arvense ,  var.  mite  Koch,  but  being  an  intermediate  form 
between  type  and  var.  setosum,  it  is  not  a  well  defined 
variety. — E.F.L. 
Hieracium  - .  Allt  Coire  Luidhearnaidh  (2500 
feet),  near  Dalnaspidal,  Mid  Perth,  v.c.  88.  (Ref.  No. 
3616);  also  from  a  stream  below  Coire  Chomlain,  Ben 
Alder  (Ref.  Nos.  3613,  3614),  and  from  the  Allt  an 
Locbain  Dbuibb,  between  four  and  fives  miles  north  of 
Cluny  Castle  (No.  3617),  E.  Inverness,  v.c.  96,  July,  1911. 
All  these  appear  to  be  the  same  species,  for  which  I 
have  no  name,  so  far;  but  it  seems  to  fit  in  best  with 
the  section  Alpina  Nigrescentia,  and  is  evidently  not 
uncommon  in  the  Badenocb  district,  growing  by  mountain 
streams  between  1800  and  2500  feet.  The  leaves  are 
flaccid,  hairy  on  both  sides,  light  green  in  shade,  often 
purplish  in  exposed  situations ;  primordial  root -leaves 
cuneate-based,  oval,  with  2-4  coarse  forward-pointing 
teeth  on  each  side,  the  rest  lanceolate  to  ovate-lanceolate, 
cuneate-based,  long-petioled,  with  3-4  sharp,  forward¬ 
pointing  teeth,  entire  or  nearly  so  in  their  upper  third, 
acute ;  stemleaf  one  (rarely  absent),  placed  near  or  (more 
commonly)  below  the  middle  of  the  stem,  linear-lanceolate 
or  lanceolate,  attenuate-acute,  with  about  3  sharp,  slender, 
forward-pointing  teeth  on  each  side,  gradually  narrowed 
into  a  more  or  less  winged  petiole,  often  a  bract-like  leaf 
occurs  above.  Stem  shaggy  below  with  white  hairs,  as 
are  the  petioles  and  leaf-margins.  Peduncles  floccose, 
with  a  good  many  stalked  glands  and  a  few  spreading 
white  hairs.  Heads  1  to  3  (rarely  4  in  large  specimens), 
cuneate  below;  phyllaries  linear,  somewhat  senescent, 
with  many  black-based  hairs  and  glands,  slightly  floccose 
below.  Styles  livid.  Ligules  medium-yellow ;  tips 
glabrous. — Edward  S.  Marshall.  There  i$  a  look  of 
Nigrescentia  about  the  foliage  of  these  plants,  but  not 
in  the  heads,  which  are  like  some  of  the  Silvatica.  It 
may  be  one  of  the  connecting  links  between  these  two 
groups.  I  have  no  name  for  it. — E.F.L.
