This  is,  anyhow,  neither  rurivagum  (Jord.),  arenastrum 
(Bor.),  nor  microspermum  (Jord.). — E.S.M.  I  have  this 
form  in  my  herbarium  under  var.  agrestinum  (Jord.),  as  a 
narrow-leaved  form ;  it  is  quite  common,  yet  not,  I  think, 
the  agrestinum  usually  so  described. — E.F.L.  Seems  to 
come  best  under  the  var.  arenastrum  (Bor.). — C.E.S.

Aug.  6,  1906.— A.  R.  Horwood.  This  is  the  tree  which  I 
name  U.  suberosa ,  Ehrh.  It  is  characterised  by  an  incon¬ 
spicuous  bole,  long  spreading  branches,  leaves  larger  and 
more  acutely  pointed  than  in  typical  XJ.  campestris ,  nearly 
smooth  on  the  upper  surface;  the  bark  of  the  young 
shoots  (of  2 — 3  years  old)  and  the  numerous  suckers  very 
suberous.  It  is  common  in  upland  situations  and  in 
mountain  valleys  when  U.  campestris  is  not  found,  and  it 
has  all  the  appearance  of  a  native  tree.— A.  Ley.

1905,  p.  184.— A.  Ley.  I  believe  that  this  is  U.  dioica,  L.,

the  lower  leaves,  and  we  get  it  much  more  extreme. _ 
S.H.B.  Quite  so. — E.F.L.  I  believe  that  this  is  correct.

Betula  intermedia,  Thomas,  (B.  nana  x  pubescens). 
Glen  Callater  (about  1,700  feet),  S.  Aberdeensh.,  v.c.  92, 
July  23,  1906.  A  small  tree,  about  12  feet  high.  Decidedly 
nearer  to  B. pubescens,  as  usual;  but  I  have  hardly  any 
doubt  about  its  being  a  hybrid  with  B.  nana.  The  original 
British  intermedia  was  found  not  far  off,  but  higher  un. _
