to  easily  estiblish.  Tnree  or  four  forms  of  L.  candidum  must  not  be 
omitted.  The  better  these  are  tilled  and  cared  for  the  more  free  they 
keepYrom  the  devastating  fungus  now  so  common  in  this  species, 
brought  about  mainly  from  uncleanliness.  L.  lougiflorum,  the  type, 
can  also  be  successfully  established  in  ordinary  soil,  but  can  be 
improved  if  slightly  protected  when  the  young  growths  appear, 
which  is  usually  very  early  in  the  spring.  L.  japonicum  Browni  I 
have  also  succeeded  in 
.  growing  in  open  beds  with¬ 
out  protection  of  any  kind, 
and  in  ordinary  garden  soil. 
It  is  a  very  handsome, 
choice,  bold  looking  Lily. 
The  yellow  L.  Szivitzi- 
anum  is  also  an  easy  plant 
to  establish,  and  where 
shade  is  afforded  by  other 
plants  it  reaches  4  feet, 
an  1  has  a  very  graceful, 
and  even  noble  appearance

Irises. 
Spanish  and  English 
Irises  are  here  represented. 
The  earliest  of  the  Iris 
family  to  open  out  upon  a 
cold  and  comfortless  world 
are  the  Iris  reticulata 
varieties,  and  Iris  persica, 
I.  Heldreichi,  pumila,  and 
orchioides.  These  are  not 
long  past  before  the  bold 
and  handsome  German 
Irises  come  in  substitution, 
and  even  while  these  are 
in  flower  the  Spanish  and 
the  English  rivals  are  bril¬ 
liant  everywhere.  These 
“poor  man’s  Orchids” 
delight  in  a  sunny  soil, 
light  and  free  if  possible, 
but  the  aspect  must  be 
sunny  if  the  greatest 
success  is  to  be  secured. 
We  think  their  culture 
ought  to  be  much  more 
extended  ;  we  want  to  see 
them  in  as  great  luxuri¬ 
ance  as  are  some  of 
the  Daffodils  in  spring. 
Where  they  have  not 
been  tried  (though  we  can 
scarcely  imagine  a  garden 
without  them),  perhaps  a 
selection  can  be  chosen 
for  this  autumn’s  planting. 
Some  of  the  best  varieties 
noted  in  such  collections 
as  Messrs.  J.  Yeitch  and 
Sons’,  for  instance,  shown 
at  metropolitan  exhibi¬ 
tions,  are  Chrysolora,  Jupi¬ 
ter,  Mont  Blanc,  Canary 
Bird,  and  Garibaldi  in 
the  Spanish  section,  and 
•Charles  Dickens,  Harle¬ 
quin,  La  Grandesse,  Prince 
Imperial,  Cleopatra,  &c., 
amongst  English  Irises.  The  illustration  of  Messrs.  Yeitch  shows 
a  truss  of  Irises,  reduced.

End  of  a  Giant  Oak. — “  Thwaite’s  Oak,”  the  finest  in  Norfolk, 
"measuring  over  21  feet  in  circumference,  was  sold  at  Tivetshall, 
Norfolk,  last  week.  The  trunk  is  about  19  feet  long,  and  alone  fetched 
:£4L  Many  of  tie  principal  arms  were  as  large  as  a  big  tree.  The 
amount  produced  by  the  whole  tree  was  £72,  exclusive  of  some  £20 
previously  obtainrf  by  the  sale  of  bark,  chips,  &c. 
Suckers. — Those  reoently  started  should  be  raised  near  the  glass 
as  soon  as  the  roots  are  plentifully  made,  so  as  to  secure  a  sturdy 
thoroughly  solidified  growth,  especially  in  plants  to  be  wintered  in 
small  pots.  When  the  suckers  become  well  rooted  transfer  the 
strongest,  started  late  in 
summer,  to  the  fruiting 
pots  at  once,  draining  these 
well.  Employ  the  fibrous 
pare  only  of  sound  turfy 
loam,  in  lumps  proportioned 
to  the  size  of  the  pots. 
Jamaicas  are  apt  to  become 
weak  and  attenuated  in 
growth  when  grown  in 
large  pots ;  9  or  10-inch 
pots  suffice  for  them,  and 
they  must  not  be  grown 
away  from  the  glass,  or  be 
kept  very  moist  and  close. 
Queens  succeed  in  10-inch 
pots,  or  very  strong  plants 
may  be  given  a  little  more 
root  space,  say  11-inch  pots. 
Envilles  have  all  their  re¬ 
quirements  ae  regards  soil 
supplied  in  10-inch  pots. 
Smooth-leaved  Cayennes 
ancoeed  in  10  -  inch  pots, 
11-inch  at  most ;  and  Pro¬ 
vidence  in  11  or  12-inch 
pots.  Tne  small  plants 
should  be  shifted  into  7  or 
8-inch  pots,  in  which  they 
must  be  kept  until  spring. 
Plunge  the  pots  in  a  bottom 
heat  of  90°  to  95°,  in  which 
they  must  be  continued 
until  /he  roots  have  taken 
freely  to  the  fresh  compost, 
when  they  may  be  raised, 
a  temperature  of  185°  being 
afterwards  sufficient. 
Growing  Stock. — Young 
plants  require  free  ventila¬ 
tion  on  all  favourable  occa¬ 
sions  to  keep  them  in  a 
healthy  sturdy  condition, 
maintaining  a  night  tem- 
oerature  of  60°  to  65°,  with 
5°  to  10°  more  by  day  arti¬ 
ficially  unless  dull  and  cold, 
and  keep  at  80°  to  85°  from 
sun  heat.  Ventilate  early 
in  the  day,  so  as  not  to 
lower  the  temperature, keep¬ 
ing  the  bottom  heat  steady 
at  80°.  Water  the  plants 
whenever  they  require  it, 
employing  weak  and  tepid 
liquid  manure.  Avoid  the 
use  of  the  syringe  too  fre¬ 
quently,  as  sprinkling  the 
plants  has  a  weakening 
effect ;  suffice  to  damp  the 
paths  in  the  morning  and 
afternoon  in  all  but  very 
bright  weather.  Fruiting 
plants  should  have  a  night 
temperature  of  70°,  with 
S0°  to  90°  by  day,  closing 
at  85°.— Practice. 
ENGLISH  AND  SPANISH  IRISES. 
Dlchorisandra  thyrsl- 
llora. — Seldom, now-a-day  s, 
do  we  rejoioe  in  the  sight 
of  this  handsome  Brazilian  perennial  with  its  thyrsus  of  rich,  dark  blue 
flowers,  whose  yellow  anthers  contrast  so  pleasing.  D.  thyrsi il ora  is 
surely  the  prettiest  species  in  the  genus.  As  a  stove  plant  it  surpasses 
in  decorative  value  many  of  more  recent  introduction,  that  entail 
considerably  more  care  and  attention  to  obtain  them  in  good  condition. 
The  flowers  are  generally  thrown  up  profusely,  and  certainly  the  plant 
is  a  speedy  grower.  The  inflorescences  are  compact,  and  frequently  six 
or  seven  inohes  in  length,  the  sheathing  leaves  being  broad  and  of  a  dark 
green  colour.  There  is  no  absolute  need  to  oonfine  the  plant  to  strict 
stove  treatment ;  during  summer  an  unheated  conservatory  will  do.
