Salix  triandra  L.,  var.  Hoffmaniana  (Sm.).  On  the  Ouse, 
E.  Mascalls,  Lindfield,  E.  Sussex,  v.c.  14,  Catkins,  Apl.  80, 
1912.  Foliage,  Sept.  9,  1912 — R.  S.  Standen.  Right —

S.  [purpurea  L.,  var.]  2  .  Severn  flats,  near  Pilning, 
W.  Glos.,  v.c.  84,  March  26  and  July  2,  1912 — Ida  M.  Roper. 
There  is  some  mistake  here ;  certainly  not  S.  purpurea , 
but  what  it  really  is  I  cannot  say.  The  stem  of  the 
flowering  branch  is  very  shining,  as  in  S.  decipiens  Hoffm.: 
the  more  or  less  recurved,  slender  catkins  (rather  young) 
average  barely  an  inch  in  length.  The  mature  foliage  is 
most  like  S.  fragilis  L.,  but  considerably  resembles  S. 
decipiens ,  the  female  plant  of  which  is  unknown  in  Britain. 
Can  it  be  that  ?  I  have  not  seen  a  description  of  the 
inflorescence _ E.S.M.  S.  viridis  Fr.  (if  British)  ;  but  the 
very  small  catkins  suggest  the  weeping  willow  ?  Can 
grown-up  catkins  be  supplied  ?— E.F.L. 
S.  purpurea  L.  $  .  Withy-bed,  Walton-in-Gordano,  N. 
Somerset,  v.c.  6,  Mar.  27  and  Aug.  18,  1912 — Ida  M.  Roper. 
Yes _ E.F.L. 
S'  purpurea  L.,  var.  [Woolgariana  (Borr.)] .  Swamp  by 
R.  Wey,  north  of  Guildford,  Surrey,  v.c.  17,  April  and  Aug. 
1912— J.  Comber.  By  the  shape  of  the  leaves,  and  the 
colour  of  the  young  branches,  I  judge  this  to  be  var. 
Lambertiana  (Sm.) — E.F.L. 
S.  aurita  L.  [  x  cinerea  L.]  2  and  $ .  Meadow  near 
Knebworth  Great  Wood,  Herts.,  v.c.  20,  April  1  and  July 
4, 1912.— J.  E.  Little.  Pure  S.  aurita  L.;  typical  in  catkins, 
nor  can  I  see  any  trace  of  S.  cinerea  L.  in  the  leaves  and 
stipules.— E.S.M.  The  $  pieces  may  be  right ;  the  foliage 
and  2  specimens  are  S.  aurita  L — E.F.L. 
Populus  x  -  ?  (Ref.  No.  101).  Planted  along 
water-courses  between  Denston  and  Wickhambrook,  W. 
Suffolk,  v.c.  26,  May,  Sept,  and  Oct.  1912.  P.  serotina 
group,  but  distinct  from  P.  serotina  Hartig,  and  with 
smaller  leaves,  which  are  like  P.  nigra  italica ,  but  with  2, 
1,  or  0  glands  at  base  of  midrib,  and  of  a  pale  green  in 
spring,  contrasting  strongly  with  the  coppery  colour  of 
P.  serotina.  Faint  pubescence  quickly  vanishing  on  petiole, 
and  on  the  leaf-  The  tree  is  also  abundantly  planted  in
