Potentilla  erecta  Harnpe,  [var.  sciaphila ].  Heath, 
Rangeworthy,  W.  Glos.,  v.c.  34,  July  29,  1914. — Ida  M. 
Roper.  My  Cornish  sheet,  so  named,  has  much  blunter, 
broader  leaves.  Only  small  type,  I  Relieve— E.S.M. 
P.  intermedia  L.  (fide  Kew).  Mildenhall,  W.  Suffolk, 
v.c.  26,  June  6,  1913  [see  Rept.  Watson  B.E.C.,  1913-14, 
p.  440). — W.  C.  Barton.  I  believe  so. — E.S.M.  Rouy  and 
Camus  (FI.  Fr.  VI.,  p.  193)  state  that  P.  intermedia  L. 
is  ambiguous,  and  use  the  name  P.  heptaphylla  Mill.  I 
do  not  know  enough  about  this  species  and  its  allies  to 
deny  that  the  plant  sent  belongs  to  this  species  ;  but  it  is 
the  fact  that  the  figure  of  P.  intermedia  L.  in  Reichen- 
bach’s  “  Icon.  Crit.”  t.  590,  has  flowers,  and  especially 
petals,  which  are  very  much  bigger  than  those  of  Mr. 
Barton’s  specimen.  The  leaflets,  too,  of  this  plant,  are 
more  deeply  cut  than  those  of  P.  intermedia  represented 
in  Reichenbach’s  work.  It  seems  to  me  that  this  specimen 
is  a  better  match  of  P.  obscura  Willdenow,  as  exemplified 
in  Reichenbach’s  “  Icon.  Crit.’’  t.  340.  Mr.  Barton  s  label 
does  not  indicate  whether  or  not  the  plant  is  indigenous — 
I  suppose  it  is  not.  I  found  a  single  plant— apparently  a 
seed-introduced  alien — like  Mr.  Barton’s  on  the  Greensand 
in  Cambridgeshire  in  July,  1915. — C.E.M. 
Acaena  Sanguisorbae  Vahl.  Banks  of  Tweed,  near 
Melrose,  Roxburghsh.,  v.c.  80,  Sept.  1914.  A  native  of 
Australia  and  New  Zealand,  a  wool  introduction  well 
established  by  the  Tweed.— I.  M.  Hayward. 
Rosa  involuta  Sm.,  var.  Wilsoni  (Borrer).  Growing- 
on  a  very  restricted  area  on  a  bank  at  the  edge  of  the 
Menai  Straits,  near  Bangor,  N.  Carnarvonsh.,  v.c.  49, 
Sept.  7,  1888. — Charles  Bailey.  Correct. — W.B. 
R.  omissa  Desegl.,  var.  (Ref.  No.  1  [1914] ).  Callar- 
fountain  Hill,  Perth,  Mid  Perthsh.,  v.c.  88,  Sept.  10,  1914. 
It  is  with  some  hesitation  that  I  place  this  rose  in  the 
Omissa  group.  While  it  is  evident  that  many  of  the 
sepals  persist  till  the  full  ripening  of  the  fruit,  others  had 
fallen  before  that  stage  was  reached,  and  taken  as  a 
whole  they  were  on  this  bush  certainly  not  so  persistent 
as  on  some  of  our  Scottish  forms.  Of  course  it  will  be 
understood  that  I  selected  specimens  which  still  retained 
their  sepals  at  least  in  part.  This  rose  borders  closely
