Odontoglossum  Wilckeanum  var,  Rothschildlanum. 
Our  illustration  of  this  splendid  variety  shows  its  immense 
size— fully  4.}in  across.  The  ground  colour  is  creamy-white, 
shading  to  yellow  at  the  tips  of  the  sepals.  There  are  several 
reddish-brown  spots,  while  on  the  petals  this  colour  appears  in 
irregular  spots  and  blotches.  The  lip  has  a  broad,  whitish  apex, 
and  this  is  prettily  fringed.  It  received  a  First  C'lass  Certificate 
from  the  Orchid  Committee  when  exhibited  at  Westminster  on 
September  2,  by  Norman  Cookson,  Esq.,  (gardener,  Mr.  H.  J. 
Chapman),  Oakwood,  Wylam-on-Tyne.

D.  Famieri  is  another  very  pretty  evergreen  species  from 
Moulmein.  In  this  the  sepals  and  petals  are  yellow  with  a  rosy 
suffusion,  the  lip  deep 
yellow,  while  the  ra¬ 
cemes  are  looser  than 
those  of  D.  densi- 
florum.  D.fimbriatum 
and  its  variety  ocula- 
tum  are  tall-growing 
evergreen  species, 
bearing  loose  yellow 
flowered  racemes. 
They  are  natives  of 
the  Himalayas. 
D.  Findlay anum  is 
a  peculiarly  habited 
species,  the  joints 
much  swollen  at  the 
nodes  and  very  slen¬ 
der  below.  The 
flowers  are  whitish  or 
pale  lilac  in  ground 
colour,  the  lip  yellow 
with  a  whitish  mar¬ 
gin.  No  difficulty  will 
be  found  with  this 
pretty  deciduous 
species,  which  is 
named  after  a  Mr. 
James  Findlay,  who 
discovered  it  in  Bur- 
mah  in  1867.  D. 
formosum  is  perhaps 
the  best  known  of  the 
nigro  -  hirsute  group, 
and  a  very  beautiful 
Orchid.  The  pure 
white  flowers  are 
large  and  very  hand¬ 
some,  the  yellow  stain 
on  the  lip  serving  the 
better  to  show  the 
purity  of  the  other 
segments.  This  is  one 
of  the  many  fine 
Orchids  the  late  Mr. 
Gibson  sent  to  his  employer,  the  Duke  of  Devonshire,  at  Chats- 
worth,  he  having  found  it  on  the  Khasia  Hills.  But  it.  is  a  widely 
distributed  species,  and  plants  have  been  collected  over  a  very 
wide  area. 
Another  lovely  species  belonging  to  the  black  haired  section 
•is  D.  infundibulum.  This,  when  in  good  condition,  will  grow 
30in  in  length,  the  upper  foot  or  so  being  wreathed  with  the  beau¬ 
tiful  pure  white  flowers,  with  a  dense  yellow  eye  to  each.  Grow  this 
in  the  cool  end  of  the  Cattleya  house ;  in  the  warmest  house  it  is 
sure  to  be  attacked  by  tlirips.  Its  variety,  D.  Jamesianum,  has 
shorter,  stouter,  and  more  erect  stems,  the  flowers  being  slightly 
different  in  form.  A  cool  and  very  moist  atmosphere,  small  pans, 
and  abundant  supplies  of  air  and  root  moisture  are  necessary  for 
these  two  fine  plants.  D.  lituiflorum  is  worthy  of  a  place,  and 
makes  a  very  pretty  basket  plant,  its  pendulous  stems  being  in 
spring  covered  with  the  pretty  pink  and  white  flowers. 
D.  Lowi  is  an  uncommon  and  handsome  species  belonging  to 
the  same  set  as  D.  formosum,  and  bearing  light  buff  yellow  flowers 
stained  on  the  lip  with  red.  It  comes  from  Borneo,  and  was  dis¬ 
covered  and  sent  home  by  Mr.  Hugh  Low  some  forty  years  ago. 
D.  MacCarthise  is  a  very  beautiful  species,  but  with  a  very  un¬ 
enviable  reputation  among  growers.  In  colour  it  resembles  a 
good  form  of  1).  nobile,  the  flowers,  however,  seldom  opening 
quite  fully.  Probably  this  species  will  never  become  really  welL 
established  in  collections,  as  it  is  questionable  whether  the  plants 
are  very  long  lived,  even  in  their  native  habitat.  Treat  it  as 
advised  for  the  deciduous  group. 
