Alnus  rotundi folia  Mill.,  var.  incisa,  from  the  banks 
of  the  Cherwell,  in  and  near  the  Parks,  Oxford,  v.c.  28, 
June  11,  1909.  The  same  form  I  suppose  as  A.  glutinosa 
Gaertn.,  var.  incisa  Syme. —  E.  F.  Linton.  (See  also  Rept. 
B.E.C.,  1909,  p.  473). 
Quercus  Robur  L.,  var.  sessiliflora  (Salisb.).  Llanbe- 
drog  Head,  Carnarvonsh.,  v.c.  49,  Aug.  18,  1909. — A.  M. 
Geldart.  Yes,  Q.  sessiliflora  Salisb.  If  Salisbury’s  plant 
be  reduced  to  a  variety,  it  must  be  quoted  as  Q.  Robur , 
var.  sessilis  Martyn;  but  most  botanists  regard  it  as  a 
species. — C.E.M. 
Q.  Robur  ( =  pedunculata)  X  sessiliflora.  White 
Wood,  Gamlingay,  Cambs.,  v.c.  29,  May  20  and  Oct.  27, 
1909.  From  same  tree.  (See  Jl.  Bot.  1910,  p.  1). — C.  E. 
Moss. 
Q.  Robur  L.,  var.  intermedia  (D.  Don.).  Stoughton, 
Leics.,  v.c.  55,  Sept.  1,  1909. — A.  R.  Horwood.  No  ;  the 
specimen  is  Q.  Robur  x  sessiliflora ,  but  probably  not  the 
first  cross.  A  new  county  record. — C.E.M. 
Castanea  sativa  Mill.  Thorpe  Wood,  near  Norwich, 
E.  Norfolk,  v.c.  27,  July  17,  1909. — A.  M.  Geldart. 
Salix  hippophce folia  Thuill.  Low  bushes  on  the  right 
bank  of  the  Wye  near  Ross,  Herefordsh.,  v.c.  36,  May  8 
and  Aug.  6,  1909. — A.  Ley.  A  good  intermediate  form 
of  this  hybrid  ( S .  triandra  x  viminalis),  remarkable  for 
the  catkins — which  are  usually  male  above  and  below,  and 
female  through  the  middle  part  of  each  catkin. — E.F.L. 
S.  fragilis  L.,  female  plant.  Mitcheldean  Meend,  W. 
Glos.,  v.c.  34,  May  17  and  Sept.  8,  1909.  Bark  light  yellow; 
foliage  glaucous.  I  believe  this  to  be  type  fragilis ,  not 
b.  britannica :  having  the  leaf  more  suddenly  acuminate 
from  a  broader  centre,  and  having  twigs  far  more  brittle 
than  the  variety.  I  have  never  before  seen  the  female 
tree  of  fragilis  growing. — A.  Ley.  Typical  S.  fragilis  L. 
—E.F.L. 
S.  viridis  Fr.  River  bank,  Foy,  Herefordsh.,  v.c.  36, 
May  25  and  Sept.  6,  1909. — A.  Ley.  The  foliage  of  this 
willow  I  readily  assent  to  as  S.  viridis  Fr.  ( S .  alba  x 
fragilis ),  being  apparently  the  same  as  the  foliage  of  a
