R.  rhombifolius  Weihe,  forma  umbrosa.  Tilford  and 
Hindhead  Road,  Churt,  Surrey,  v.c.  17,  Aug.  6  &  13,  1912. 
This  is  the  shade  form  referred  to  in  the  concluding 
paragraph  of  my  description  of  R.  rhombifolius  on  page  36 
of  “  Handbk.  Brit.  Rubi.”  Very  similar  as  this  form  is  in 
dried  specimens  to  some  states  of  R.  holerythros,  the 
growing  bushes  may  usually  be  distinguished  readily 
enough  by  their  arcuate-procumbent  or  climbing  stems, 
their  comparatively  narrow  and  more  sharply  toothed 
leaflets,  and  their  more  regular  panicle  leafy  above  with 
more  strongly  falcate  prickles  and  long  lower  branches 
rising  at  an  acute  angle.  The  flowers,  though  very  similar, 
are  also  smaller  and  the  sepals  conspicuously  reflexed, 
while  those  of  R.  holerythros  are  normally  patent  or 
ascending  after  the  fall  of  the  petals _ W.  Moyle  Rogers.

R.  lentiginosus  Lees.  (Ref.  No.  343).  Rocky  ground  at 
Capel  Curig,  among  low  bushes  on  the  ascent  to  Moel

A  beautiful  set  of  flowering  specimens  of  Lees’  type  from 
his  locality  (Aug.  1849),  as  shown  by  the  specimen  now  in

R.  [lasioclados  Focke] .  Bury  Camp,  Moorend,  W.  Glos., 
v.c.  34,  July  15,  1912 — Ida  M.  Roper.  Is  not  this  a 
leucostachys  form  ?  Mr.  Rogers  now  regards  lasioclados 
as  having  originated  from  crosses  between  R.  rusticanus 
and  R.  leucostachys.  I  do  not  see  any  sign  of  the  former 
in  Miss  Roper’s  specimen — E.S.M.  I  should  name  all  the
