type  neglecta  :  how  is  that  distinguished  from  umbrosa  ? 
— C.E.S.  We  have  in  Britain  three  distinct  forms  : — 
1.  S.  neglecta ,  Weihe.  Pedicels  and  calyx  hairy; 
seeds  acutely  tubercled. 
2.  S.  umbrosa ,  Opiz.  (S.  Elisabethae  F.  Schultz, 
apparently).  Like  the  above,  but  with  quite  glabrous 
pedicels  and  calyx. 
8.  S.  neglecta ,  var.  decipiens.  Like  neglecta  but  for 
the  bluntly  tubercled  seeds.  Habit  usually  rather  different 
— nearer  S.  media. 
I  consider  S.  umbrosa  (our  usual  form,  at  least  in  the 
West,  and  by  far  the  most  markedly  different  from  S. 
media )  the  true  “type”  of  the  species;  but  one  has  to 
accept  the  Vienna  rulings,  so  our  arrangement  must  be  :— 
S.  neglecta ,  Weihe. 
b.  var.  umbrosa  (Opiz). 
c.  var.  decipiens ,  mihi.  =  S.  neglecta  Auct.  angl. 
(non  Weihe). — E.S.M. 
S.  media ,  Cyr.,  var.  neglecta,  Weihe.  Narborough, 
Leics.,  v.c.  55,  May  19,  1906.— C.  B.  Headly.  Var. 
decipiens,  Marshall,  I  think. — S.H.B.  There  are  no  ripe 
seeds  on  my  specimen  ;  but  those  which  are  present  look 
as  if  they  would  be  bluntly  tubercled  when  mature,  and 
the  habit  is  that  of  S.  neglecta,  Weihe.,  var.  decipiens, 
rather  than  of  typical  S.  neglecta.— E.S.M.  Tubercles 
rather  rounded  (compare  with  Croxton  plant).  Pedicels 
and  calyx  hairy ;  pedicels  not  longer  (apparently)  than 
flowering- calyx.  Yes,  I  suppose  a  var.  of  media  (the  one 
which  we  have  been  calling  neglecta)  but  which  Mr. 
Marshall  calls  either  “neglecta,  var.  decipiens ,”  or  “ umbrosa , 
var.  decipiens .”  Mr.  Townsend  (FI.  Hants.,  ed.  II.,  629) 
says  that  he  cannot  place  neglecta,  “as  Mr.  Marshall  does, 
with  S.  umbrosa ,”  but  keeps  it  as  a  var.  of  media. — C.E.S. 
Arenaria  serpy lli folia,  L.,  var.  leptoclados  (Guss.). 
Woodhouse  Eaves,  Leics.,  v.c.  55,  June  19,  1906.— C.  B. 
Headly.  Not  the  variety  ;  type.— S.H.B.  and  A.L. 
Elatine  hexandra,  DC.  Begbush  Pond,  W.  Sussex, 
v.c.  18,  Aug.  16,  1906. — -H.  S.  Thompson.  I  daresay  right: 
I  see  two  flowering-specimens  of  Scirpus  acicularis 
attached. — E.F.L.  Seeds  only  slightly  curved;  so  it 
appears  to  be  correct.  Mixed  with  it  I  find  three  flowering-
