(Dec.  11,  1918)  that  he  believed  it  to  be  T.  elatum  Jacquin, 
and  that  he  had  seen  not  only  Jacquin’s  description  and 
figure,  but  also  his  specimen.  T.  elatum ,  however,  seems 
to  be  a  plant  of  Austria  and  S.E.  Europe,  not  known  for 
Scandinavia ;  so  its  occurrence  in  Britain  would  be  a 
geographical  puzzle. — Edward  S.  Marshall.  Mr.  N.  E. 
Brown  (“  Suppl.  E.  B.”  p.  4,  1892)  distinguishes  this 
species  chiefly  by  its  longer  pedicels,  together  with  the 
larger  size  of  the  leaves  and  of  the  whole  plant.  Mr. 
Marshall’s  specimen  has  these  features ;  I  should  name 
it  T.  majus  Crantz. — E.F.L.  So  far  as  I  can  judge,  this 
is  T.  elatum  Jacquin.  I  base  my  opinion  on  Jacquin’s 
original  description,  his  large  original  figure,  and  his 
type-specimen  (in  Herb.  Mus.  Brit.).  Mr.  Marshall’s 
remarks  on  the  distribution  of  T.  elatum  appear  to  be 
based  on  that  as  given  by  Nyman  and  others;  but  have 
these  authorities  seen  Jacquin’s  specimen?  The  plant 
that  passes  for  “  T.  elatum  Jacquin”  on  the  mainland  of 
Europe  is  not,  me  judice,  Jacquin’s  plant  at  all ;  and  the 
distribution  cited  by  Mr.  Marshall  applies  to  T.  elatmn 
auct.  non  Jacquin.  I  have  known  the  plant  (T.  elatum 
Jacquin  me  judice)  for  twenty  years  as  occurring  locally 
on  the  margins  of  lakes  in  the  Lake  District  and  in 
Scotland.  Formerly  I  regarded  it  as  T.  majus  ;  and  it 
is  without  doubt  the  T.  majus  of  many  British  botanists, 
but  not,  according  to  my  present  opinion,  of  Jacquin  or 
of  Smith  “  Eng.  Bot.”  Jacquin  originally  described  his 
plant  from  a  garden  specimen.  There  is  nothing  in  the 
British  distribution  of  this  lowland  plant  to  suggest  that 
it  should  not  occur  in  central  Europe.  I  should  add  that 
I  do  not  for  a  moment  believe  the  plant  to  be  T.  majus, 
var.  capillare  N.  E.  Brown  (=  T.  capillare  Reichenbach). —

Ranunculus  circinatus  Sibth.  The  Lake,  Southill 
Park,  Beds.,  v.c.  30,  June  28,  1913.  Dr.  Moss  tells  me 
that  this  plant  is,  in  his  experience,  more  usually  found 
in  moving  water. — J.  E.  Little.  Correct.—  E.S.M.  Seems 
typical. — J.G.

Benfleet,  S.  Essex,  v.c.  18,  April,  1913. — W.  R.  Sherrin. 
Apparently  a  form  of  R.  heterophyllus  Weber,  without 
floating  leaves;  it  may  be  var.  submersus  (Hiern). — E.S.M.
