Cochlearia  anglica  L.  Banks  of  River  Looe,  E.  Corn¬ 
wall,  v.c.  2,  May,  1910.  New  to  Mr.  Davey’s  district 
No.  8. — H.  Boyden. 
Sisymbrium  Columnce  Jacq.  Right  bank  of  River  Exe, 
nr.  Exeter,  S.  Devon,  v.c.  8,  Sept.,  1910.  This ‘plant  I 
found  last  September  in  fair  quantity  and  seemingly 
established,  growing  on  the  right  bank  of  the  Exe,  near 
the  water,  entangled  amongst  other  plants.  I  sent  a 
specimen  to  Mr.  Hiern,  of  Barnstaple,  who  named  it  as 
above,  and  this  opinion  was  confirmed  by  the  botanists  at 
the  British  Museum  to  whom  he  sent  a  specimen  gathered 
by  himself  in  the  place  I  had  indicated. — H.  Boyden. 
S.  Columnce  Jacq.,  FI.  Austr.  iv.  12,  t.  323.  Jacquin  shows 
S.  Irio  L.  and  S.  Columnce,  in  two  consecutive  folio  plates 
which  indicate  clearly  the  close  similarity  between  the 
two  species  in  habit  and  upper  leaf-characters.  From  his 
written  descriptions  of  the  living  plants  it  is  probable 
that  the  author  relied  upon  the  size  of  the  flowers  and  the 
direction  of  the  sepals  to  distinguish  them.  He  represents 
S.  Columnce  with  flowers  ^-inch  long  and  erect  sepals, 
while  the  other  has  flowers  J-inch  long  and  its  sepals 
patent. — S.  T.  Dunn. 
Brassica  Erucastrum  Vill.,  Newmarket  Heath,  Cambs., 
v.c.  29,  Aug.  27,  1910. — A.  J.  Crosfield.  There  is  a  specimen 
(sub  nom.  Erucastrum  inodorum  Reich.,  var.  Pollichii 
Schimp.  &  Spenn.)  in  the  Cambridge  University  Her¬ 
barium  from  the  same  locality,  collected -in  Aug.,  1885. 
Mr.  Druce  showed  me  the  plant  last  year  growing  on 
rubbish  heaps  by  the  side  of  the  “  heath.”  The  plant,  of 
course,  is  not  indigenous, — C.E.M.  Yes.  Evidently  an 
alien  which  our  climate  suits,  as  it  appears  to  be  spreading 
in  England.  Specimens  collected  by  Mr.  I.  H.  Burkiil 
from  the  same  locality  were  distributed  through  the  Club 
in  1897,  and  it  is  interesting  to  know  that  it  still  exists 
there.— C.E.S. 
Diplotaxis  muralis  DC.  [var.  Babingtonii  Syme] . 
Cultivated  ground,  Rock,  E.  Cornwall,  v.c.  2,  Aug.,  1910. — 
H.  E.  Fox.  Not  the  variety. — E.F.L.  Not  Babingtonii  of 
Syme,  which  is  a  much  larger  plant  with  leafy  stems. — 
A.B.  The  plant  sent  to  me  is  an  annual,  and  therefore  is 
not  D.  muralis ,  var.  Babingtonii  Syme ;  which,  indeed, 
does  not  deserve  to  be  distinguished,  being  merely  a
