H.  sciaphilum  Uechtr.,  var.  trcmsiens  Ley.  (Ref.  No. 
160).  Arthog  (at  200  feet),  Merionetbsh.,  v.c.  48,  -July  29, 
1915. — W.  C.  Barton.  Yes,  var.  trcmsiens  Ley  ( see  “Jl. 
Bot.”,  1909,  p.  49). — E.F.L. 
H.  protractum  Lindeb.  Origin,  Unst  (-J.  Groves), 
Shetland,  v.c.  112,  cult.  Ledbury,  July  15.  1915. — S.  H. 
Bickham. 
H.  gothicum  Ft.,  var.  latifolium  Backh.  (Ref.  No. 
4099).  Very  local  on  grassy  cliffs,  Melvich,  W.  Sutherland, 
v.c.  108,  Aug.  7,  1915.  Styles  yellow,  or  occasionally 
livescent.  Ligules  glabrous-tipped.  I  think  this  a  fairly 
good  variety.  The  type  does  not  occur  there. — Edward  S. 
Marshall.  Rightly  labelled  var.  latifolium  Backh.,  and  not 
as  in  the  Lond.  Cat.,  f.  latifolia.  The  aggregation  of  the 
leaves  at  the  base  of  the  stem  is  a  frequent  feature  in  the 
variety.— E.  F.  L. 
H.  boreale  Fr.,  var.  rigens  (Jord.).  (Ref.  No.  181). 
Lake  Gwernan,  near  Dolgelley.  (Ref.  No.  180).  Gwynant 
Valley,  near  Penmaenpool,  Merionetbsh.,  v.c.  48,  Aug.  24 
and  31,  1915. — W.  C.  Barton.  Though  not  agreeing 
perfectly  with  H.  rigens,  -Jord.,  it  seems  to  come  nearest 
that,  and  is,  I  think,  the  British  form  so  named  from 
N.  Wales  and  other  parts  of  Britain.  No.  180  being 
practically  identical  with  No.  181  may  have  the  same 
note  attached  to  it. — E.F.L. 
H,  umbellatum  L.,  var.?  (Ref.  No.  170,  171).  On 
refuse  from  slate  quarries,  Betliesda,  Carnarvonsh.,  v.c.  49, 
Aug.  17,  1915.  The  Rev.  E.  F.  Linton  writes:  “  H.  umbel- 
latum  L .,  a  neat-looking  form  with  leaves  reduced  in  size 
and  length  and  often  aggregated  near  the  base  ;  a  variation 
probably  induced  by  the  situation  and  lack  of  richer  soil, 
which,  if  cultivated,  would  become  normal.  Hardly  any 
of  the  specimens  shew  squarrose  phyllaries.  These 
remarks  include  Nos.  170  and  171.”  Besides  the  character¬ 
istics  noted  above  I  was  struck  by  the  rigidity  of  stem 
and  leaves  and  the  brittleness  of  the  stem.  The  plant 
was  easily  distinguished  by  its  habit,  and  by  the  reddish 
colour  of  the  stems. — W.  C.  Barton.  Yes.  Forms  of 
H.  umbellatum  with  heads  (when  dry)  as  black  as  in 
H.  boreale. — E.S.M.
