst 
  

   the 
  thousand 
  Australian 
  forms 
  not 
  one 
  is 
  common 
  to 
  both 
  countries, 
  a 
  fact 
  

   which 
  is 
  the 
  more 
  remarkable 
  as 
  the 
  seeds 
  of 
  most 
  plants 
  of 
  this 
  order 
  

   suffer 
  less 
  than 
  others 
  when 
  drifted 
  by 
  marine 
  currents. 
  The 
  seeds 
  of 
  

   Eiitada 
  scandens 
  are 
  drifted 
  from 
  the 
  shores 
  of 
  Northern 
  Australia 
  to 
  the 
  

   coast 
  of 
  New 
  Zealand, 
  and 
  have 
  been 
  picked 
  up 
  even 
  on 
  the 
  East 
  Coast 
  as 
  

   far 
  south 
  as 
  Tauranga. 
  It 
  is 
  certainly 
  matter 
  for 
  remark 
  that 
  no 
  sea-borne 
  

   seeds 
  of 
  Acacia 
  or 
  other 
  large 
  Australian 
  genera 
  appear 
  to 
  have 
  germinated 
  

   on 
  the 
  New 
  Zealand 
  coasts. 
  

  

  Three 
  genera 
  of 
  this 
  order, 
  however, 
  are 
  common 
  to 
  both 
  countries, 
  and 
  

   the 
  first 
  two 
  are 
  not 
  found 
  elsewhere. 
  Clianthus, 
  of 
  which 
  a 
  single 
  species 
  

   is 
  endemic 
  in 
  the 
  extreme 
  northern 
  portion 
  of 
  New 
  Zealand, 
  and 
  another 
  in 
  

   Australia, 
  the 
  first 
  being 
  a 
  glabrous 
  undershrub, 
  the 
  second 
  a 
  pilose 
  herb. 
  

   Sicainsonia, 
  which 
  is 
  represented 
  here 
  by 
  a 
  single 
  species 
  confined 
  to 
  the 
  

   Southern 
  Alps, 
  and 
  by 
  numerous 
  species 
  in 
  Australia. 
  Sophora 
  has 
  two 
  

   species 
  in 
  Australia 
  and 
  another 
  in 
  this 
  colony, 
  but 
  belonging 
  to 
  a 
  different 
  

   section 
  of 
  the 
  genus. 
  Carmichcelia 
  and 
  Notospartiinn, 
  the 
  only 
  additional 
  

   genera 
  in 
  New 
  Zealand, 
  are 
  endemic, 
  and 
  have 
  no 
  near 
  allies 
  in 
  Australia. 
  

  

  Both 
  countries 
  are 
  characterized 
  by 
  a 
  great 
  paucity 
  of 
  Eosacese. 
  In 
  

   New 
  Zealand 
  we 
  find 
  four 
  genera 
  and 
  thirteen 
  species 
  ; 
  in 
  Australia, 
  seven 
  

   genera 
  and 
  seventeen 
  species 
  ; 
  four 
  genera 
  and 
  four 
  species 
  being 
  common 
  

   to 
  both. 
  

  

  In 
  Saxifragese, 
  the 
  relationship 
  is 
  generic 
  only, 
  Quintinia 
  and 
  Aclcama 
  

   not 
  being 
  found 
  elsewhere, 
  and 
  Weiinnannia 
  having 
  a 
  wider 
  distribution. 
  

  

  Drosera 
  is 
  largely 
  developed 
  in 
  Austraha, 
  where 
  it 
  comprises 
  forty-one 
  

   species, 
  five 
  of 
  which 
  extend 
  to 
  New 
  Zealand, 
  but 
  with 
  the 
  possible 
  excep- 
  

   tion 
  of 
  D. 
  spathulata, 
  are 
  not 
  found 
  in 
  other 
  countries. 
  In 
  Halorage®, 
  four 
  

   genera 
  and 
  eight 
  species 
  are 
  common 
  to 
  both 
  countries. 
  

  

  Myrtaceffi 
  ranks 
  next 
  to 
  Leguminosa, 
  in 
  the 
  extent 
  to 
  which 
  it 
  imparts 
  

   a 
  peculiar 
  character 
  to 
  the 
  Australian 
  flora, 
  but 
  has 
  only 
  a 
  single 
  species 
  

   common 
  to 
  both 
  countries. 
  Metrosideros, 
  Myrtus, 
  and 
  Eugenia 
  are 
  repre- 
  

   sented 
  by 
  different 
  species 
  in 
  each 
  country. 
  

  

  Epilobium, 
  a 
  genus 
  developed 
  in 
  New 
  Zealand 
  to 
  a 
  remarkable 
  extent, 
  

   has 
  six 
  species 
  common 
  to 
  both 
  countries, 
  four 
  of 
  which 
  are 
  not 
  known 
  to 
  

   occur 
  elsewhere. 
  

  

  Of 
  umbeUiferous 
  plants, 
  eight 
  genera 
  and 
  six 
  species 
  are 
  common 
  to 
  

   both 
  countries. 
  The 
  trimorphic 
  arahads 
  of 
  New 
  Zealand 
  have 
  nothing 
  to 
  

   epresent 
  them 
  in 
  Australia.
