Greenhouse and Stove Plants. 
IMANTOPHYLLUM, 
longer without change or addition of soil, 
but the experiment was cut short through 
unforeseen circumstances. 
If it is thought advisable to grow some 
on to a larger size, they should when done 
blooming be moved into pots proportionate 
to the size they are wanted to grow to, say 
9 or 10 inches the first year; but for 
general use, to produce plants to flower in 
a small state with single heads, nothing 
equals the appearance of the autumn-struck 
cuttings that have been produced out-of- 
doors, for which the above two forms of H. 
hortensis are the best adapted. 
The variegated forms of H. japonica, H. 
Japonica argentea variegata, and H. japo- 
nica aurea variegata, are well worth cultiva- 
tion for the beauty of their leaves, as well 
as the flowers they produce. 
H. Otaksa. A very fine variety with 
large flowers, also suitable for pot-culture, 
like those already described, and of easy 
cultivation ; itis propagated from half-ripe 
shoots and grown in ordinary soil, either 
peat or loam, with one-eighth sand to keep 
such thirsty subjects from getting sour and 
waterlogged ; the plants should be exposed 
in the after part of summer in the open 
air to keep them dwarf and to get the wood 
ripened. 
H. paniculata. A white-flowered beauti- 
ful species that does well under pot: 
culture ; it isa most profuse free-blooming 
plant, that deserves to be generally known 
and much more generally grown than it is. 
H. stellata flore-plena. Another fine 
Japanese variety, producing very large 
corymbs of double rose-coloured flowers, 
and is in every way a desirable plant ; 
treatment same as for the preceding. 
H. Thomas Hoga. A very handsome 
kind that has recently appeared. It is a 
free-flowerer, producing moderate-sized 
heads of white flowers. 
The system of propagation and general 
treatment advised for the other species will 
answer for these, except that where the 
plants are required to be grown to a con- 
siderable size they must be encouraged by 
more pot-room. 
With less trouble Hydrangeas may be 
struck from cuttings produced in spring 
from plants that have been flowered early ; 
these should be taken off when they have 
three or four joints, and put singly in 
3-inch pots filled with half sand and loam. 
Stood in an intermediate heat, kept close, 
moist, and shaded, they will root in a few 
weeks, when give more air and as soon as 
the pots are fairly filled with roots put in 
others from 6 to 8 inches in diameter, 
using good loam, well enriched with rotten 
manure and with some sand added. When 
well established in these move to the open 
air, and give water as required through 
the summer ; keep in a pit or frame away 
from frost during the winter until required 
for forcing, or in the greenhouse to come 
on with solar heat for later blooming. 
InsEcts.—Hydrangeas are not much 
troubled with insects, except greenfly, 
which can be kept under by fumigating, 
dipping, or syringing with tobacco water. 
HYMENODIUM CRINITUM. 
A small-growing very distinct stove 
Fern ; the fronds are simple, that is with- 
out any divisions and about the size of a 
moderate example of Horse-radish, the 
surface studded over with black hairs. It 
is not elegant, but is desirable on account 
of its dissimilarity to other Ferns. It 
comes from the West Indies. 
For propagation and cultivation, see 
Ferns, general details of culture. 
HYMENOPHYLLUM. 
A beautiful genus of dwarf-spreading 
Filmy Ferns, requiring cool treatment, and 
to be kept always moist at the roots, and 
also in a moist atmosphere, such as present 
when covered with a bell-glass. They do 
not like much warmth, nor very much 
light.

IMANTOPHYLLUM. 
These are fine flowering evergreen green- 
house plants of close compact growth, that 
may be had in bloom during a good por- 
tion of the year where there is a sufficient 
quantity to keep up a succession, They 
force well, and on this account can be 
brought into flower during the winter so 
as to precede such as are let to come on 
later in a greenhouse temperature. The 
flowers are produced in large umbels on 
erect fleshy stalks that issue from the 
crowns among the leaves; they are a
