S.  viminalis  L.,  forma.  Abbotsleigh,  near  Bristol,  N. 
Somerset,  v.c.  6,  April  and  Aug.  1890. — J.  W.  White. 
Flowering  branches  seem  rather  slender  and  glabrous  for 
pure  S.  viminalis  ;  but,  if  the  flowers  and  foliage  come 
from  the  same  stock,  I  can  call  them  nothing  else — E.F.L. 
S.  cinerea  L.,  form  or  hybrid  ?  Roadside  hedge, 
near  Yate,  W.  Glos.,  v.c.  84,  April  4  &  Aug.  14,  1918. — 
J.  W.  White.  (1)  cf  A-,  S.  caprea  L. ;  (2)  $  fruit,  appar¬ 
ently  S.  aurita  x  cinerea ;  ("8)  broad-leaved  S.  cinerea , 
which  may  be  put  to  /.  aquatica  Sm.  A  fine  example  of 
mixture  ! — E.F.L. 
S.  cinerea^  L.,  [/.  aquatica  (Sm.)J .  By  Roman  road, 
Hallen,  W.  Glos.,  v.c.  84,  April  13  &  Aug.  10,  1914. — Ida 
M.  Roper.  Approaching  /.  aquatica  (Sm.),  but  wanting 
the  full  breadth  of  leaf -blade  and  of  bracts  of  that  form.

S.  [nigricans  Sm.] .  Myddleton,  near  Warrington,  S. 
Lancs.,  v.c.  59,  June  1885. — J.  Comber.  S.  cinerea  L. —

Populus  alba  x  tremula  $  (=  P.  canescens  Sm.). 
Clack  Mill,  Westbury-on-Trym,  W.  Glos.,  v.c.  34,  Feb.  27 
&  July  24,  1914.; — Ida  M.  Roper.  This  is  certainly  P. 
canescens  Sm.,  but  there  is  no  evidence  of  its  being  a 
hybrid  between  P.  alba  and  P.  tremula ,  and  it  occurs 
frequently  in  localities  where  the  other  species  are  not 
found.  The  leaves  on  the  long  shoots  are  tomentose 
beneath  like  these,  the  lower  leaves  being  glabrous 
beneath. — A.B.J. 
P.  deltoidea  x  nigra  $  ( x  P.  canadensis  Monch). 
Planted:  “  Avenue  Lodge,”  Hitchin,  Herts.,  v.c.  20,  June 
10,  1918.  This  was  distributed  to  the  W.E.C.,  1913-14, 
but  Dr.  Moss  has  now  (18  Jan.  1914)  added  the  identifi¬ 
cation  with  x  P.  canadensis  Monch. — J.  E.  Little. 
Geratophy llum  submersum  L.  Pond,  Castlemorton, 
Worcs.,  v.c.  37,  Sept.  22,  1914.— A.  J.  Crosfield.  Yes; 
fruit  very  typical.  Near  tidal  waters,  where  alone  I  have 
seen  it,  the  habit  is  stouter  and  denser  than  in  these 
specimens.— E.S.M.  Yes. — A.B.  [Later];  By  the  name 
Dr.  Moss  gives  this,  I  suppose  he  places  it  under  C. 
demersum ;  continental  authors,  on  the  other  hand,  place
