  two 
  contiguoiis 
  countries 
  exhibit 
  such 
  wide 
  differences 
  between 
  their 
  respec- 
  

   tive 
  floras. 
  Many 
  of 
  the 
  characteristic 
  genera 
  of 
  Australia 
  are 
  represented 
  

   in 
  New 
  Zealand 
  by 
  one, 
  or 
  perhaps 
  two, 
  species 
  common 
  to 
  botli 
  countries, 
  

   but 
  not 
  found 
  elsewhere 
  ; 
  but 
  exactly 
  the 
  same 
  phenomenon 
  is 
  exhibited 
  in 
  

   Australia 
  by 
  characteristic 
  New 
  Zealand 
  genera. 
  Amongst 
  the 
  former 
  may 
  

   be 
  named 
  Pomaclerris 
  elliptica, 
  Leucopogon 
  richei, 
  Leptospernmm 
  scoparium, 
  

   Poranthcra 
  microphglla 
  ; 
  amongst 
  the 
  latter 
  Coprosma 
  piimila, 
  Celmisia 
  longi- 
  

   folia, 
  Senecio 
  lautus, 
  Pimelea 
  longifolia. 
  It 
  is 
  evident, 
  therefore, 
  that 
  a 
  

   portion 
  of 
  the 
  Australian 
  flora 
  has 
  been 
  derived 
  directly 
  from 
  this 
  country. 
  

  

  It 
  will 
  be 
  advisable 
  to 
  indicate 
  the 
  chief 
  points 
  of 
  interest 
  connected 
  

   with 
  the 
  species 
  and 
  genera 
  common 
  to 
  both 
  countries 
  without 
  going 
  into 
  

   detail 
  to 
  any 
  great 
  extent. 
  

  

  Eanunculace®. 
  — 
  Clematis 
  is 
  common 
  to 
  both 
  countries, 
  but 
  the 
  species 
  of 
  

   each 
  are 
  endemic. 
  In 
  Myosunts, 
  a 
  genus 
  of 
  two 
  species, 
  it 
  is 
  worthy 
  of 
  note 
  

   that 
  the 
  European 
  form 
  is 
  found 
  in 
  Australia 
  ; 
  the 
  American 
  form 
  in 
  New 
  

   Zealand. 
  Rainiiiculus 
  is 
  represented 
  by 
  twenty-six 
  species 
  in 
  New 
  Zealand 
  

   and 
  eleven 
  in 
  Australia, 
  of 
  which 
  five 
  are 
  common 
  to 
  both 
  countries. 
  Three 
  

   of 
  these 
  are 
  not 
  found 
  elsewhere. 
  Caltha 
  is 
  rej^resented 
  by 
  a 
  single 
  endemic 
  

   species 
  in 
  each 
  country. 
  The 
  larger 
  order 
  Crnciferse 
  which 
  is 
  sparingly 
  

   represented 
  in 
  this 
  colony, 
  contains 
  three 
  species 
  common 
  to 
  both 
  countries, 
  

   but 
  of 
  wide 
  distribution, 
  and 
  a 
  fourth 
  not 
  found 
  elsewhere. 
  One 
  of 
  our 
  

   violets 
  extends 
  to 
  Tasmania, 
  and 
  Hymenanthera 
  is 
  represented 
  by 
  a 
  single 
  

   species 
  in 
  each 
  country. 
  Pittosporese, 
  an 
  order 
  of 
  which 
  all 
  the 
  genera, 
  

   except 
  Pittosporiim, 
  are 
  restricted 
  to 
  Australia, 
  is 
  represented 
  in 
  New 
  Zea- 
  

   land 
  by 
  sixteen 
  species 
  of 
  Pittosporum, 
  all 
  of 
  which 
  are 
  endemic. 
  Caryophyllese 
  

   comprises 
  three 
  genera 
  and 
  four 
  species 
  common 
  to 
  both 
  countries. 
  In 
  

   Malvaceae, 
  Plagianthus 
  is 
  restricted 
  to 
  these 
  countries, 
  but 
  has 
  no 
  species 
  

   common 
  to 
  both. 
  Both 
  countries 
  possess 
  two 
  species 
  of 
  Hibiscus 
  of 
  wide 
  

   distribution. 
  

  

  In 
  Lineae, 
  Linum 
  marginals 
  is 
  the 
  only 
  common 
  species, 
  and 
  does 
  not 
  

   occur 
  elsewhere. 
  Geraniaceoi 
  has 
  three 
  species 
  of 
  Geranium, 
  one 
  of 
  Pelar- 
  

   gonium 
  and 
  two 
  of 
  Oxalis, 
  common 
  to 
  both 
  countries. 
  In 
  Eutaceas 
  all 
  our 
  

   species 
  are 
  endemic, 
  but 
  belong 
  to 
  Australian 
  genera. 
  ^Meliace^e 
  is 
  repre- 
  

   sented 
  m 
  both 
  countries 
  by 
  a 
  single 
  endemic 
  species 
  of 
  Dysoxyhun, 
  and 
  

   Olacinete 
  by 
  one 
  of 
  Peimantia. 
  

  

  In 
  Ehamnese, 
  Pomaclerris, 
  a 
  genus 
  restricted 
  to 
  Australia 
  and 
  New 
  

   Zealand, 
  and 
  specially 
  abundant 
  in 
  cool 
  regions 
  of 
  the 
  former, 
  is 
  represented 
  

   here 
  by 
  five 
  species, 
  three 
  of 
  which 
  are 
  common 
  to 
  both 
  countries. 
  Discaria 
  

   has 
  a 
  single 
  species 
  in 
  each 
  country. 
  Of 
  Sapindaceas 
  only 
  a 
  single 
  species 
  

   of 
  Dodoncsa 
  is 
  common 
  to 
  both 
  countries. 
  The 
  genus 
  is 
  more 
  largely 
  

   developed 
  in 
  Australia 
  than 
  elsewhere, 
  but 
  the 
  New 
  Zealand 
  species 
  is 
  the 
  

   most 
  widely 
  distributed 
  of 
  all.
