Phalaenopsis  Manni. 
Mr.  H.  R.  Richards  interestingly  referred  to  this  bright  and  pretty 
species’on  page  73  of  last  week’s  issue,  and  the  accompanying  illus¬ 
tration  bears  out  his  remarks  as  made.  Growers  lacking  this  species 
might  be  induced  to  give  it  a  trial. 
now  be  well  watered  and  kept  in  a  strong  moist  heat,  with  their 
heads  well  up  to  the  light. 
Odontoglossums  are  rather  erratic  in  their  habits  of  growth,  and 
some  plants  are  sure  to  be  more  forward  than  others.  When  it  is 
evident  that  the  young  shoots  are  sufficiently  forward — i.e.,  when 
roots  are  about  to  be  produced,  they  may  be  given  new  material, 
but  nothing  like  a  general  potting  must  take  place  before  the  end  ot 
August  or  September.  Any  plants  that  are  repotted  should  be  stood 
by  themselves  in  the  coolest  and  moistest  part  of  the  house,  and  given 
heavy  shading  until  they  recover.  Although  the  roots  need  keeping 
a  little  drier  after  repotting,  water  must  be  more  frequently  applied, 
the  apparent  paradox  being  explained  by  the  fact  that  the  new 
compost  dries  far  more  rapidly  than  the  old. 
Few  people  nowadays  grow  the  beautiful  large  growing  Yandas,

The  Week’*  Cultural  Notes. 
In  the  warm  house  Calanthes  will  now  be  growing  very  freely,  and 
the  pseudo-bulbs  will  be  forming.  Now,  if  ever,  is  the  time  when 
feeding  at  the  roots  with  liquid  manure  should  be  practised ;  but  it  is 
«aBy  to  overdo  this  kind  of  thing  with  Orchids,  and  I  have  yet  to 
learn  that  a  large  plethoric  bulb  produces  finer  flowers,  or  more  of 
them,  than  a  medium  sized  well-developed  one.  Only  when  the  plants 
are  growing  in  small  pots  or  a  poor  soil  should  they  need  feeding,  and 
the  manure  water  used  should  be  weak,  and  at  the  same  temperature 
as  that  of  the  house.  Catasetums,  Cycnoches,  and  Mormodes  should 
Aerides,  and  others  of  a  like  habit  that  used  to  be  so  popular.  Those 
who  do  should  be  careful  not  to  keep  them  too  hot  at  this  season,  and 
to  see  that  the  temperature  is  well  balanced  by  air  and  moisture.  They 
like  roomy  quarters,  and  are  seldom  satbfactory  in  small  houses  with 
their  heads  against  the  glass.  Vanda  suavis,  V.  tricolor,  and  its 
varieties  are  quite  comfortable"  now  in  the  Cattleya  house,  and  the 
atmosphere  here  is  quite  congenial  to  them. 
The  weather  of  the  last  few  days  shows  how  necessary  it  is  to 
always  have  the  fires  laid  ready  even  in  summer.  A  drop  of  over  20°  in 
the  outside  temperature  in  ahout  as  many  hours  is  bound  to  be  felt  by 
such  sensitive  subjects  as  Orchids,  and  unless  a  little  warmth  is  at
