drop  that  name  and  use  “ M.longifolia  x  aquatica  ( M.dume - 
torum.  M.  nepetoides) .”  Curiously  they  write  “Merita.” 
Malinvaud,  in  his  “  Revision  des  Menthes  de  l’herbier  de 
Lejeune  ”  (Bull.  Soc.  Linneenne  de  Normandie,  Ser.  III., 
Vol.  8,  1878-9,  p.  15),  mentions  that  there  are  in  that 
herbarium  seven  specimens  of  M.  nepetoides  Lej.,  one  of 
which  served  Lejeune  for  his  principal  description  of  the 
plant.  Lejeune  wrote  on  the  label  “  Mentha  nepetoides , 
specimen  in  Revue  descriptum — ad  M.  dumetorum  Com- 
pend.  pertinere  videtur  secundum  Nees  junior.”  On  this 
Malinvaud  remarks,  “  Le  Compendium  ici  mentionne  est 
celui  de  Bluff  et  Fingerhuth  (II.,  p.  11-12,  1825),  et  la 
description  qu’on  y  trouve  du  M.  dumetorum  Schult.  est 
applicable  au  M.  nepetoides,  ainsi  que  la  remarque  suivante 
qui  la  termine :  *  ad  M.  palustrem  Sole  propius  accedere 
videtur.’  En  resume,  les  M.  palustris  Sole,  nepetoides 
Lej.,  dumetorum  Schult.,  pubescens  et  hirta  Willd.  sont, 
sous  divers  noms,  des  formes  hybrides  de  M.  silvestris  et 
aquatica .”  ( See  also  B.E.C.  Rept.,  1887,  p.  187 ;  1889,

M.  [| gracilis  Sm.,  var.  cardiaca  Baker] .  Garden,  Castle- 
acre,  Norfolk,  Sept.  1911 _ F.  Long.  This  is,  I  think, 
quite  good  M.  rubra  Sm.,  but  my  specimen  has  the  leaves 
considerably  shrivelled  in  the  pressing.  It  has  no 
resemblance  to  either  gracilis  or  cardiaca _ C.E.S.  I  do 
not  know  Baker’s  cardiaca ;  but  Dr.  Long’s  specimen 
seems  to  be  the  plant  figured  in  “English  Botany,”  ed.  III., 
and  is  an  almost  entirely  glabrous  M.  arvensis  x  spicata. 
The  only  specimen  I  have  under  this  name,  from  Shotover, 
Oxon.,  1889  (G.  C.  Druce),  is  very  different ;  the  leaves 
are  sparsely  hairy  on  both  sides,  and  the  calyces  are  very 
pubescent.  This  I  regard  as  a  better  intermediate ;  the 
present  plant  looks  more  like  a  compound  of  M.  spicata 
with  M.  arvensis  x  spicata.  The  influence  of  M.  arvensis 
is  pretty  clear,  in  both  cases _ E.S.M.  We  have  studied 
the  effect  of  cultivation  on  plants  so  little  as  yet  that 
one  hardly  dares  to  suggest  a  name.  But  I  should  say 
not  M.  cardiaca,  which  is  a  much  more  slender  plant. 
Where  the  characters  of  M.  arvensis  are  I  am  quite 
unable  to  see _ A.B.
