Right. — E.F.L.  (2)  Meall  nan  Tigearn,  near  Dalmally, 
Argyllsh.,  v.c.  98,  at  or  below  2000  feet,  July  20,  1910. 
Styles  yellow.  Very  typical.— E.  S.  Marshall. 
H.  ckrysanthum  Backh.  Ben  More,  Mid  Perth,  v.c. 
88,  at  about  3000  feet,  July  16,  1910.  Quite  typical. 
Styles  yellow. — E.  S.  Marshall.  Correctly  named. — E.F.L. 
H.  nigrescens  Willd.  (Ref.  No.  3494).  Ben  a’ 
Bhuiridh,  near  Dalmally,  Argyllsh.,  v.c.  98,  at  or  over 
2000  feet,  on  granite,  July  12,  1910.  Styles  very  dark; 
ligule-tips  sub-glabrous ;  heads  thickly  clothed  with  black 
gland-tipped  hairs,  epilose,  stem -leaf  occasionally  rather 
large.  It  clearly  belongs  to  the  section  Alpina  Nigres- 
centia.  I  believe  it  to  be  pretty  typical  H.  nigrescens. — 
E.  S.  Marshall.  I  agree  to  these  specimens  as  H. 
nigrescens  Willd. — E.F.L. 
H.  Leyi  F.  J.  Hanb.  (1)  Cliffs  of  High  Street, 
Westmorland,  v.c.  69,  July  2,  1910.  The  plant  sent  is 
abundant  (with  much  variation  in  size  and  leaf-toothing), 
not  only  on  the  cliffs  of  High  Street,  but  also  on  those 
of  Helvellyn,  Westmorland.  The  late  Rev.  W.  R.  Linton, 
who  gathered  it  on  Helvellyn  and  Fairfield,  Westmorland, 
in  1905,  was  inclined  to  ascribe  it  to  a  variety  of  H. 
Sommerfeltii  Lindeb. ;  but  after  studying  it  in  situ  this 
year,  I  believe  it  must  be  placed  under  H.  Leyi  F.  J. 
Hanb.— A.  Ley.  Less  glandular  than  usual ;  but  I  agree 
to  the  name. — E.F.L.  (2)  Dollywaggon- Pike,  Westmor¬ 
land,  v.c.  69,  July  8,  1910.— A.  Ley.  Differing  a  little 
from  the  High  Street  plant,  in  leaves  moie  coriaceous, 
and  heads  less  hairy,  but  I  think  both  are  H.  Leyi  —
