P.  maculatum ,  var.  densum,  Trim,  and  Dyer — Waste 
ground,  Coe  Fen,  Cambridge,  v.c.  29,  6  Sept.,  1904. — E.  J. 
Allard.  This  is  P.  maculatum,  Trim,  and  Dyer,  and  if  the 
vars.  are  worth  distinguishing  this  may  be  called  densum . 
But  I  think  our  principal  Floras  and  the  “London  Catalogue” 
are  right  in  ignoring  these  varieties;  even  Mr.  Druce  (FI. 
Berks.)  refers  to  them  only  as  forms. — -E.F.L. 
P.  Bistovta,  L.  Windermere,  Westmorland,  v.c.  69, 
7  June,  1904. — Coll.  W.  Barratt  Comm.  F.  H.  Davey. 
Rumex  scutatus,  L.  Craigmillar  Castle,  Midlothian, 
v.c.  83,  24  June,  1904 — F.  C.  Crawford. 
Asavum  europeeum ,  L.  Chalk  Lane,  Redlynch,  near 
Salisbury,  S  Wilts.,  v.c.  8,  15  May,  1904 — F.  L.  Foord- 
Kelcey. 
Salix  triandra,  L.,  var  Hoffmanniana ,  Sm.  Bank  of  R. 
Wye,  near  Sellack,  Herefordshire,  v.c.  36,  16  May  and 
2  Aug.,  1904.  — S.  H.  Bickham.  Correct. — E.F.L. 
S.  triandra  x  viminalis  (Jtippophce folia,  Wimm.  et.  Grab.). 
Bank  of  Wye,  near  Sellack,  Herefordshire,  v.c.  36,  16  May 
and  2  Aug.,  1904  —  S.  H.  Bickham.  Yes.  S.  hippopha folia, 
Thuill. — E.F.L. 
5.  fragilis  x  alba  (viridis,  Fr.).  Malvern  Link,  Wor¬ 
cestershire,  v.c.  37,  5  May  and  26  Aug.,  1904. — S.  H. 
Bickham  and  R.  F.  Towndrow.  I  believe  the  late  Dr. 
Buchanan  WRite  thought  the  tree  from  which  these  speci¬ 
mens  were  gathered  to  be  5.  viridis .  I  send  a  couple  of 
specimens  on  the  chance  that  it  may  be  worth  while  to  gather 
more. — S.H.B.  The  chief  peculiarity  about  this  form  is  the 
breadth  of  the  leaves,  which,  however,  is  not  a  feature  of 
S.  alba.  In  a  male  specimen  like  this  there  is  not  much  to 
go  by,  and  I  should  prefer  to  call  it  S.  fragilis  form,  as  I  see 
no  distinct  trace  of  S.  alba  in  it.  The  young  foliage  is 
rather  less  silky  than  average  S.  fragilis,  and  in  S.  viridis  it 
should  be  more  so.  Mr.  Bickham  is  apparently  right  in 
identifying  this  tree  with  one  sanctioned  by  Dr.  B.  White  as 
5.  viridis.  I  have  similar  specimens  gathered  by  Mr.  R.  F. 
Towndrow  in  May  and  Aug.,  1889,  and  accepted  by  Dr 
White  as  “  a  good  intermediate  condition  ”  (of  5.  viridis  Fr.) 
in  B.  E.  C.  Report,  1889,  p.  268,  but  I  have  transferred 
them  to  S.  fragilis  type.— E.F.L. 
S.  fragilis  x  alba  (viridis,  Fr.).  Link  Elms,  near  Malvern, 
Worcestershire,  v.c.  37,  5  May  and  29  Aug.,  1904 — S.  H. 
Bickham.  I  call  this  also  61.  fragilis  type  ;  and  while  the
