Polygonum  heterophyllum  Lindmann  (P.  aviculare 
L.,  pro  parte).  Ref.  No.  3918.  Sandy  wheat-stubble,  West 
Monkton,  S.  Somerset,  v.c.  5,  Sept.  23,  1913.  Prostrate, 
slender. — Edward  S.  Marshall. 
Urtica  dioicci  L.,  var.  Herefordshire  Beacon,  v.c.  36, 
Aug.  23,  1913. — A.  J.  Crosfield.  Top  pieces  only  of  this 
species  are  not  enough  to  form  an  opinion  on.  It  seems 
the  ordinary  form. — E.F.L. 
Betala  alba  L.  x  pubescens  Ehrh.,  vaL*.  microphylla. 
Ref.  No.  3892.  Ailt  Coire  Pheiginn,  west  of  Garth 
Castle,  near  Fortingal,  Mid  Perthsh.,  v.c.  88,  Sept.  2, 
1913.  Dr.  C.  E.  Moss  and  1  agreed  in  so  naming  this. 
It  was  a  tree  with  pendulous  branches,  20  to  25  feet  high, 
and  did  not  produce  female  catkins  at  all  freely.  Nearer 
to  the  pubescens  parent  in  foliage  ;  but  there  is  good 
evidence  of  B.  alba. — Edward  S.  Marshall. 
B.  alba  Ait.  x  pubescens  (fide  C.  E.  Moss).  Planted 
in  the  garden  of  “  The  Grange,”  Hitch  in,  Herts.,  v.c.  20, 
April  30,  1913.  A  very  fine  tree. — J.  E.  Little. 
Quercus  Bobur  L.,  var.  intermedia  (D.  Don).  Malvern 
Wells,  Worcs.,  v.c.  37,  Aug.  26,  1913. — A.  J.  Crosfield. 
This  is  a  narrow-leaved  form  of  Q.  sessiliflora  Salisb. 
Don’s  var.  intermedia  cannot  be  separated  from  sessiliflora , 
as  is  very  clearly  shown  by  Dr.  Moss  (Jl.  Bot.  1910,  p.  5). 
— A.B.J.  Perhaps  Q.  Bobur  x  sessiliflora ;  but,  if  so, 
nearer  Q.  sessiliflora.  Every  stage  between  the  putative 
parents  occurs ;  and  there  must  often  be  some  doubt 
therefore  in  determining  dried  specimens. — C.E.M. 
Q.  Bobur  L.,  var.  sessiliflora  (Salisb.).  Malvern 
Wells,  Worcs.,  v.c.  37,  Aug.  26,  1913. — A.  J.  Crosfield. 
Q.  sessiliflora  Salisb.— E.S.M.  Correct,  but  is  best  cited 
as  Q.  sessiliflora  Salisb.,  as  most  botanists  and  foresters 
now  regard  it  as  distinct  from  Q.  Bobur  L.  (Q.  peduncu- 
lata  Willd.). — A.B.J.  Q.  sessiliflora  var.  genuina.  See 
“  Camb.  Brit.  FI.”  II.,  74  (1914).— C.E.M. 
Salix  triandra  L.,  var.  Hoffmaniana  (Sm.).  Banks 
of  Ouse,  Lindfield,  E.  Sussex,  v.c.  14,  Sept.  9,  1913. — 
R.  S.  Standen.  Leaf-material  only  ;  looks  right _ E.S.M. 
Nearest  to  var.  Hoffmaniana ,  but  one  of  the  frequent
