  The 
  tubercles 
  of 
  this 
  specimen 
  are 
  more 
  numerous 
  as 
  the 
  termi-. 
  

   nation 
  is 
  approached, 
  favouring 
  the 
  idea 
  of 
  rootlets 
  issuing 
  from 
  those 
  

   points, 
  though 
  I 
  cannot 
  say 
  whether 
  these 
  tubercles 
  had 
  their 
  seat 
  

   only 
  in 
  the 
  epidermis 
  or 
  were 
  continuous 
  with 
  the 
  ligneous 
  cylinder 
  

   and 
  medulla. 
  

  

  Eichwald's 
  specimen 
  was 
  from 
  the 
  Cupriferous 
  Sandstone 
  near 
  

   Bielebee, 
  doubtless 
  the 
  same 
  horizon 
  as 
  that 
  of 
  Kargalinsk.

  some 
  twigs 
  from 
  the 
  Kar- 
  

   galinsk 
  mines, 
  which 
  he 
  attributed 
  to 
  Voltzia 
  brevifolia, 
  Brongn. 
  

   Brongniart, 
  however, 
  in 
  a 
  letter 
  to 
  De 
  Verneuil 
  (Geol. 
  Eussia, 
  vol. 
  ii. 
  

   pp. 
  503, 
  504), 
  was 
  of 
  opinion 
  that 
  Kutorga's 
  figure 
  rather 
  resem- 
  

   bled 
  twigs 
  of 
  Walchia, 
  and 
  that 
  at 
  any 
  rate 
  the 
  specimens 
  were 
  

   too 
  imperfect 
  to 
  be 
  placed 
  with 
  certainty 
  in 
  the 
  genus 
  Voltzia. 
  

  

  Eichwald, 
  in 
  his 
  Leth. 
  Eossica 
  (p. 
  229, 
  pi. 
  xix. 
  figs. 
  2 
  & 
  3, 
  1855 
  

   -1861), 
  also 
  repudiated 
  Kutorga's 
  determination, 
  and 
  described 
  the 
  

   twigs 
  as 
  Ullmannia 
  biarmica 
  and 
  U. 
  Bronnii. 
  The 
  specimen 
  I 
  

   here 
  submit 
  is 
  identical 
  with 
  his 
  U. 
  biarmica 
  ; 
  even 
  the 
  appendages 
  

   which 
  he 
  calls 
  bracts 
  or 
  flowers 
  are 
  present. 
  ' 
  He 
  states 
  the 
  locality 
  

   as 
  near 
  Kargala, 
  in 
  the 
  Bielebee 
  district, 
  while 
  Kutorga 
  gives 
  it 
  

   as 
  the 
  Kargala 
  mine, 
  in 
  the 
  Orenburg 
  district, 
  — 
  a 
  further 
  instance 
  

   of 
  the 
  confusion 
  constantly 
  occurring 
  between 
  these 
  two 
  places.

   (and 
  in 
  his 
  ' 
  Dyas,' 
  vol. 
  i.

  includes 
  Kutorga's 
  Voltzia 
  bre- 
  

   vifolia 
  among 
  the 
  synonyms 
  of 
  Ullmannia 
  sdarjinoides,

  The 
  next 
  mention 
  I 
  find 
  of 
  the 
  Orenburg 
  species 
  is 
  in 
  a 
  paper 
  

   by 
  Dr. 
  Ch. 
  Ernst 
  AYeiss, 
  of 
  Saarbriicken, 
  entitled 
  " 
  Ueber 
  Voltzia 
  

   und 
  andere 
  Pflanzen 
  des 
  bunten 
  Sandsteins 
  zwischen 
  der 
  untern 
  

   Saar 
  u. 
  dcm 
  Eheine," 
  where 
  he 
  cites 
  its 
  locality, 
  among 
  others, 
  as 
  

   needing 
  verification, 
  and 
  recommends 
  examination 
  by 
  those 
  who 
  

   have 
  facilities 
  for 
  doing 
  so. 
  

  

  Gbppert, 
  in 
  1864-65 
  ('PalaBontographica,' 
  " 
  Die 
  fossile 
  Flora 
  der 
  

   permischen 
  Formation") 
  remarks 
  that 
  Kutorga's 
  figures 
  1-3 
  could 
  

   refi 
  r 
  just 
  as 
  well 
  to 
  a 
  species 
  of 
  Walchia 
  ; 
  only 
  fig. 
  4 
  reminds 
  one 
  of 
  

   Voltzia. 
  As 
  for 
  Ullmannia 
  biarmica, 
  Goppert 
  considers 
  it 
  more 
  re- 
  

   lated 
  to 
  Walchia 
  than 
  Ullmannia, 
  and 
  is 
  strengthened 
  in 
  his 
  opinion 
  

   by 
  an 
  original 
  example 
  received 
  from 
  Wangenheirn 
  von 
  Qualen. 
  

  

  The 
  latest 
  opinion, 
  and 
  the 
  one 
  I 
  adopt, 
  is 
  by 
  Schimper 
  (op. 
  cit. 
  

   p. 
  239), 
  who 
  treats 
  Eichwald's 
  VUmannia 
  biarmica 
  as 
  a 
  Walchia, 
  

   viz. 
  IT", 
  biarmica. 
  At 
  the 
  same 
  time 
  I 
  may 
  mention 
  that 
  I 
  have 
  

   seen 
  in 
  the 
  collection 
  of 
  the 
  Mining 
  Institute, 
  St. 
  Petersburg, 
  an 
  

   undoubted 
  Ullmannia 
  from 
  the 
  Orenburg 
  or 
  Bielebee 
  Permian. 
  

  

  The 
  presence 
  of 
  a 
  midrib 
  in 
  the 
  leaves 
  may 
  be 
  inferred 
  from 
  the 
  

   specimen 
  now 
  exhibited 
  ; 
  and 
  some 
  faint 
  markings 
  indicate 
  parallel 
  

   venation. 
  This 
  mainly 
  influences 
  me 
  in 
  rejecting 
  the 
  Voltzia 
  deter- 
  

   mination.
