Spergula  arvensis,  L.,  var.  sativa  (Bcenn).  Ponsanooth, 
W.  Cornwall,  v.c.  1,  Oct.  12,  1905.  Around  Ponsanooth 
this  form  is  quite  as  common  as  S.  arvensis ,  L.,  and  both 
grow  together. — F.  H.  Davey.  The  seeds  are  without 
papillae,  but  I  have  never  seen  sativa  so  nearly  eglandular ; 
usually  it  is  densely  viscid. — E.S.M.  I  agree. — E.F.L. 
Hypericum  undulatum ,  Schousb.  Ponsanooth,  W. 
Cornwall,  v.c.  1,  Sept.  8,  1905. — F.  H.  Davey.  Good 
examples. — E.F.L. 
Acer  campestre,  L.,  var.  leiocarpon,  Wallr.  Scraptoft,.

TJlex  Gallii ,  Planch.,  var.  humilis,  Planch.  Gwennap, 
W.  Cornwall,  v.c.  1,  Oct.  14,  1905. — Abundant  on  exposed 
downs  all  over  the  county,  but  not  previously  recorded  as 
a  distinct  variety.  The  old  records  for  U.  nanus ,  Forster, 
are  clearly  referable  to  this  plant,  as  that  species  is  still 
unknown  for  the  mainland,  although  Mr.  A.  Somerville 
has  presented  me  with  an  undoubted  specimen  from  the 
Scilly  Isles.  I  am  indebted  to  Mr.  Arthur  Bennett  for 
Planchon’s  description  : — “  var.  /3 .  humilis ,  depressed, 
branches  humifuse,  branchlets  and  leaves  crowded ; 
flowers  a  little  smaller  than  in  the  typical  race.”  Ann. 
des  Sc.  Nat.,  April,  1849,  p.  218.  The  plant  cannot  be 
easily  mistaken.  It  grows  in  dense  patches  about  eighteen 
inches  high,  over  which  one  can  walk  without  touching 
the  ground.  The  primary  spines  are  shorter  than  in  the 
type,  and  more  densely  branched  at  the  base.  Young 
shoots  from  plants  which  have  been  cut  down,  or  destroyed 
by  fire,  lie  close  to  the  ground,  and  are  furnished  with  a 
greater  number  of  flowers  than  older  branches. — F.  H. 
Davey. 
Medicago  denticulata,  Willd.  forma - .  (Nos.  1142 
&  1157).  Wool  aliens.  Galashiels,  Selkirksh.,  v.c.  79,  Oct., 
1904. — Coll.  W.  Shaw.  Comm.  E.  S.  Gregory.  Medicago 
denticulata ,  Willd. — E.F.L. 
M . - .  (No.  1152).  Growing  wild  in  garden  at 
Galashiels,  Oct.  1904. — Coll.  W.  Shaw.  Comm.  E.  S. 
Gregory.  M.  denticulata ,  Willd. — E.F.L.
