Erophila  - .  Golf  Links,  Wallasey,  Cheshire,  v.c. 
58,  May  1907  and  1908.  Pods  terete  or  subterete. — E.  & 
H.  Drabble.  I  cannot  name  this  interesting  little  plant. 
Foreign  help  is  much  needed  for  the  determination  of 
several  curious  British  Erophilae. — E.S.M. 
E.  virescens  Jord.  Milford,  Surrey,  v.c.  17,  April  17, 
1899  and  April  17,  1909. — Coll.  E.  S.  Marshall.  Comm. 
R.  S.  Standen. 
E.  inflata  Hook.  fil.  Ironstone  walls,  Duston,  North  - 
amptonsh.,  v.c.  82,  May,  1909. — Coll.  F.  S.  Willcox.  Comm. 
W.  Bell.  Plants  from  this  wall  were  named  E.  inflata  by 
the  Rev.  E.  S.  Marshall. — W.  Bell.  The  capsules  look 
rather  more  turgid  than  in  ordinary  E.  verna  {vulgaris 
DC.) ;  but  this  character  is  easily  obscured  by  pressure  in 
drying,  and  I  cannot  feel  at  all  sure  that  the  present 
plants  are  true  E.  inflata  Hook.  fil. — E.S.M.  If  the  figure 
in  i  Eng.  Bot.”  is  to  be  depended  upon,  I  should  say  not 
inflata. — A.B. 
Sisymbrium  Columnce  Jacq.  (=  S.  orientate  L.). 
Birkenhead  Docks,  Cheshire,  v.c.  58,  Aug.,  1907. — E.  & 
H.  Drabble. 
S.  hispanicum  Jacq.  Waste  ground,  St.  Philip’s 
Marsh,  Bristol,  W.  Glos.,  v.c.  34,  June  30,  1909.  This 
alien  has  been  well  established  for  some  years  on  ground 
that  has  been  raised  by  tipping  city  refuse. — Ida  M.  Roper. 
The  Sisymbrium  will  not  do  for  S.  hispanicum,  which  has 
sessile  leaves  and  adpressed  pods.  It  seems  to  me  to 
come  nearer  to  S.  obtusangulum  Schl.,  of  which  the  leaves 
are  pinnately  lobed  and  obtuse  with  rounded  sinuses.  It 
is  a  native  of  Spain,  and  must,  I  suppose,  have  been 
brought  from  there  with  hay,  or  with  some  agricultural 
seed.  I  see  the  Index  Kewensis  refers  S.  obtusangulum 
Schl.  to  Brassica  Erucastrum  L.  It  is  almost  impossible 
to  name  Cruciferae  unless  the  seed  is  fully  formed. 
— E.  M.  Holmes.  I  believe  this  to  be  a  form  of  Brassica 
elongata  Ehrh. — S.  T.  Dunn. 
Subularia  aquatica  L.  Llyn  Idwal,  Carnarvonsh., 
v.c.  49,  Aug.  6,  1909.— G.  Goode. 
Brassica  Rapa  L.,  var.  Briggsii  Wats.  Station  yard, 
Portishead,  N.  Somerset,  v.c.  6,  July  1,  1909. — Ida  M. 
Roper.  Yes. — A.L.  Rightly  named,  I  believe. — E.S.M.
