At  tlie  meeting  of  the  Royal  Horticultural  Society,  held  in 
the  Drill  Hall,  Westminster,  on  Februai’y  25,  both  Messr.s,  Hugh 
Lou'  and  Co.,  Enfield,  Middlesex,  and  Messrs.  Sander  and  Sons, 
St.  Albans,  exhibited  this  nei.v  hybrid,  each  receiving  an  Award 
of  Merit.  'Phe  flowers  are  of  graceful  form,  the  petals  and  sepals 
being  wavy.  The  lip  is  long,  fluted,  and  bent  down  in  front,  the 
edges  being  much  crinkled  and  coloured  bright  rose-purple,  with 
a  yellow  disc  and  some  dark  lines  on  cither  side.  The  petals  and 
sepals  are  more  lightly  coloured  than  the  lip.  The  parents  were 
Laelia  superbiens  x  ('attleya  Mossiae.

Moorea  irrorata. 
The  Kew  ])lant  cf  this  vei^^  handsome  Orchid  (of  which  only 
I  two  plants  are  in  cultivation,  we  believe)  is  developing  t-wo  stout 
j  racr^mes  of  its  chestnut-coloured  flowers.  The  inflorescences  are 
not  so  sti'ong  as  those  thrown  up  last  season.  A  figure  of  this 
!  Orchid  (named  in  honour  of  Mr.  F.  W.  Moore,  curator  of 
Glasnevin  Botanic  Gai'dens)  was  given  in  the  Journal  of  Hnrti- 
cultnrn,  April  4,  1901,  j  age  277. 
Cypripedium  Edmund  Rothwell. 
This  is  a  new  and  handsome  Cypripedium,  which  was  recently 
figured  in  “American  Gardening.”  The  photograph  also  shows 
As  soon  as  the  flowers  of  Coelogyne 
cristata  are  past  the  plants  commence  to 
form  new'  growths  and  roots,  and  this  is 
the  proper  time  for  rearranging  the 
compo.st.  'i'here  is  a  considerable  dif¬ 
ference  ill  the  habit  of  the  varieties  of 
this  useful  Orchid,  some  of  them  growv 
ing  very  compactly  with  the  pseudo¬ 
bulbs  close  together  upon  the  rhizomes, 
others  having  the  former  very  much 
farther  apart.  The  latter  claSs  of  plant 
gets  untidy  in  aiipearauce  much  more 
quickly  than  the'  former,  and  should 
have  a  little  new  compost  added  annually. 
.^s  this  is  placed  in  po.sition  the 
rhizomes  must  be  lifted  and  the  peat  and 
moss  carefully  dibbled  in.  An  endeavour 
should  be  made  toi  pull  the  leading 
growths  as  near  the  centre  as  possible, 
forming  a  well-filled  up  and  evenly 
balanced  plant.  Should  souring  of  the 
old  material  be  noticed  remove  the 
whole  of  it,  if  necessary  turning  the 
plants  out  of  the  pots  to  do  so,  but  not 
otherwise,  as  this  Orchid  dislikes  being 
pulled  about  at  the  roots.  Large  old 
specimens  may  need  a  ferv  of  the  back 
bulbs  removed,  but  this  is  not  advisable 
in  the  case  of  weak  or  small  plants.  A 
third  of  good  leaf  mould  added  to  the 
compost  is  an  advantage  for  this  plant. 
Just  now  there  is  a  great  disposition 
on  the  part  of  amateur  growers  to  over¬ 
water  plants  that  are  commencing  to 
grow.  Wait  until  both  roots  and  groAvth 
are  thoroughly  active  before  increasing 
the  Avater  supply,  or  the  compost  AA'ill  be 
soddened  before  the  neAv  roots  reach  it. 
A  moist  atmosphere  and  comparatively 
dry  condition  of  the  roots  is  much  better 
than  the  opposite  for  all  classes  of 
Orchids  noAV,  especially  the  deciduous 
sorts. 
Shading  has  not  yet  been  needed,  but  all  blinds  should  be 
got  ready  for  use,  as  bright  bursts  of  sunshine  after  a  rather 
exceptionally  dull  period  will  play  havoc  Avith  the  floAvers  of 
delicate  sorts.  A  very  light  shade,  and  for  a  short  time  only,  is 
reciuired  at  first  :  AA'eakly,  attenuated  groAvths  and  feAV  flowers 
folloAV  heavy  shading  early  in  the  year.  All  arrears  of  Avinter 
cleaning  must  be  brought  up  to  date,  as  a  plant  Avith  a  feAv  insects 
upon  it  Avill  soon  become  overrun  if  neglected.  Masdevallias  are 
notoriously  addicted  to  attacks  of  thrips,  especially  the  yellov 
variety,  which  spoils  the  beauty  of  the  floAvers.  Here  a  fcAA*  light 
fumigations  should  be  given,  using  one  of  the  excellent  A-apour- 
ising  compounds  advertised  in  the  Journal. — H.  R.  R.

“B.  M.”  t.  7,807. — Orchidace«e.  S.  The  specific  name  is  in 
allusion  to  the  resemblance  which  the  leafing  stem  bears  to  the 
the  two  parents  of  the  hybrid,  which  is  a  cross  between  Sallieri 
Hyeanum  and  Hookerse.  This  cross  was  made  January  5,  1896, 
and  the  seed  was  sown  January  27,  1897,  the  first  seedlings 
appearing  on  October  10  of  the  same  year.  The  first  floAver 
was  opened  on  January  3  of  the  present  year,  almost  exactly  six 
years  from  the  time  the  cross  Avas  made.  Description  of  the 
flower  is  as  follows  :  Dorsal  sepal^  primrose  yellow,  darkest  to¬ 
wards  the  base,  with  a  white  margin.  Petals,  rich  butter  yellow, 
with  a  strong  suffusion  of  the  purple  of  the  pollen  parent, 
Hookerse,  over  the  lower  half,  most  intense  at  the  extreme  ends. 
Inferior  sepal,  greenish,  much  the  shape  of  Hookerse.  The 
staminode  strongly  resembles  the  seed  parent,  Sallieri,  a  strong 
yellow  in  colour.  The  pouch  also  resembles  the  seed  parent  in 
shape,  and  is  a  dark  yellow  suffused  Avith  a  tawny  colour.  The 
spots  of  Sallieri  have  entirely  disappeared  from  the  dorsal,  and 
the  general  appearance  of  tlie  flower  is  a  decided  improvement 
over  those  of  the  parents,  and  yet  is  quite  intermediate.  The 
plant  from  which  this  is  bloomed  is  very  small,  and  a  decidedly 
larger  flower  is  expected  from  the  next  growth.  The  foliage  is 
almost  exactly  intermediate  in  colouring  and  appearance,  being 
beautifully  tessellated  like  that  of  Hookerse,  although  a  much 
lighter  colour,  and  Avith  the  upright  habit  of  Sallieri. — •
