  §11. 
  Cokallian 
  Rocks. 
  

  

  Plants. 
  — 
  4 
  genera 
  and 
  7 
  species 
  occur, 
  all 
  confined 
  to 
  these 
  rocks. 
  

   It 
  is 
  necessary 
  that 
  I 
  name 
  them, 
  as, 
  with 
  the 
  exception 
  of 
  2 
  species, 
  

   they 
  are 
  the 
  last 
  we 
  know 
  of 
  the 
  Jurassic 
  flora. 
  The 
  Conifcrae 
  

   and 
  the 
  Cycadeae 
  are 
  the 
  two 
  families 
  represented. 
  Araucarites 
  

   Hudlestoni 
  is 
  the 
  only 
  Conifer 
  ; 
  Bennettites 
  Peacliianus, 
  Bucl- 
  

   landia 
  Milleriana, 
  Yatesia 
  crassa, 
  and 
  Y. 
  Joassiana 
  represent 
  the 
  

   Cycadea). 
  Carpolitlies 
  Bucldandi 
  and 
  C.

  must 
  be
