lady’s  is  said  to  be.  Mr.  Piper  ia  big  note  says  G^ndral  Jacqueminot  is 
the  oldest  H.P.,  but  not  as  “A.  D.”  seems  to  think,  in  existence.  I  ] 
fancy  Mr.  Piper  simply  alluded  to  age  in  Mr.  Mawley’s  analysis.  I  i 
am,  however,  disposed  to  think  that  Mr.  Piper  is  in  error  as  to  the  age  of  j 
the  old  Q(in4ral,  any  way  the  most  comprehensive  list  of  Eoses  I  have 
ever  seen  is  contained  in  “  The  Eose,”  by  H.  B.  Ellwanger,  Eochester,  j 
N.Y.  Mr.  Ellwanger  was  (I  am  truly  sorry  to  write  war,  but  he  bar 
joined  the  majority)  devoted  to  Eose  growing,  and  was  most  kind  to  my¬ 
self  when  in  former  days  I  had  to  do  with  the  Eose  elections,  the  only  bond 
between  ns  being  our  mutual  love  for  the  Eose,  and  kindly  wrote  me , 
filling  up  blanks  here  and  there  in  the  lists,  and  when  he  brought  on  t 
his  book  most  kindly  forwarded  me  a  copy,  which  1  greatly  value.  If 
concludes  with  a  list  of  no  less  than  956  Eoses,  most  of  which  have  the 
date  of  introduction  and  the  raiser’s  name. 
In  this  catalogue  the  H.P.’s  are  called  Eemontant,  and  many  of 
DRAC^NA  BROOMFIELDI; 
Amokgbt  the  many  handsome  Dracaenas  that  are  found  of  such 
great  value  must  now  be  placed  a  new  Australian  species  named 
D,  Broomfieldi,  as  it  is  undoubtedly  of  the  highest  merit,  It  was 
exhibited  at  the  Drill  Hall  on  the  occasion  of  the  last  meeting  of  the 
Committees  of  the  Eoyal  Horticultural  Society,  attracting  the  greatest 
attention  and  receiving  a  first-class  certificate.  A  glance  at  the  woodcut 
(fig.  93)  will  show  the  habit  of  growth,  which  is  very  short-jointed, 
and  also  the  elegance  of  the  leaves,  which  measure  about  2  feet  in 
length  and  2  inches  in  width  when  at  their  greatest  size.  The  centre 
of  each  leaf  is  rich  glossy  green,  occasionally  striped  with  white,  the 
margins,  upwards  of  a  quarter  of  an  inch  in  width,  being  pure  white,

the  Eoses  most  of  us  have  never  grown,  and  possibly  have  never  heard  of. 
I  give  a  list  of  the  oldest  H.R.’s,  or,  as  we  call  them,  H.P.’s,  I  can 
find  : — 
Madame  Zaffay  (Laffay,  1839). — Eose  colour. 
“  Rivtrs'  ”  Laffay  (1839).— Eose  colour. 
, IS  of  Sutherland  (Laffay,  1840). — Eosy  pink. 
WiUia7n.  Jtsse  (Laffay,  1840). — Eed,  suffused  violet. 
Baronue  Provost  (Desprez,  sent  out  by  Cochet  in  1842). — Pure  rose. 
La  Reine  (Laffay,  1843). — Glossy  rose. 
Yolande  d'  Aragon  (Vibert,  1843). — Lilac  rose. 
Alphonse  Karr  (Portemer,  1846). — Flesh  colour,  margined  carmine. 
GmiU  des  BataUles  (N^rard,  1846,  sent  out  by  Gnillot,  pere). — 
Fiery  red. 
Jaques  Lahtte  (Vibert,  1846). — Eosy  crimson. 
Sydonie  (Dorissy,  1846). — Eose  colour. 
From  these  extracts  it  would  appear  that  the  early  H.P.’s,  although 
they  were  the  forerunners  of  the  lovely  forms  of  to-day,  did  not  give 
great  promise,  and  the  rosarians  and  hybridisers  of  the  past  fifty  years 
have  vastly  improved  the  forms  of  the  queen  of  flowers.  Further,  it 
would  seem  that  the  pioneer  of  the  H.P.’s  was  Laffay.— Y.  B.  A.  Z. 
thus  giving  the  plant  a  very  striking  appearance,  more  after  the  style  of 
a  Pandanus  than  a  Dracaena.  The  plant  will,  we  understand,  require 
stove  treatment  for  its  successful  culture.  Messrs.  F.  Sander  &  Co., 
St.  Albans,  were  the  exhibitors.

The  Recent  Bijfferentiaiion  of  the  Wheat  MUdeWS. — The  following 
interesting  communication  was  received  from  Dr.  Plowright. 
On  the  Recert  Differentiation  of  the  Wheat  Mildetos, — We  are  all 
familiar  with  what  is  known  to  us  in  Great  Britain  as  the  Wheat 
Mildew  par  excellence,  Puccinia  graminis.  Curiously  enough  during  the 
past  season  (1896)  it  has  been  practicaUy  absent  from  our  cornfields. 
The  only  specimens  I  have  seen  have  been  upon  Triticum  repens,  and 
on  Barley.  These  were  only  found  after  careful  searching  in  the  imme-
