Varigated  Leaves 
The  Missouri  Botanical  Garden  Bul¬ 
letin  for  December,  1015,  has  an  inter¬ 
esting  discussion  of  vaiicga tion  in  fol¬ 
iage.  Anything  that  induces  chlorosis  by 
interfering  with  the  formation  of  “leaf 
green”  or  chlorophyll  is  a  serious  matter 
for  the  plant.  Most  variegated  varieties 
have  originated  from  cuttings  made  from 
branches  showing  this  peculiarity,  which 
is  due  to  a  variety  of  causes;  absence  of 
sunlight,  deficiency  in  chemical  salts 
needed  to  produce  chlorophyll,  mechani¬ 
cal  injury,  etc.  This  sort  of  variegation, 
Selaginella  Kraussiana 
however,  is  regarded  as  different  from 
true  chlorosis.  It  now  appears  that  there 
are  two  forms  of  true  variegation  or 
chlorosis,  the  infectious  and  non-infec¬ 
tions  and  one  plant,  Ihionymus  Ja pont¬ 
ons,  was  found  to  possess  both  infectious 
and  non-infections  forms.  It  has  been 
found  that  jn  some  cases  a  normally 
green  stock,  grafted  with  a  variegated 
scion,  would  later  produce  variegated 
foliage,  while  with  some  plants  it  is  im¬ 
possible  to  produce  any  effect  on  the 
stock,  even  though  grafted  with  a  varie¬ 
gated  variety.  Also,  some  varieties  seem 
immune  to  the  infectious  chlorosis, 
which  is  readily  transferred  to  other 
closely  related  forms.  Among  familiar 
plants  showing  non-infections  variega- 
Fittonia  Argyroneura 
tion  arc  striped  and  banded  grasses,  as 
well  as  many  decorative  greenhouse 
plants. 
The  club  moss  shown  above.  Sela- 
ginclla  Kraussiana,  is  pictured  in  the 
Bulletin  as  an  iutorestilig  example  of 
apparently  infections  chlorosis.  The  pe¬ 
culiar  effect  of  such  ivory-white  variega¬ 
tion,  often  including  a  considerable  por¬ 
tion.  contrasted  with  the  normal  vivid 
green,  makes  such  plants  extremely  decor¬ 
ative.  Such  variegated  forms  are  propa-  , 
gated  by  cuttings,  but  not  inherited  j 
through  the  seeds.  The  variegation  due  i 
to  non-infections  chlorosis  is  perpetuated  ; 
through  the  seed.  We  are  told  that  if 
the  juice  of  a  plant  like  tobacco,  hav¬ 
ing  an  infectious  chlorosis,  comes  in 
contact  with  a  wound  on  a  normal  plant 
of  the  same  kind,  the  latter  may  shortly 
show  symptoms  of  the  disorder,  which 
spreads  rapidly.  It  is  also  asserted  that  | 
l 
dried  specimens  retain  their  ability  to 1 
communicate  the  disease  for  two  years. 
A  number  of  crops,  including  beets,  to¬ 
bacco  and  tomatoes,  suffer  seriously  from 
chlorosis  diseases,  which  include  “mo¬ 
saic  disease”  of  tobacco  and  tomatoes.  It 
will  be  seen  that  investigations  into  the 
general  subject  of  plant  variegation  or 
absence  of  chlorophyll  may  have  far- 
reaching  value. 
Perhaps  the  most  remarkable  examples 
of  plant  chlorosis  are  shown  by  some  of 
the  beautiful  Brazilian  Caladiums,  rel¬ 
atives  of  the  robust  garden  elephant’s- 
ear,  that  are  grown  for  conservatory  dec¬ 
oration.  Some  show  such  an  entire  ab¬ 
sence  of  green  coloring  matter  that  their 
foliage  resembles  translucent  silvery 
parchment,  so  clear  and  transparent  that 
clear  newspaper  type  may  be  read 
through  it.  These  plants  also  include 
many  vivid  shades  of  crimson  and  rose. 
Tlie  pretty  little  plant  shown  in  cut 
below.  Fittonin  argyroneura,  sometimes 
grown  in  a  Wardian  case  or  warm  win¬ 
dow  garden,  shows  a  peculiar  variega¬ 
tion  of  pure  silvery  white'  extending  to 
the  veins  of  the  leaf  only.  There  is  an¬ 
other  handsome  Fittonia,  F.  Yersehaf- 
felt.ii,  in  which  the  veins  are  bright  car¬ 
mine. 
New  Plant  Immigrants 
In  the  fifth  annual  list  issued  by  the 
Office  of  Foreign  Seed  and  Plant  Intro¬ 
duction.  U.  S.  Department  of  Agriculture, 
is  given  a  brief  description  of  the  Tung  oil 
or  wood  oil  tree  of  the  Yanktse  Valley, 
China.  The  large  seeds  are  borne  in 
fruits  the  size  of  small  apples,  and  give 
2N  per  cent,  of  one  of  the  best  drying 
oils  known.  Large  importations  of  this 
oil  are  made  into  this  country.  Tt  is  a 
deciduous  tree,  botannally  Aleurites 
Fordii,  which  bears  white  bowers,  and  en¬ 
dures  frost.  II  has  fruited  near  Talla¬ 
hassee,  Flu.  The  fruit  is  not  edible.  An¬ 
other  variety  is  the  candle  nut  of  the 
Philippines.  Aleurites  moluecana.  'Phis 
is  a  strictly  tropical  tree  of  attractive 
appearance,  tin*  seeds  yielding  a  quiek- 
dr.vitig  oil.  The  lmlf-ripe  kernels  are  also 
Considered  desirable  when  roasted. 
The  Quetta  nectarine,  received  by  the 
Department  from  Quetta.  India,  has  been 
fruited  in  California,  and  is  said  by  ex¬ 
perts  to  bo  exceptionally  line.  It  is  thiu- 
skiimed,  but.  is  of  large  size  and  good 
color. 
The  Japanese  vegetable  udo  {Arnlia 
conlatal,  is  described  as  suitable  for  wide 
Cultivation  for  its  blanched  edible  shoots. 
Planted  three  to  four  feet  apart  it  is 
bushy,  yielding  edible  shoots  for  nine 
years.  The  shoots  are  blanched  by 
mounding  with  earth  or  covering  with 
drain  tile  in  early  Spring.  The  shoots 
are  peeled,  sliced  into  ice  water,  and  then 
served  with  French  dressing,  or  boiled  i 
and  served  like  asparagus. 
The  Office  of  Foreign  Seed  and  Plant 
Introduction  announces  that  it  has  water¬ 
melon  seeds  from  Chinese.  Roumanian, 
Siberian  and  Caucasian  sources  <>n  hau  l,