D.  Macfarlanei  is  a  pure  white  flowering  species,  known  also  as 
D.  Johnsonise.  It  is  a  native  of  New  Guinea  and  other  parts  of 
Australasia,  and  has  of  late  been  much  more  plentiful  in  collec¬ 
tions  owing  to  importations  by  Messrs.  Sander  and  Co.  and  other 
firm;.  It  should  be  included  in  anv  representative  collection. 
D.  mosohatum,  and  its  variety  calceolaria,  is  a  very  strong  and 
stout  grower,  throwing  up  immense  stems  over  6ft  in  height,  that 
in  their  second  year  produce  loose  racemes  of  yellow  flowers  with 
deep  purple  or  maroon  blotches  on  the  lip.  These,  although 
making  a  grand  show,  only  last  a  week  or  ten  days,  and  owing  to 
the  bulk  of  the  plant,  it  is  unsuited  to  small  collections. 
The  well-known  D.  nobile  is  perhaps  the  finest  garden  Orchid 
in  existence.  Its  varieties  are  very  numerous,  and  it  thrives  in 
an  ordinary  stove  or  warm  greenhouse  as  well  as  in  the  Orchid 
house  proper.  It  has  been  used  with  great  success  as  a  parent  by 
hybridists,  and  is  quite  indispensable  to  every  collection.  Besides 
the  type,  the  finest  of  all  the  varieties  are  D.  n.  nobilius,  D.  n. 
Schroderianum,  the  beautiful  albino,  and  D.  n.  elegans.  By 
bringing  the  plants  on  in  succession,  its  flowering  season  may  be 
made  to  extend  for  six  months  or  more,  and  it  i.s  easily  propagated 
either  by  division  or 
by  laying  the  stems 
cn  pans  of  moss. 
D .  ochreatum  or 
Cambridgeanum,  as  it 
is  also  known,  has 
stems  8in  or  so'  in 
length,  and  it  flowers 
upon  these  in  a  green 
state  like  D.  chrys- 
anthum.  Its  blos¬ 
soms  are  a  bright 
yellow  with  a  deep 
stain  on  the  lip.  After 
flowering  it  should  be 
rested  in  a  cool  house 
and  repotted  or  top- 
dressed  when  it  com¬ 
mences  to  grow  in 
spring.  It  is  a  native 
of  India,  and  first 
flowered  in  this 
country  at  Chats- 
worth  in  1838.—

The  Week’s  Cultural 
Notes. 
In  many  small  col¬ 
lections  of  Orchids,  as 
well  as  in  the  large 
ones,  there  is  a  com¬ 
partment  devoted  to 
flowering  plants  alone. 
This  is  a  very  good 
idea,  as  the  blossoms 
last  far  longer  than 
when  the  plants  are 
kept  to  the  growing 
quarters.  Not  always, 
perhaps,  are  there 
Orchids  enough  in 
flower  to  furnish  it  properly,  and  other  plants  of  an  ornamental 
character  have  to  be  brought  in.  Flowering  plants  other  than 
Orchids  are  not  usually  to  be  recommended,  those  having  orna¬ 
mental  foliage  being  most  suitable,  as  nothing  in  the  whole  race 
of  flowering  plants  looks  really  well  in  conjunction  with  Orchids. 
Small,  well-coloured  pieces  of  Croton,  Caladium,  Coleus, 
Dracaena,  Fittonia,  Panicum,  and  Tradescantia  help  materially  in 
brightening  up  a  group  of  Orchids,  and  with  the  aid  of  these  and 
some  Ferns  of  various  sizes,  a  fewr  flowering  specimens  may  be 
made  to  go  a  long  way.  Anthurium  Scherzerianum  may  be 
admitted,  as  this  serves  to  make  a  contrast  with  the  usually  rather 
sombre  tints  of  the  Orchid,  and  it  is  very  lasting.  Small  Palms 
at  intervals,  and  larger  specimens  to  flank  and  back  up  the  group 
are  excellent,  and  the  whole  arrangement  must  bo  kept  as  light 
as  possible,  not  arranged  in  a  flat  sloping  bank,  but  with  distinct 
specimens  standing  out  here  and  there,  the  kinds  varying,  of 
course,  with  the  season. 
Just  now  the  deciduous  Calanthes  are  rapidly  approaching  the 
flowering  stage;  as  long  as  the  leaves  are  healthy  and  the  roots 
correspondingly  active,  continue  to  allow  the  usual  water  supply, 
but  as  these  die  off,  very  little  moisture  will  bo  needed,  and  aa 
soon  as  the  flowers  are  well  open  the  water  supply  may  as  well  be
