Agrostis  alba  L.,  var.  coarctata  (Hoffrn.)  Spring-head, 
Pill,  N.  Somerset,  v.c.  6,  July  18,  1911.  This  seems  to 
agree  with  the  published  description _ Ida  M.  Roper.  I 
think  that  this  is  A.  coarctata  Hoffmann,  “  Flora  Ger¬ 
manise, ”  part  I.,  p.  37  (1800),  which  he  thus  described  : — 
“  panic,  divaricata  capillari  mutica,  catycibus,  subaequali- 
bus,  corollis  brevioribus  obtusis  hispidulis,  fol.  angustis.

by  Prof.  E.  Hackel  as  A.  alba,  var.  coarctata  (Hoffm.) _

Deschampsia  ccespitosa  Beauv.,  var.  pallida  Koch. 
Woods,  Rosslyn,  Edinburghsh.,  v.c.  83,  July  3,  1911 _ McT. 
Cowan,  jun.  The  oldest  name  for  this  appears  to  be  Aira 
ccespitosa  L.,  var.  argentea  Gray  (1825, 1  think)  =  ccespitosa, 
P  pallida  Koch  [1846] .  An  author’s  name  is  needed,  under 
Deschampsia.  Ascherson  and  Graebner  (“  Synopsis,”  II., 
part  1,  290)  refer  Koch’s  plant  to  their  form  2  altissima 
of  the  type  ;  but  they  describe  this  as  a  shade-form,  usually 
taller  (up  to  P5  metres);  panicle  with  more  numerous 
branchlets ;  glumes  yellowish  above — which  does  not  fit 
our  plant  at  all  well.  This  is  sometimes  small,  not  much 
over  a  foot  high,  with  silvery  flowers ;  often,  but  by  no 
means  always,  it  occurs  in  shade.  I  regard  it  as  an  albino, 
rather  than  a  real  variety — E.S.M.  There  is  some 
difficulty  in  assigning  the  correct  varietal  name  to  this
