Agropyron  [pungens  R.  &  S.,  var .pycnanthum  G.  &  G.] . 
(Ref.  No.  50).  Albecq,  Guernsey,  Aug.  16,  1912. — W.  C. 
Barton.  I  suppose  so. — B.S.M.  I  believe  correct. — A.B. 
A.  repens  x  junceum . — E.  Hackel. 
Cystopteris  fragilis  Bernh.,  var.  dentata  Hook  (Ref. 
No.  3748).  Frequent  in  Cwm  Idwal,  Carnarvonsh.,  v.c.  49, 
July  13,  1912. — Edward  S.  Marshall. 
Equisetum  arvense  L.,  var.  alpestre  Wahl.  Beinn 
Laoigh  (at  2500  feet),  Mid  Perthsh.,  v.c.  88,  July  1912.— 
P.  Ewing.  Yes;  I  have  gathered  it  there. — E.S.M. 
Wahlenberg’s  description  of  this  is,  “ /3  alpestre  caulibus 
sterilibus  decumbentibus”  ;  “at  /3  latera  alpium  inferiora 
saepius  frequentat  habitu  longe  alieno  notabile.”  (“FI. 
Lapp.,”  p. 296,  1812).  Ledebour  “FI.  Ross.”  iv,  p.  486  (1853), 
gives  a  much  longer  description  of  a  var.  alpestre ,  but  does 
not  refer  to  Wahlenberg;  whether  they  represent  the  same 
plant  I  do  not  know.  But  do  these  plants  belong  to 
arvense  ?  They  do  not  accord  with  specimens  from 
Shetland  named  alpestre  for  Mr.  Beeby  by  Prof.  Lange 
— do  they  not  belong  to  E.  pratense  ? — A.B. 
Isoetes  hystrix  Durieu.  Damp  ground,  near  Fort  La 
Marchant,  Guernsey,  Aug.  8,  1912.— W.  C.  Barton.  Dr. 
Syme  in  “English  Botany,”  ed.  iii,  describes  the  plant  as 
with  leaves  1^  to  2|-  inches  long,  but  in  specimens  gathered 
in  Guernsey  by  Mr.  W.  W.  Reeves  (June  18,  1885)  they  are 
6  inches  long. — A.B.

Chara  hispida  L.  Marsh  ditch,  Kenn  Moor,  N. 
Somerset,  v.c.  6,  Sept.  28,  1903. — J.  W.  White.  A  small 
form  with  the  habit  of  C.  vulgaris. — A.B. 
Nitella  gracilis  Agardh.  Perranzabuloe,  W.  Cornwall, 
v.c.  1,  Dec.  1912.— Coll.  F.  Relstone.  Comm.  F.  H.  Davey.
