but  during  the  reoent  revision  of  all  speoies  of  fungi,  by  Saocardo,  it 
has  been  called  Botrytis  canescens.  Whether  it  is  different  from 
Botrytis  elliptioa  I  cannot  say.  Another  species  of  Botrytis  has  been 
found  in  Britain  and  Holland,  on  leaves,  Btems,  and  flowers  of  cultivated 
Tulips.  It  is  called  Botrytis  parasitica  (‘Cavara  App.  Pat.  Veg.,’  10, 
tab.  vi.,  figs.  1  to  4).  This  is  probably  different  from  the  Botrytis  on 
Lilies,  although  it  is  not  improbable  that  it  might  develop  upon  Lilies  if 
it  came  in  contact  with  them.  Having  in  View  the  conference  which  is 
shortly  to  take  place,  it  may  be  interesting  to  allude  to  all  the  fungoid 
diseases  of  Lilies  which  have  come  under  my  notice  ;  and,  in  this 
connection,  it  is  satisfactory  to  learn  that  the  number  of  pests  is 
below  the  average  of  plants  so  largely  cultivated.  No  other 
parasitio  mould  has  been  recorded,  and,  only  recently,  one  species  of 
Mucor  which  attacks  Lily  bulbs  raised  in  Japan  for  exportation  to 
Europe.  This  speoies  is  Rhizopus  necans,  described  by  Massee  (“  Kew 
Bulletin,”  1897,  page  87,  with  plate),  and  attacks  the  bulbs,  which  soon 
by  incomplete  fungi,  called  the  Sphoeropsideae.  Here,  again,  the 
British  cultivator  may  congratulate  himself,  since  Phyllostiota  lilioola, 
■  m  the  leaves  of  Lilium  candidum,  has  not  extended  beyond  Italy  ;  and 
Phyllostiota  lilii  on  Lilium  superbum,  is  at  present  confined  to  Canada. 
There  is  an  allied  parasite,  with  some  technical  difference,  called 
Cylindrosporium  inconspiouum,  found  on  leaves  of  the  Hartagon  Lily, 
but  at  present  confined  to  Switzerland.  Altogether  this  report  should 
Hve  courage  to  the  English  cultivator  of  Lilies,  inasmuch  as  the  ‘  Lily 
Disease,’  so  called,  associated  with  Botrytis,  is  the  only  one  which  need 
cause  anxiety.”  Mr.  Wilks  observed  that  the  best  remedy  was  to  place 
the  diseased  Lily  bulbs  in  a  bag  of  sulphur  in  some  hot  place  in  a 
greenhouse;  then  to  replace  them  in  the  ground,  but  not  too  deeply.  A 
unanimous  vote  of  thanks  was  given  to  Dr.  Cooke  for  his  report  on  the 
fungus  sent  to  the  last  meeting,  as  well  as  on  the  present  occasion. 
Lily  hybrids. — Mr.  Bowles  exhibited  blossoms  of  L.  Dalhansoni,  the 
result  of  L.  dalmaticum  x  Hansoni,  to  show  the  difference  in  colouring.

become  rotten  and  exhibit  clusters  of  tiny  filaments  with  black  heads, 
like  miniature  pins.  These  heads  enclose  minute  conidia,  whilst  resting 
spores  or  zygospores  are  produced  within  the  tissues  of  the  decayed 
bulbs,  and  thus  perpetuate  the  speoies  after  a  period  of  rest.  The 
section  of  fungoid  parasites  which  include  the  smuts,  rusts,  and  brands 
is  represented,  although  there  is  no  smut  such  as  infests  Erythronium 
or  Ornithogalum.  The  cluster  cups  of  the  Lily  of  the  Valley  (iEoidium 
convallarite),  has  occurred  on  Lilium  canadense,  and  another  cluster 
cup  (.ZEcidium  SafiaDoffianum)  occurs  on  Martagon  Lilies  in  Siberia. 
Of  the  brands  with  simple  teleutospores  consisting  of  a  single  cell,  the 
most  common  is  Uromyces  Erythroni  on  Lilium  canadense,  in  Europe  ; 
and  another,  less  common,  probably  unknown  in  Europe,  is  Uromyces 
Lilii,  described  as  a  pest  of  Lilies  in  the  United  States.  To  these  must 
be  added  the  brands  with  two-celled  teleutospores,  although  I  am  not 
aware  that  Puocinia  liliacearum,  notwithstanding  its  name,  has  been 
found  to  attack  Lilies,  although  it  is  known  in  Britain  on  Gagea  and 
Ornithogalum.  Two  other  species,  Puccinia  Tulipse  and  Puocinia 
fallaciosa,  attack  Tulips,  so  that  on  the  whole,  the  Lilies  are  favoured 
by  almost  immunity  from  these  forms  of  fungoid  pests.  The  last  group 
or  seotion  of  parasites  to  which  I  need  allude  are  the  leaf-spots  caused 
Hybrid  Passion  Flowers. — Dr.  Masters  undertook  to  report  on  some 
examples  received  from  Dr.  J.  H.  Wilson,  St.  Andrews. 
Tuberose  diseased. — He  also  brought  some  specimens  received  from 
Mr.  C.  Maers,  Hockley,  Essex,  upon  which  Dr.  Cooke  reports  as 
follows  : — “  In  the  decayed  crown  of  the  corm  I  find  no  mycelium,  or 
evidence  that  the  decay  was  caused  in  the  first  instance  by  fungi ; 
but  plenty  of  inseots  were  present.”  Dr.  Masters  observed  that  such 
decay  was  usually  at  the  base,  not  the  apex,  of  the  oorm,  as  in  the 
present  instanoe. 
Carnations  diseased. — Mr.  G.  Roberts  of  Exton  Park  sent  some 
plants  which  were  in  a  failing  condition.  Dr.  Cooke  examined  them, 
and  reports  as  follows  : — “  The  Carnations  evidently  suffered  in  the  first 
instance  from  worm  at  the  roots ;  afterwards,  when  the  foliage  was 
failing,  they  beoame  attacked  by  the  Carnation  mould  (Heterosporium 
echinulatum,  figured  in  ‘  Gard.  Chron.,’  August  21st,  1886,  fig.  50).  It 
is  doubtful  whether  these  particular  black  moulds  will  attack  healthy 
and  vigorous  plants  ;  but  when  they  are  weak,  sickly,  or  injured,  they 
then  become  a  ready  prey.” 
Apple-stems  attacked  by  caterpillars. — Specimens  were  sent  by  Mr. 
W.  Camm  of  Abbey  Gardens,  Battle,  Sussex,  upon  which  Mr.  Saunders
