Lilium  pyrenaicum  Gouan.  Thoroughly  established 
near  Molland,  N.  Devon,  v.c.  4,  May  81,  1912,  It  now 
occurs  in  a  second  station,  about  three-quarters-of-a-mile 
away  from  the  original  one.—  E.  S.  Marshall. 
Sparganium  simplex  Huds.  Hose,  Leics.,  v.c.  55,  July 
1912.  Rare  in  this  county _ A.  R.  Horwood.  Correct,  but 
when  this  is  given  as  “generally  distributed”  in  the  “FI. 
of  Leicester,”  (1886),  p.  156,  why  is  it  sent  ?  It  is  gathered 
far  too  early.  All  Spurgania  should  be  well  in  fruit  when 
gathered.  If  this  had  come  from  Scotland  it  would  not 
have  been  easy  to  name  it — A.B. 
Potamogeton  alpinus  Balb.  Lunan  Burn,  near  Marlee 
Loch,  E.  Perthsh.,  v.c.  89,  Aug.  1912.— McT.  Cowan,  junr. 
Yes.— A.B. 
p.  heterophyllus  Schreb.  Lunan  Burn,  at  Marlee 
Loch,  E.  Perthsh.,  v.c.  89,  Aug.  1912._McT.  Cowan,  junr. 
Yes,  correct.  With  it  are  fragments  of  P.  Sturrockii  Ar. 
Benn.,  thus  giving  another  locality  for  that  plant — A.B. 
P.  Lintoni  Fryer  (=  P.  crispus  x  Friesii).  Near  Shere, 
Surrey,  v.c.  17,  Aug.  81,  1912.— Mr.  W.  Biddiscombe  first 
discovered  this  interesting  plant  in  Surrey,  and  informed 
me  that  Mr.  Fryer  had  named  it  X  P.  Bennettii  (crispus  X 
obtusifolius).  Upon  examination,  however,  it  did  not  seem 
to  me  to  agree  well  with  the  plate  and  description  in  “Jl. 
Bot.”  1895, 1, particularly  in  the  leaf  veining,and  I  sent  fresh 
specimens  to  Mr.  A.  Bennett.  He  wrote— “I  should  name 
it  x  P.  Lintoni  Fryer,  as  the  leaf-apex  has  too  much 
serration  for  Bennettii.”— C.  E.  Salmon. 
P.  Sturrockii  Ar.  Benn.  Loch  Cluny,  E.  Perthsh.,  v.c. 
89,  Aug.  1912? _ McT.  Cowan,  junr.  Yes.  Although  made 
a  variety  otpusillus  in  the  last  ed.  of  Babington  s  Manual, 
it  is  a  good  sub-species.  As  yet  known  only  in  Scotland 
and  the  United  States  (where  it  is  rare). — A.B. 
P.  murinus  L.  Rescobie  Loch,  Forfarsh.,  v.c.  90,  Aug. 
1911.— McT.  Cowan,  junr.  Yes,  this  name  will  have  to  be 
used,  as  indeed  it  is  on  the  continent,  though  the  specimens 
so  named  in  the  Linnean  Herbarium  are  simply  pectinatus. 
I  shall  give  reasons  for  this  use  of  marinus  in  an  account 
of  the  genus  as  left  by  Linnaeus — A.B.
