pure  white. — C.  H.  Waddell.  I  think  the  present 
specimens  are  laxer,  wider-spaced  and  more  flexuous  than 
those  I  saw  formerly,  but  that  may  be  from  situation  and 
age.  The  bark  is  not  at  all  darker  than  in  many,  if  not 
most,  Scottish  specimens.  All  I  can  say  of  it  is  that  it 
appears  to  be  R.  tomentosa  8m.,  of  group  Omissa  Desegl, — 
W.B.  An  Omissci  form  nearest  var.  submollis  Lev. —

R.  Borreri  Woods.  Little  Malvern,  Worcs.,  v.c.  37, 
Aug.  18,  1915. — A.  J.  Crosfield.  Yes,  =  R.  tomentella 
Lem. — W.B.  Hardly  strong  enough,  and  no  peduncles 
glandular,  nor  are  the  leaves  glandular  beneath.  I  should 
label  it  R.  Carionii  Desegl.  &  Ozan. — A.H.W.-D. 
R .  canina  L.,  var.  \lutetiana  (Leman)] .  (Ref.  No.  12).

Petals  white ;  a  strong  bush. — C.  H.  Waddell.  This  is  a 
form  of  R.  dumetorum  Thuill. — a  thinly-hairy  form  which 
may  be  called  var.  urbica  Lem.’— W.B.  Too  thinly-hairy 
even  for  R.  urbica.  It  should  be  placed  under  R.  semiqlabra 
Rip.— A.H.W.-D. 
R.  canina  L.,  var.  dumalis  (Bechst.),  form  with 
spherical  fruit.  (Ref.  No.  13).  Mountstewart,  Co.  Down, 
Oct.,  1915.  A  tall  vigorous  bush. — C.  H.  W^addell.  This 
also  is  a  thinly-hairy  form  of  R.  dumetorum  Thuill.,  but 
with  globular  fruit.  It  is  in  no  material  respect  different 
from  No.  17,  which  is  called  R.  dumetorum ,  var.  sphcero- 
carpa  Pug.  This  variety  is  described  as  having  unarmed 
petioles  and  thinly  hispid  styles.  No.  17  has  some  petioles 
unarmed,  some  slightly,  and  some  strongly  armed,  and  its 
styles  are  densely  hispid  or  rather  villous.  I  believe 
R.  opaca  Gren.,  R.  globata  Desegl..  and  some  other  globose- 
fruited  forms  would  fit  it  just  as  well,  so  that  there  is  a 
choice  of  names.  R.  dumetorum,  var.  urbica,  with  globose 
fruit,  satisfies  me.— W.B.  Nothing  to  do  with  R.  dumalis, 
hut  one  of  the  Dumetorum  sub-group.  The  globose  fruit 
is  not  against  R.  dumetorum  Thuill.,  though  British 
botanists  usually  assign  ovoid  fruit  thereto,  but  its  leaflets 
are  too  broad  and  too  thinly  hairy,  and  its  styles  too 
hispid.  I  should  label  it  R.  platyphylla  Rau. — A.H.W.-D. 
R.  dumetorum  Thuill.,  var.  splicerocarpa  (Pug.).  (Ref. 
No.  17).  Hedge,  Grey  Abbe}-,  Co.  Down,  Sept.  2,  1915. —
