OdontogloBBum  luteo-purpurenm  Mossi. 
There  are  now  numerous  varieties  of  the  handsome  Odontoglossum 
luteo-purpureum  in  cultivation,  and  Mr.  de  Barri  Crawshay,  Rosefield, 
Sevenoaks,  has  provided  still  another,  and  it  has  been  named  0.  l.-p, 
Mossi.  This  is  represented  in  the  illustration  (fig.  96),  in  which  the 
strikingly  handsome  form  of  this  variety  can  be  readily  seen.  The 
sepals  and  petals  are  yellow,  but  this  colour  is  almost  wholly  obscured 
at  the  base  by  brown,  and  the  whole  shines  as  if  with  a  coat  of  varnish. 
The  lip  is  very  beautiful.  The  chastely  fimbriated  front  portion  is 
pure  white  with  reddish  brown  at  the  base.  The  Orchid  Committee 
of  the  Royal  Horticultural  Society  at  the  meeting  held  in  the  Drill 
Hall  on  Tuesday,  April  10th,  recommended  to  0.  luteo-purpureum  an 
award  of  merit. 
Cypripedium  bellatulnm  album. 
The  typical  Cypripedium  bellatulum,  that  is  so  well  known  an(i 
so  highly  ai)preciated  by  Orchid  growers,  is  fortunately  abundant, 
and  with  reasonable  care  thrives  well  in  most  places.  The  white 
C.  bellatulum  album  (fig.  97)  is  much  choicer  and  rarer,  and  we  are  not 
surprised  that  a  correspondent,  signing  himself  “An  Amateur  Orchid 
Grower,”  has  not  met  with  it.  Examples  have  nevertheless  been 
exhibited  occasionally  at  the  meetings  of  the  Royal  Horticultural 
Society,  where  it  was  first  shown  by  Mr.  W.  H.  Young  on  June  11th, 
1895.  The  flower  is,  as  may  be  seen  in  the  engraving,  of  perfect  form, 
while  the  colour  is  pure  white.  On  the  occasion  of  its  initial  appear¬ 
ance  at  the  Drill  Hall  it  was  accorded  a  first-class  certificate  by  the 
unanimous  vote  of  the  Orchid  Committee.  It  is  described  in  the 
Journal  of  the  Royal  Horticultural  Society  as  “a  pure  white 
unspotted  form  of  great  beauty.” 
Cypripedium  bellatulum. 
Excepting  under  very  favourable  circumstances  I  doubt  whether 
this  Orchid  could  be  grown  in  a  cool  greenhouse.  It  is  not  so  much 
a  matter  of  temperature,  as  congenial  atmospherical  surroundings, 
which,  for  Orchids,  can  seldom  be  obtained  in  ordinary  greenhouses. 
However,  as  this  attractive  species  is  not  an  expensive  one  to  buy,  an 
attempt,  even  if  it  resulted  in  failure,  would  not  cost  much.  Estab¬ 
lished  plants  should,  in  this  case,  be  suspended  in  a  position  where  the

greatest  amount  of  moisture  is  secured,  and  where  the  air  is  fresh  and 
pure  but  not  <lraughty.  In  a  structure  of  this  class  shading  would 
hardly  be  necessary.  Wat^r  shoul  1  be  given  by  immersing  the  pots 
or  pans  to  their  rims  in  t-  pid  rain  water,  so  that  all  chance  of  ^y  lodging 
in  the^axils  of  the  leaves  is  remaved.  A  simple  way^to  tell  whether 
the  plants  require  water  or  not  is  to  gently  bend  a  leaf,  and  if  the 
action  cause  wrinkles  more  water  is  needed,  but  if  stiff  and  rigid, 
sufficient  moisture  is  present  in  the  soil.  Leas  harm  will  follovy 
dryness  at  the  root  than  prolonged  saturation. — W.  II.  Young. 
Dendrobium  Bulleriannm. 
This  very  pretty  Dendrobium  has  never  been  common  in  collec¬ 
tions,  and  is  now  seldom  seen,  yet  it  is  one  of  the  best  of  the  showy 
flowered  deciduous  species?,  not  unlike  D.  Devonianum,  but  rather 
stouter  in  growth.  The  flowers  appear  in  the  usual  manner  of  its 
class  along  the  last  year’s  stems,  and  are  about  a  couple  of  inches 
across,  with  rosy  purple  tips  to  the  whitish  sepals  and  a  large  yellow 
disc  to  the  lip.  It  likes  an  ample  moisture  supply  when  growing, 
especially  in  the  atmosphere,  and  may  he  kept  quite  dry  while  at  rest 
in  winter. 
Mormodes  luxatum. 
I  recently  noted  some  very  fine  spikes  of  this  Orchid,  a  plant  that 
some  may  think  more  curious  than  beautiful.  I  consider  it  one  of  the 
best  in  the  genus,  but  it  is  not  often,  I  think,  seen  in  flower  so  early. 
This  may  be  accounted  for  by  the  fact  lhat  the  plants  have  been  kept 
in  heat  all  the  winter,  not  the  wisest  of  proceedings  according  to  my

experience  of  it.  I  have  found  it  do  well  when  wintered  on  the  dry 
side  in  the  Cattleya  house,  exposed  as  much  as  possible  to  the  sun  and 
allowed  plenty  of  air. 
In  early  spring  more  heat  ought  to  be  allowed,  and  the  change 
should  be  rather  quickly  brouuht  about,  this  being  cmducive  to  free 
flowering.  The  plants  should  remain  in  heat  until  the  growth — and 
the  spikes  if  any  appear — are  progres.sing  fre.ly,  and  finished  with 
ample  sunlight  in  a  more  airy  if  not  a  c  aoler  house.  Although  the 
flowers  last  a  little  longer  in  a  cool  dry  house,  it  is  not  wise  to  keep 
them  out  of  their  growing  quarters  too  long,  as  t  e  young  leads  are 
apt  to  be  checked,  and  this  may  prevent  their  flowering  the  succeeding 
season.  In  colour  the  blossoms  vary  considerably,  the  type  having 
yellowish  flowers,  slightly  rose  red,  with  reddish  brown.  The  creamy 
white  variety  eburneum  and  the  spotted  punctatum  are  both  charmiug 
forms. 
Odontoglossum  Mulus. 
The  origin  of  this  species  or  variety  has  always  been  doubtful, 
many  considering  it  a  hybrid  between  0.  luteo-purpureum  and 
0.  gloriosum.  It  has  always  struck  me  as  having  a  little  of  0.  Halli 
in  it,  but  wliatever  its  origin,  it  is  a  tine  garden  Orchid — free  flower¬ 
ing  and  very  handsome.  I  have  known  it  to  produce  branching 
spikes  with  flowers  laiger  than  the  majority  of  0.  luteo-purpureum, 
and  the  blotches  are  in  some  cases  clean  cut  and  bold,  like  those  of 
0.  Wilckeanum.  It  is  easily  grown,  thriving  well  in  a  cool  house 
under  the  conditions  usually  allowed  for  0.  crispum. — H.  R.  R.  ,
