Cystopteris  montana,  Link.  Ben  Laoigh,  Mid  Perthsh. 
v.c.  88,  July,  1907. — P.  Ewing. 
Polystichum  angulare,  Presl.,  var. - .  St. 
Gennys,  Cornwall,  v.c.  2,  Aug.,  1902.— Coll.  G.  B.  Dixon. 
Comm.  W.  Bell.  This  very  handsome  form  of  P.  angulare 
was  sent  to  me  by  Mr.  Dixon.  It  differs  considerably 
from  other  specimens  of  angulare  in  the  large  quantity  of 
scales  at  the  foot  of  the  petiole.  Is  it  one  of  the  named 
varieties? — W.  Bell.  This  appears  to  me  to  be  only  a 
small  form  of  P.  angulare.  I  doubt  if  the  scales  are  more 
numerous  than  is  usual  with  our  Cornish  plants. — F.H.D. 
I  fully  concur,  though  I  do  not  profess  to  know  Ferns 
well.—  E.S.M. 
LastrcBa  cemula ,  Brackenridge.  Hedge-bank,  Tonagh- 
more,  Saintfield,  co.  Down,  Sept.  7,  1907. — C.  H.  Waddell. 
Equisetum  arvense,  Linn.,  var.  alpestre,  Wahl.  Cam 
Chreag,  near  Killin,  Mid  Perthsh.,  v.c.  88,  July  18,  1907.— 
P.  Ewing. 
E.  variegatum,  Schleich.  Leasowe  Golf  Links, 
Cheshire,  v.c.  58,  June,  1907.— E.  and  H.  Drabble.  This 
has  nothing  to  do  with  variegatum ,  of  which  Newman’s 
arenarium  represents  the  type.  It  is,  I  believe,  small 
E.  palustre,  Linn. — E.S.M. 
E. - •  On  mud,.  Chard  Reservoir,  S.  Somerset, 
v.c.  5,  Sept.  16,  1907.  Stems  scabrid  at  the  angles. 
Central  tube  very  small,  exceeded  by  the  6-7  lateral  ones. 
This  has  mostly  been  referred  by  my  correspondents  to 
E.  palustre ;  but  one  of  them  sees  nothing  to  keep  it  from 
E.  arvense.  No  fructification  was  present.  The  station 
would,  I  think,  be  under  water  in  normal  seasons ;  this  is 
against  arvense ,  which  I  have  never  seen  in  very  wet 
situations.  The  habit  is  very  peculiar,  and  I  thought  that 
a  possible  solution  might  be  hybridity  between  these  two 
species.  In  any  case,  it  is  an  interesting  form. — E.  S. 
Marshall.  This  appears  to  be  a  form  of  E.  palustre  L. 
and  agrees  very  well  with  some  N.  American  specimens  so 
named  at  Kew. — A.B.J. 
Eycopodium  clavatum,  Linn.  Birchin  Grove  Wood, 
near  Luton,  Beds.,  v.c.  80,  Nov.  2,  1907.  Mr.  Saunders,
