  THE

  OE 
  [Aug.

  897, 
  

  

  Vereeniging 
  are, 
  however, 
  almost 
  certainly 
  portions 
  of 
  long 
  and 
  

   narrow 
  leaves. 
  In 
  specimens 
  from 
  the 
  leaf-lteds 
  of 
  "both 
  Australia 
  

   and 
  India 
  it 
  is 
  possible 
  to 
  trace 
  a 
  gradual 
  alteration 
  in 
  leaf 
  form 
  

   from 
  the 
  narrow 
  linear 
  type 
  to 
  the 
  much 
  broader 
  spatulate 
  or 
  

   elongate-oval 
  form 
  ; 
  this 
  is 
  well 
  seen 
  in 
  specimens 
  in 
  the 
  Bunbnry 
  

   Collection, 
  which 
  includes 
  Australian 
  (Newcastle 
  Beds) 
  and 
  Indian 
  

   examples 
  of 
  Glossopteris-leaves. 
  It 
  is 
  in 
  any 
  case 
  convenient 
  to 
  

   designate 
  the 
  long 
  narrow 
  fronds 
  by 
  some 
  distinctive 
  term, 
  

   but 
  we 
  have 
  not, 
  I 
  believe, 
  sufficient 
  evidence 
  to 
  justify 
  the 
  

   use 
  of 
  a 
  distinct 
  specific 
  name 
  ; 
  for 
  this 
  reason 
  I 
  propose 
  to 
  speak 
  

   of 
  such 
  fronds 
  as 
  G. 
  Browniana 
  var. 
  angustifolia. 
  

  

  Several 
  specimens 
  of 
  Vertebraria 
  (Glossopteris-rh\zome) 
  have 
  

   been 
  found 
  at 
  Casey's 
  Township 
  (Francis), 
  but 
  the 
  pieces 
  sent 
  by 
  

   Mr. 
  Draper 
  are 
  not 
  so 
  well 
  preserved 
  as 
  those 
  figured 
  by 
  Zeiller 
  

   from 
  the 
  same 
  beds. 
  The 
  largest 
  example 
  in 
  the 
  Draper 
  collection 
  

   is 
  one 
  from 
  Vereeniging, 
  which 
  has 
  a 
  length 
  of 
  10 
  cm., 
  and 
  

   shows 
  the 
  characteristic 
  transverse 
  markings 
  which 
  have 
  recently 
  

   been 
  cleverly 
  interpreted 
  by 
  Zeiller.

  The 
  generic 
  name 
  Noeggeraihiopsis 
  was 
  proposed 
  by 
  Feistmantel 
  

   in 
  1879 
  1 
  for 
  certain 
  leaves 
  previously 
  referred 
  by 
  Bunbury 
  to 
  

   Noeggerathia. 
  The 
  precise 
  nature 
  of 
  this 
  plant 
  is 
  still 
  undecided, 
  

   and 
  the 
  fragments 
  obtained 
  in 
  the 
  Transvaal 
  do 
  not 
  add 
  anything 
  

   of 
  botanical 
  importance 
  to 
  our 
  previous 
  knowledge.

  This 
  basal 
  leaf-fragment, 
  5 
  cm. 
  in 
  length, 
  agrees 
  

   exactly 
  with 
  the 
  specimens 
  described 
  by 
  Zeiller 
  from 
  the 
  same 
  

   locality. 
  In 
  another 
  specimen 
  from 
  Casey's 
  Township 
  (Francis) 
  

   there 
  are 
  two 
  tapered 
  portions 
  of 
  leaves 
  lying 
  parallel 
  to 
  one 
  

   another, 
  and 
  in 
  such 
  a 
  position 
  as 
  to 
  suggest 
  the 
  attachment 
  of 
  

   two 
  pinnae 
  to 
  a 
  rachis 
  ; 
  but 
  the 
  bases 
  are 
  not 
  seen, 
  and 
  it 
  is 
  equallv 
  

   possible 
  that 
  their 
  position 
  may 
  be 
  entirely 
  accidental. 
  Imperfect 
  

   impressions 
  of 
  what 
  are 
  most 
  probably 
  Noeggerathiopsis-le&ves 
  occur 
  

   in 
  association 
  with 
  the 
  Sigillaria 
  at 
  Vereeniging.

  In 
  this 
  specimen 
  there 
  is 
  a 
  portion 
  of 
  a 
  leaf 
  

   seen 
  at 
  a, 
  with 
  a 
  strongly 
  convex 
  surface 
  and 
  narrow 
  base 
  ; 
  the 
  

   upper 
  portion 
  is 
  torn 
  across 
  irregularly 
  at 
  x. 
  The 
  surface-features 
  

   are 
  not 
  very 
  distinct, 
  but 
  the 
  leaf 
  is 
  traversed 
  by 
  parallel 
  or 
  slightly 
  

   spreading 
  veins 
  which 
  appear 
  to 
  fork 
  occasionally 
  and 
  possibly 
  

   anastomose, 
  although 
  it 
  is 
  very 
  difficult 
  to 
  follow 
  accurately 
  their 
  

   course 
  owing 
  to 
  imperfect 
  preservation.
