***  A  few  plants  that  were  unaccompanied  by  notes 
or  critical  comments  have  been  omitted  from  the  Report. 
Thalictrum  collinum,  Wallr.  Plantation  near  Devil’s 
Ditch,  Cambs.,  v.c.  29,  July  12,  1906. — Coll.  R.  H.  Goode. 
Comm.  G.  Goode.  This  is  in  flower  only  ;  fruit  is  necessary 
for  a  proper  determination.  No  doubt,  however,  it  is  the 
T.  saxatile  Bab.,  now  referred  to  T.  collinum  Wallr. — E.S.M. 
This  name  may  stand  for  a  flowering  specimen.  But  ripe 
fruit  from  these  Cambs.  plants  shows  that  there  are  two 
forms  among  them,  one  with  the  ordinary  T.  collinum  fruit 
(oblique  oblong),  and  another  with  the  evenly  ovoid  fruit 
that  distinguishes  T.  Kochii  Fr.  I  have  sown  seeds  of 
both  forms  to  see  if  they  keep  their  character. — E.F.L. 
T.  fiavum,  L.,  var.  nigricans ,  Jacq.  In  large  masses 
in  several  spots  near  Llangorse  Lake,  Breconsh.,  v.c. 
42,  July  26,  1906. — The  black  coloration  of  foliage  and 
stem  was  conspicuous  even  in  the  fresh  plant,  and  has 
become  more  marked  when  dried.  The  fruits,  as  usual, 
are  often  distorted  and  swollen  by  insects,  but  when  not 
so,  shew  the  outline  of  this  variety  fairly  distinctly. — 
Augustin  Ley.  A  similar  plant  was  named  T.  gallicum 
Rouy  &  Foucaud  by  Herr  Freyn. — E.S.M.  I  have  known 
the  plant  under  this  name  in  the  past,  but  cannot  find  out 
what  T.  nigricans  Jacq.  is.  Rouy  and  Foucaud  (FI.  de 
France)  do  not  give  it,  though  mentioning  T.  nigricans 
for  two  plants  as  “non  Jacq.”  Herr  Freyn  named  it 
T.  gallicum  Rouy  and  Foucaud  for  another  Club,  at  the 
same  time  that  I  suggested  T.  rufinerve  Lej.  and  Court. 
(T.  nigricans  auct.  Gall,  occid.  non  Jacq.) ;  but  T.  gallicum 
is  a  plant  very  stoloniferous,  with  long  stolons  (FI.  de 
France  I.  29),  and  Herr  Freyn  did  not  have  roots ;  whereas 
I  know  from  years  of  cultivation  that  it  is  densely 
cespitose.  It  is  very  shy  of  producing  seed  of  any  sort  in 
the  garden.  If  Mr.  Ley  could  get  honest  fruit  it  might 
help  much  towards  a  fresh  determination.  Meanwhile  it 
fits  Rouy  and  Foucaud’s  description  of  T.  rufinerve  fairly 
well. — E.F.L. 
Ranunculus  peltatus,  var.  - .  Pond  near 
Bracklebridge,  Leics.,  v.c.  55,  June  1906. — W.  Bell  and 
H.  P.  Reader.  Good  R.  heterophyllus,  Web. — E.S.M.  This 
we  prefer  to  put  under  R.  heterophyllus ,  Web.  in  spite  of 
one  of  the  specimens  having  a  long  peduncle. — H.  and  J.G.
