Cease syringing as the flowers begin to 
open, and when they are fully grown move 
to a greenhouse or elsewhere where they 
will be cooler, with a drier atmosphere. 
So treated the flowers will last fresh for 
many weeks. The two forms, the red and 
the white varieties, differ in nothing except 
the colour of the flowers, requiring similar 
treatment in every way. 
InsEcts.—Syringe to keep down red 
spider. For aphides fumigate. 
GONIOPHLEBIUM. 
A distinct and heautiful genus of Ferns, 
comprising stove and greenhouse species, 
many of them differing widely in size and 
appearance. In the Javenese G. subauri- 
culatum we have one of the most elegant 
drooping Ferns in cultivation ; the pendant 
fronds of a well-managed example of this 
kind will reach 8 or 9 feet in length. 
For propagation and cultivation, see 
Ferns, general details of culture.

GREVILLEA. 
The ornamental-leaved section of these 
are pretty decorative. plants, with finely 
divided elegant Fern-like foliage. They 
are well adapted for room or table decora- 
tion, or for mixing with flowering plants 
in greenhouses and conservatories. There 
are large numbers of species in existence, 
but only ‘a few are considered worth 
growing. Grevilleas are easily managed, 
and quickly reach the most useful size for 
general use, which is when from 15 to 24 
inches high. They are easily raised from 
seed, which should be sown about the 
beginning of February in shallow pans 
filled with fine sifted peat and sand ; sow 
the seeds thinly and cover very lightly. 
Stand in a temperature of 60°, keeping the 
soil slightly moist, and as soon as the 
plants are up keep them close to the glass. 
In a few weeks they will be large enough 
for putting singly into small pots, in soil of 
a like description to that in which the 
seecs were sown. Shade from bright sun, 
and keep the atmosphere moderately moist ; 
syringe overhead daily, and give air when 
the weather will permit. The temperature 
should now be kept about the same in the 
night as that in which the plants were 
raised, and allowed to rise by day more or 
less with the state of the weather. At the 
end of May move into 6-inch pots, and 
put a small stick to each plant to keep the 
stem straight; give air freely and keep 
them well up to the glass, with a little 
more shade as the sun gets more power ; 
be careful never to let the soil get dry, or 
the lower ieaves will suffer, and the appear- 
ance of the plants be spoilt. They will 
grow fast and by the latter end of summer 
will have reached a serviceable size, when 
they can be used for any purpose for which 
small handsome-foliaged plants are avail- 
able. In winter locate them in a house or 
pit where there is a temperature of about 
45° in the night, with less water, but on no 
account let the soil get dry. Such as are 
kept on to attain a larger size must have 
more pot-room in spring, and be given the 
usual greenhouse treatment this summer. 
After this they usually show a disposition 
to lose their bottom leaves, which detracts 
much from their appearance ; consequently 
young stock should be grown on each 
year. 
The two following kinds are most liked, 
and will generally be found sufficient :— 
G. robusta. From Port Jackson. 
G. rosmarinifolia. From New South 
Wales; a pretty plant, but not equal to the 
first-named. 
Insects.—Red spider sometimes affects 
Grevilleas, but can easily be kept down by 
a free use of the syringe. For thrips or 
aphides fumigate. 
GRIAS. 
These are evergreen trees requiring stove 
heat. They grow to a large size, attaining 
a height of 30 or 40 feet, and if to be seen 
in anything approaching a fully-developed 
condition they must have a very large 
house, such as devoted to tropical plants. 
They are increased by cuttings of the 
shoots which need a strong heat, and to be 
subsequently grown on with stove warmth 
until large enough to plant out, when they 
should have a good-sized bed composed of 
sandy loam. 
G. cauliflora. A large-growing species, 
producing the fruit known under the 
name of Anchovy Pear. It is a native of 
Jamaica. 
G. Fendlerti. A handsome-leaved species 
that bears yellow flowers. Introduced 
from Panama. 
G. zamorensis. Of this species little is 
known as to what its appearance will be 
when fully grown in a cultivated state,
