R.  stylosa  Desv.,  var.  leucochroa  (Desv.).  Hedge, 
Sea  Mills,  Bristol,  W.  Glos.,  v.c.  34,  June  20  and  Sept.  25, 
1911.  The  petals  are  pure  wThite. — Ida  M.  Roper. 
Resembles  the  S.  Devon  plant  called  R.  leucochroa  Desv. ; 
but  I  have  only  observed  the  living  plant  when  in  flower. 
— E.S.M.  Correct  for  the  true  plant  of  Desvaux,  i.e., 
R.  systyla  with  white  flowers.  Not  the  R.  leucochroa  of 
British  botanists. — A.H.W.-D.  Not  R.  leucochroa  Desv. 
as  described  in  “FI.  Plym.,”  pp.  141-2  (cf.  “  Bot.  Exch. 
Cl.  Rept.”  1888,  pp.  216-7);  but,  I  believe,  R.  pseudo- 
rusticana  Crep.  Both  are  locally  frequent  in  S.W. 
England  ( leucochroa ,  Cornwall  to  Hants.;  pseudo -rusticana 
Devon  to  Wilts.) ;  pseudo -rusticana  being  the  more  thinly 
distributed.  It  is  described  in  B.E.C.  Rept.  1889,  pp.  23, 
24 ;  and  though  the  specimen  sent  is  not  a  strikingly 
characteristic  example  of  it,  I  see  no  reason  for  doubting 
the  correctness  of  the  name.  I  have  never  met  with  a 
hush  that  seemed  to  me  intermediate  between  it  and 
leucochroa.  The  right  place  for  the  latter  seems  to  be 
between  R.  obtusifolia  Desv.  and  R.  systyla  Bast.,  while 
p seudo -rustic ana  comes  in  best  between  R.  systyla  and 
R.  arvensis  Huds.  This  is  the  first  Gloucestershire 
specimen  of  pseudo -rusticana  that  I  remember  to  have 
seen  ;  but  leucochroa  is  recorded  for  v.c.  33  (E.  Glos.)  in 
Jl.  Bot.  1911,  p.  252. — W.M.R.  Mr.  Moyle  Rogers  knows 
this  group  so  well  that  his  opinion  as  to  its  relationship 
to  var.  pseudo -rusticana  is  probably  correct. — W.B. 
Gratcegus  monogyna  Jacq.,  var.  glabrata  Sonder.  ( fide 
A.  Bennett).  Dalmeny,  Linlithgowsh.,  v.c.  84,  May  27, 
1911 . — McT.  Cowan,  junr. 
Saxifraga  Geum  L.  (Ref.  No.  3639).  Near  Cloghane, 
S.  Kerry,  June  16,  1911.  These  specimens  have  foliage 
less  sharply  toothed  than  in  the  usual  Irish  form  (var. 
serrata  Syme),  thus  approaching  the  type;  though  I 
have  seen  Kerry  plants  with  much  more  obtuse  serration, 
and  hardly  separable  from  the  prevailing  Pyrenean  form 
which  is  cultivated  in  our  gardens. — E.  S.  Marshall. 
Between  S.  Geum  and  var.  dentata  ;  such  forms  are  not 
unfrequent  in  Co.  Kerry. — E.F.L. 
S.  umbrosa  L.,  var.  serratifolia  D.Don.  (Ref. 
No.  3648).  Connor  Hill,  S.  Kerry,  June  19,  1911.  A  f$w
