specimens  now  sent  seem  to  be  8.  caprea  x  viminalis — 
E.S.M.  I  think  S.  caprea  x  viminalis ,  but  a  rather  poor 
piece  of  foliage  for  certain  determination _ E.F.L. 
S.  arbuscula  L.  Beinn  Laoigb  (at  2500  feet),  Mid- 
Perthsh.,  v.c.  88,  July,  1911 _ P.  Ewing.  Yes _ E.F.L. 
Juniperus  [ sibirica  Burgsdorf] .  Ben  Heasgarnich, 
Mid  Perthsh.,  v.c.  88,  Sept.,  1910. — McT.  Cowan,  jun. 
Leaves  too  long  and  too  straight  for  that,  I  believe.  Is  it 
not  J.  communis  L.,  var.  intermedia  Nyman  (J.  intermedia 
Schur)  ?  My  Tongue  Bay  and  Little  Craigindal  specimens, 
so  named,  match  it  well — E.S.M.  Mr.  Cowan’s  plant  is 
apparently  one  of  those  which  have  been  distinguished  as 
var.  intermedia  Sanio  in  “  Deut.  Bot.  Monatschrf.”  I.  51 
(1888),  and  as  J.  intermedia  Schur,  in  “Verh.  Siebenb. 
Naturw.”  II.  169  (1850).  Mr.  Marshall’s  Tongue  Bay 
plant  seems  to  be  the  same  thing,  but  his  little  Craigindal 
specimen  seems  nearer  type.  I  have  recently  had  the 
extreme  form  of  J.  nana  with  short  leaves  sent  me  from 
Fair  Isle,  between  the  Orkney  and  Shetland  Is _ A.B.J. 
Pinus  sylvestris  L.  New  Forest,  S.  Hants.,  v.c.  11, 
April  22,  1911 — R.  S.  Standen.  This  has  considerably 
longer  leaves  than  my  native  specimens  of  the  Scotch  Fir, 
and  the  bark  is  different.  I  am  not  well  up  in  the  European 
species,  but  it  looks  like  the  Austrian  Pine  ( P .  nigricans 
Host). — E.S.M.  Undoubted  P.  sylvestris,  I  consider.  The 
Austrian  Pine  (P.  Laricio,  var.  austriaca)  has  longer  leaves 
and  quite  different  buds.  The  specimens  were  probably 
taken  from  a  fairly  young  tree,  which  would  account  for 
the  foliage  being  a  little  more  robust  than  usual.— A.B.J. 
Herminium  Monorchis  Br.  Harlington,  near  Luton, 
Beds.,  v.c.  30,  July  6,  1911 — Coll.  R.  Welsh.  Comm.  D.  M. 
Higgins. 
Potamogeton  polygonifolius  Pourr.,  var.  cordifolius 
Asch.  and  Graebn.  Ditch,  near  Loch  Tay,  Mid  Perthsh., 
v.c.  88,  Sept.,  1911 — McT.  Cowan,  jun.  Correct _ A.B. 
P.  [praelongus  Wulf.] .  Coniston  Lake,  N.  Lancs.,  v.c. 
69,  Sept.,  1911 — J.  Comber.  This  is  P.  angustifolius 
Bercht.  and  Presl.  (=  P.  Zizii  Koch).  It  is  a  characteristic 
specimen  of  the  var.  elongatus  Mert.  and  Koch  (sub  Zizii) 
Reich.  leones,  VII.  (1845)  24,  t.  39,  f.  68 _ A.B.
