THE FLOEIST AND POMOLOGIST. 
[ January, 
summed up in a few words. A good founda¬ 
tion must be laid, by placing the tree in tlie 
right kind of compost. They are not over¬ 
particular as to this, but to do them well, tough, 
fibry, yellow loam must ho procured from an 
upland pasture. It is best to use this before the 
fibre is too much decayed ; pull it to pieces hy 
the hand, and to five-parts of loam add one part 
of rotted stable-manure, and to each barrow-load 
an 8-inch pot full of crushed bones. If the 
trees are large, inch bones are the best, but for 
small trees we prefer the bone-meal or dust 
that is sifted through a half-inch sieve. It is 
also desirable, though not absolutely necessary 
to ensure success, to add a portion of broken 
charcoal to the compost. Drain the pots well 
by placing clean potsherds at the bottom, and 
over them a layer of fibre from which the finer 
particles of soil have been sifted ; this is to keep 
the drainage perfect, by preventing the finer 
particles of the compost from working down 
into it. After the tree has been turned out of 
the pot in which it had been growing previously, 
with a pointed stick pick out the old material 
that had been used for drainage, and most of 
the old effete soil. The tree should not be 
potted deeper than it had been previously, 
and the compost must bo pressed firmly 
round the ball with a wooden rammer. 
After potting the plants must be placed 
in a warm house, but it is not well to 
water the soil for a day or two, especially 
if the roots were not in a very healthy con¬ 
dition at the time of potting. The house may 
bo kept rather close, and the trees be syringed 
until the roots begin to work into the new 
compost: this care is applicable to summer 
potting; in winter it is unnecessary. When the 
roots are active and have taken firm hold of 
the sides of the pots plentiful supplies of water 
are necessary, and the trees ought to be 
syringed well twice daily. 
The insect pests that attack Orange-trees are 
scale and mealy bug, both of which will thrive 
on them. A clammy fonnation also gathers on 
the upper surface of the leaves in consequence 
of the presence of scale. To remove them I 
do not find any better plan than to wash the 
leaves and wood v T ith tepid water in which 
soft-soap has been dissolved. The constant 
syringing keeps the trees healthy, but this 
must be discontinued when the fruit begins to 
change for ripening. A rather dry atmosphere 
is desirable when the trees are in flower, as the 
fruit does not set well in a moist close atmo¬ 
sphere early in the year. 
There is another variety of dessert Orange 
besides those already named that ought to bo 
in every collection. It has been grown by 
some persons for many years, and when culti¬ 
vated under the. best conditions it is superior in 
flavour to any other. This is named the Prata 
or Silver Orange. 
By following the above cultural directions 
success will be ensured, and the pleasure to he 
derived from successfully cultivating these 
fruits is very great.—J. Douglas, Loxfortl

SADLEEIA CYATIIEOIDES. 
ADLERIA is one of the few genera of 
Ferns which, though long since known to 
botanists, has remained unrepresented in 
our living collections till within the last year 
or two. Latterly it has been imported in a 
living state both by Mr. Bull and Mr. Williams, 
and may now be regarded as established in our 
gardens. Its native country is the Sandwich 
Islands, where two or three forms of doubtful 
distinctness occur. 
The Sadleria cycitheoides forms one of the 
dwarfer-stemmed of the arborescent ferns, and 
is remarkable for its graceful habit, combined 
with its stout-textured and somewhat bold and 
arching fronds. Mr. Bull’s figure, lvhich we 
annex, gives a good idea of its elegant style of 
growth, the plant represented being not yet 
old enough to have formed its stem or trunk. 
In its more mature state it has an erect trunk¬ 
like stem of moderate thickness, and some 3 ft. 
in height, the crown of which is densely 
packed with linear dark-coloured scales, which 
also surround the base of the elongated and 
arching stipes. The fronds are 4 ft. to 6 ft. 
long, with pinnae 8 in. to 12 in. long, and 
three-fourths of an inch broad, cut down 
to the rachis into numerous linear pinnules 
about half an inch long. The fructifica¬ 
tion is that of Blechnum ,—that is to say, the 
receptacle is central and elevated; and forms a 
continuous line close to and on both sides the 
midrib of the pinnules, and on this the spore- 
cases are seated, each line being covered while
