rugose  leaves,  woolly  beneath,  and  slender  subsimple  spikes 
of  my  specimen  show  no  sign  of  any  other  species.— 
E.F.L.  Double  hybrids  are  very  difficult  to  distinguish 
unless  studied  in  situ.  Doubtless  there  is  in  this  the 
peculiar  pungent  smell  of  spicata,  and  the  spikes  are 
more  suggestive  of  that  species,  whilst  the  leaves  suggest 
rotundi folia. — A.B . 
M.  spicata  L.  (1)  Hicks  Mill,  Gwennap,  W.  Cornwall, 
v.c.  1,  Aug.  2,  1911.  Whole  plant  more  robust,  leaves 
broader,  whorls  of  flowers  more  contiguous  than  I  am 
accustomed  to. — F.  H.  Davey.  Another  puzzle !  The 
glabrous  corolla  is  right  for  spicata,  but  the  leaves,  stem, 
etc.  are  much  too  hairy,  and  the  shape  of  the  leaves 
suggests  sylvestris.  Can  it  be  spicata  x  sylvestris  ? — 
C.E.S.  Is  not  this  M.  longifolia  x  spicata  ? — E.F.L. 
This  is  far  too  hairy  for  M.  spicata,  pure  and  simple  ; 
apparently  it  is  M.  longifolia  x  spicata. — E.S.M.  I  think 
correct,  but  the  leaves  are  less  subsessile  than  usual.  It 
might  possibly  be  M.  longifolia  x  spicata,  but  I  doubt  it. 
— A.B.  (2)  Cult.  Edmondsham,  Dorset,  Sept.  17,  1911. 
Sent  me  by  some  one,  and  no  note  preserved.  It  seems 
to  have  rather  short  and  wrinkled  leaves  for  the  species. 
— E.  F.  Linton.  The  upper  leaves  are  very  rugose  on 
both  surfaces ;  this  and  other  characters  lead  me  to 
regard  it  as  a  glabrate  M.  rotundifolia  x  spicata.  —E.S.M. 
I  should  rather  agree  with  Mr.  Marshall,  but  cultivated 
specimens  are  deceptive  sometimes.  It  is  not,  I  think,

M.  sativa  L.  ;  a  very  hairy  form,  with  the  aquatica  habit. 
—A.B.  I  believe  so ;  but  on  the  aquatica  side,  and  perhaps 
with  a  double  dose  of  that  species  in  it.  The  calyx-teeth 
are  mostly  linear-subulate  or  linear-lanceolate ;  not 
triangular-lanceolate,  as  in  the  first  cross  (M.  sativa  L.) 
—E.S.M.  Yes,  I  think  so;  the  form  rivalis  (i.e.  on  the 
arvensis  side).  My  specimen  must  be  different  to  those 
received  by  Messrs.  Marshall  and  Bennett,  as  the  habit 
is  totally  unlike  that  of  aquatica\ — C.E.S.
