R.  Reuteri,  God.  have  uniserrate  leaves,  while  these  are 
rather  strongly  biserrate.  The  fruit  is  young  to  determine 
the  direction  of  the  sepals,  but  the  general  look  of  the 
specimen  and  its  subglabrous,  not  woolly,  style  point  to 
the  Canina  group ;  for  British  authors  I  think  as  aggregate 
R.  dumalis  would  cover  it.  Continental  botanists  would 
perhaps  name  it  R.  insignis ,  Desegl.,  from  which  it  differs 
m  subglabrous  style,  or  R.  oblonga,  Desegl.,  which  should 
have  straighter  prickles. — A.  H.  W.-D. 
R.  glauca,  Vill.,  var.,  Watsoni ,  Baker.  Great  Stretton,. 
Leics.,  v.c.  55,  July  29,  1906.— C.  B.  Headly.  Not  Watsoni: 
intermediate  between  lutetiana  and  dumalis. — A.  Ley. 
Sepals  strongly  reflexed ;  leaves  very  slightly  compound- 
serrate.  Best  called  type  R.  canina  (lutetiana).— E.S.M. 
Not  Watsoni ,  Baker,  but  it  has  the  short  peduncles,  large 
bracts  and  the  stigmas  of  R.  glauca,  Vill.,  var.  subcristata, 
Baker.  For  certainty  it  should  be  gathered  later  when  the 
fruit  is  nearly  ripe.— W.  Barclay.  This  has  nothing  to  do 
with  R.  glauca  but  belongs  to  the  Biserratae  (dumalis) 
section.  I  see  no  reason  for  supposing  it  to  be  inter¬ 
mediate  between  that  and  R.  lutetiana.  R.  dumalis, 
Bechst.  is  not  so  strongly  biserrate  as  appears  to  be 
commonly  supposed,  and  many  examples  may  be  found 
named  on  good  authority  which  are  less  biserrate  than 
this.  It  agrees  closely  with  R.  cladoleia,  Rip.,  a  species 
closely  allied  to  R.  dumalis,  Bechst.  but  remarkably  un¬ 
armed,  and  with  nearly  glabrous  styles.  These  styles  are 
rather  hairy  but  less  so  than  in  average  dumalis. —

Epilobium  montanum,  L.  Old  masonry,  Sewage 
Works,  Leicester,  v.c.  55,  July  1906. — H.  P.  Reader  and 
W.  Bell.  There  must  have  been  thousands  of  similar 
plants  on  the  old  masonry  of  the  sewage  tanks.  None 
weie  over  15  inches  in  height,  while  many  were  not  more 
than  2  inches,  with  a  single  flower.  I  have  put  it  under 
E,  montanum ;  but  I  am  not  certain  whether  it  is  a  form
