Barbarea  arcuata  Reichb.  Origin,  side  of  drain-ditch, 
Upton-on- Severn,  Worcs.,  v.c.  37.  Cult.  Ledbury,  June  14 
and  Aug.  13,  1907. — S.  H.  Bickham.  Right,  I  believe. 
Seeds  longer  than  broad,  corolla  persistent. — A.  Ley. 
Beautiful  specimens  of  this  plant,  which  is  doubtless  the 
B.  arcuata  of  many  English  and  Continental  botanists, 
but  it  differs  from  the  B.  arcuata  of  Reicbenbacb  (“  leones 
FI.  Germ.”  ii.,  Fig.  4356)  in  a  character  on  which  Syme 
(“  E.B.”  ed.  iii.,  vol.  i.,  173)  lays  great  stress,  namely  Ll  the 
seed  being  broad  and  short.  In  Reichenbach’s  type,  which 
I  have  also  examined,  the  seed  is  long  and  narrow,  i.e., 
more  than  twice  as  long  as  broad.  This  Upton  plant  is 
what  in  “  Flora  of  Berkshire,”  p.  44,  I  have  called 
B.  vulgaris,  var.  decipiens  (—  B.  lyrata  Aschers.,  var. 
decipiens) ;  but  if  anything  the  flowers  are  a  trifle  larger, 
my  plant  being  near  to,  if  not  identical  with,  the  plant 
wrongly  figured  by  Reichenbach  in  Sturm’s  “  Deutschland 
Flora”  as  arcuata,  and  this  may  be  the  origin  of  the 
confusion  respecting  it  by  continental  authors. — G.  Claridge 
Druce.  The  seeds  of  this  plant,  though  they  vary  some¬ 
what,  approach  so  closely  to  the  character  of  those  in 
Reichenbach’s  Icon.  No.  4357  in  Iconogr.  Cent,  xi.,  Pt.  2, 
that  taking  other  marks  into  consideration  there  need  be 
no  doubt  at  all  that  Mr.  Bickham’s  specimens  are  good 
examples  of  the  true  B.  arcuata,  Reichb. — J.  R.  Drummond 
and  A.  B.  Jackson. 
B. - .  Origin,  from  an  old  coal  tip,  Glais,  Glarn- 
organsh.,  v.c.  41.  Cult.  May  22  and  July  21,  1908.  See, 
on  this  plant,  Rept.  B.E.C.  1907,  p.  273;  where  Mr.  Jack- 
son  makes  interesting  suggestions  concerning  it.  The 
short  silicles  containing  very  few  seeds  suggest  a  de¬ 
formity:  the  plant  however  grows,  self  sown,  from  seed. 
In  the  original  locality  it  was  scattered  over  a  small  area 
of  old  coal-pit  debris  which  had  become  thinly  covered 
with  grass,  and  had  the  aspect  of  an  introduction. — A.  Ley. 
The  adequate  material  now  received  from  Mr.  Ley  leaves 
no  question  that  this  is  Barbarea  taurica  DC.  Specimens 
in  the  Kew  Herb,  which  are  in  every  respect  identical, 
except  as  regards  the  development  of  the  seed,  with  the 
Glamorganshire  plant  have  been  identified  by  Anderson 
and  others  unhesitatingly  with  the  plant  of  the  “  Systema;” 
and  Mr.  Duthie,  who  has  also  seen  the  plant  growing  in 
Kashmir,  agrees  that  Mr.  Ley’s  specimens  resemble  the
