Caltha palustris  L.,  var.  Gueva?igerii  (Bor.).  Botlands, 
Chew  Magna,  N.  Somerset,  v.c.  6,  April  15,  1913. — Ida  M. 
Roper.  Doubtful,  on  the  material  received  ;  carpels  not 
developed.  The  sepals  are  rather  narrow  and  distant. 
This  station  is  accepted  in  the  “  Bristol  Flora.” — E.S.M. 
Erophila.  (See  also  Appendices). 
The  difficulty  of  dealing  with  the  segregates  of  this 
rather  fascinating  little  plant  is  enhanced  by  the  fact 
that  it  is  seldom  possible  in  a  natural  state  to  make 
a  pure  gathering.  I  sent  a  number  of  gatherings  to 
Mr.  Marshall  at  the  end  of  1912,  but  most  of  them  proved 
to  be  mixed,  and  therefore,  with  one  exception,  I  have  not 
made  use  of  his  determinations.  I  have  tried,  as  far  as 
may  be,  to  avoid  mixture  in  the  forms  now  distributed, 
but  will  not  venture  to  think  I  have  altogether  succeeded. 
Mr.  J.  A.  Wheldon,  on  whose  naming  I  rely  for  several  sets, 
says  that  on  the  whole  the  plants  I  submitted  to  him  are 
similar  to  those  which  he  finds  in  Lancashire.  The  hairs 
on  the  leaves  are  most  conspicuously  different  from  the 
other  sets  in  the  plant  which  he  refers  to  E.  spat  hula folia 
Jord.,  of  which  I  was  only  able  to  obtain  a  few,  being 
obliged  on  examination  with  a  lens  to  separate  these  from 
others  intermixed  which  I  had  at  first  believed  to  be 
homogeneous  with  them.  I  have  sent  seed  of  E.  stenocarpa 
Jord.  from  St.  Ippolyts  (Ref.  No.  60)  to  Dr.  Moss  to  be 
tested  under  cultivation. — J.  E.  Little.  Many  of  Jordan’s 
forms  are  too  near  each  other,  and  probably  half  a  dozen 
or  less  names  would  suffice  to  represent  the  actual 
“  micro  ”  species,  the  remainder  being  more  or  less  impure 
crosses.  Mentha  has  been  an  object  lesson  in  this  respect, 
but  of  course  in  Erophila  the  conditions  are  different,  as 
there  is  no  vegetative  reproduction  to  maintain  the  supply 
of  hybrids,  as  in  Willows  and  Mints. — J.A.W.

Pods  rather  short  and  broad ;  but  I  should  leave  this

few),  bifid  (chiefly,),  trifid  or  aggregate  (occasionally). 
Much  variation  in  the  silicles.  Perhaps  they  may  be
