O.  latifolia  is  very  abundant,  large  patches  sometimes  occurring. 
Listera  ovata  (Twayblade)  and  Ophioglossum  vnlgatum  also  occur  in 
a  ‘  dancing  bog,’  and  grow  very  large.  I  also  send  an  albino  Pedicularis 
palustris.” 
Tomatoes  attacked  by  fungus. —  Mr.  G.  E.  Day  sent  specimens 
diseased  with  Macrosporium  Lycopersioi.  It  was  in  the  young  state. 
The  best  remedy  is  spraying  with  Bordeaux  mixture. 
Asplenium  trichomanes ,  var. — Mr.  Druery  showed  a  plant  of  this 
Fern,  which  had  several  fronds  partially  bipinnate.  It  was  found  in 
Wales.  It  was  interesting  as  exemplifying  an  attempt  of  a  normally 
pinnate  species  to  assume  the  form  of  an  exotic  one.  The  variety  so 
far  did  not  approach  the  incised  section,  which  varies  on  quite  different 
lines. 
Papaver  Rh&as,  var. — Mr.  Druery  also  showed  flowers  of  a  Poppy 
having  an  intense  crimson  colour,  a  native  of  Asia  Minor.  They  were 
raised  from  seed  brought  from  Smyrna,  and  have  been  growing 
spontaneously  in  a  garden  for  two  years  at  Acton.  Eaoh  petal  had  a 
small  black  spot  or  line  at  the  base. 
or  asci,  each  containing  eight  sausage-shaped  sporidia  (16  - 18  x 
3-4  mm.),  nearly  of  the  same  shape  as  the  minute  oonidia,  but 
many  times  larger,  in  which  condition  the  fungus  is  known  as  Yalsa 
ambiens,  and  has  been  found  on  Pear  and  Apple,  but  also  on  Maple, 
Beech,  Hazel,  Alder,  Plum  and  Cherry,  Elm,  Oak,  Hawthorn,  Poplar, 
Chestnut,  Lime,  and  even  on  Rose.  Hence  it  is  widely  diffused  and 
well  known.  It  would  be  a  dangerous  enemy  if  once  it  became 
established  as  a  parasite  on  living  fruit  trees.  The  mature  con¬ 
dition  may  be  found  late  in  the  autumn,  in  the  winter,  and  the 
early  spring.” 
Oloire  de  Dijon  Rose  proliferous. — Mr.  Chapman  exhibited  flowers 
having  their  centres  occupied  by  a  green  tuft  of  leaves,  &o.  He 
observes  that  of  about  two  dozen  plants,  the  whole  of  the  flowers  this 
year  and  for  several  years  previously  have  developed  the  peculiarity. 
Birch  tree  bark  diseased. — Mr.  A.  Walker  of  The  Croft,  Needham 
Market,  Suffolk,  sent  some  specimens,  whioh  Mr.  Saunders  undertook  to 
examine. 
Cattleya  Mendlei  malformed. — Flowers  were  sent  by  Sir  Trevor 
WILD  FERNS  IN  DEVONSHIRE. 
(See  notice  of  “Gardening  for  Beginners,”  page  539.) 
Peach  blister. — Dr.  Bonavia  sent  leaves  badly  attacked  by  this 
oommon  disease,  Exoascus  deformans. 
Apple  bark  tendrils. — Mr.  F.  Marsh  Read  sent  a  piece  of  Apple 
bark  covered  with  golden  twisted  threads.  He  observes  that  “  the 
main  stem  for  about  6  feet  from  the  soil  is  ‘  ribboned  ’  with  it.”  Dr. 
Cooke  reports  upon  it  as  follows: — “Portions  of  the  bark  of  living 
Apple  trees  were  sent  for  information.  The  bark  was  covered  with 
long  yellow  tendrils  or  filaments,  thin  as  a  hair,  and  much  contorted 
and  interwoven  together,  presenting  a  very  singular  and  conspicuous 
appearance.  Upon  examination  a  number  of  compound  cells  may  be 
seen  in  the  bark,  each  with  an  external  orifice,  from  which  the  golden 
tendrils  protrude.  These  tendrils  are  composed  of  myriads  of  very 
minute  oonidia,  or  spore-like  bodiep,  adhering  to  each  other  as  they 
exude,  and  are  at  first  soft  and  flexile,  but  soon,  on  becoming  dry,  the 
tendrils  are  brittle  and  horny,  or  hair-like,  variously  twisted  and 
contorted,  little  thicker  than  a  human  hair.  The  number  of  very 
minute  spore-like  bodies  composing  each  tendril  must  be  enormous 
(each  5  micromillemetres  long,  and  slightly  curved).  The  fungus  has 
long  been  well  known  on  pomaoeous  trees,  but  we  have  not  met  with 
it  before  upon  living  bark.  It  is  known  as  Cytospora  carphosperma. 
Later  on  the  same  pustules  are  occupied  by  a  spbceriaceons  fungus, 
which  is  believed  to  be  the  ultimate  development  of  this  dimorphous 
organism,  and  in  this  condition  each  pustule  consists  of  a  few 
flask-like  oonceptacles  or  perithecia  with  rather  long  converging 
necks.  These  perithecia  enclose  numerous  delicate  cylindrical  sacs, 
Lawrence,  as  well  as  of  Odontoglossum,  which  Dr.  Masters  undertook 
to  report  upon. 
Thistle  fasciated. — Mr.  Houston  showed  an  abnormally  large  speoimen 
of  this  common  monstrosity. 
Richmond  Horticultural,  Jui|e  26tl|. 
Yesterday  the  Old  Deer  Park  at  Richmond,  Surrey,  contained  five 
great  marquees,  (there  were  close  on  a  score  altogether),  within  which 
were  staged  magnificent  exhibitions  of  general  horticultural  produce, 
under  the  auspices  of  the  above  society.  The  Old  Deer  Park  is  an 
ideal  place  for  a  flower  show.  It  is  level,  smooth,  and  open,  lying 
between  the  River  Thames  and  the  pretty  town  of  Richmond  itself. 
The  sphere  of  this  horticultural  society  embraces  besides  Richmond,  the 
parishes  of  Twickenham,  Islewortb,  Mortlake,  East  Sheen,  Kew, 
Petersham,  Ham,  Barnes,  and  Roehampton — a  whole  district  in  fact, 
thickly  dotted  with  aristocratic  demesnes,  and  fine  gardens.  The 
nurserymen  from  around  London  can  more  or  less  all  send  their  exhibits 
by  road  vans. 
On  this  occasion  the  National  Rose  Society’s  southern  exhibition 
was  held  in  conjunction  with  the  Richmond  Show,  so  that  Roses  formed 
a  very  special  feature.  A  finer  day  than  that  of  Wednesday  oould  not 
have  opened,  and  we  sincerely  hope  the  Society’s  exchequer  may  have 
been  well  replenished.  Last  year  was  rather  unfortunate  in  this  respect. 
The  plan  of  having  the  exhibits  of  each  tent  denoted  by  inscriptions  on
