enough to allow of the extension they will 
make during the season, as it is not neces- 
sary to move them again before the spring 
comes round, when larger pots may be 
given proportionate in size to that which 
the plants are required to grow to. Give 
plenty of water through the growing sea- 
son, and shade carefully from the sun ; 
keep the atmosphere moist, admit a mode- 
rate amount of air daily, and moisten them 
overhead with the syringe in the evenings 
through the growing season. The soil in 
which they are grown is all the better for 
having a good sprinkling of potsherds, 
charcoal, or coal cinders mixed with it; 
any of these will answer in keeping the 
soil from getting sour, with the large 
amount of water required when the plants 
are in active growth. All the difference 
needed in the treatment of the warm and 
the cooler section is that the former should 
have a night temperature in the winter of 
from 54° to 58°, whereas the cooler species 
will not want more than 45°, with in the 
case of both a proportionate rise in the day; 
im summer a night temperature of 60° to 
65°, with more by day according to the 
state of the weather, will answer for the 
warm division, and that of a warm green- 
house for the cool sorts, but even these 
usually look fresher for a little extra 
warmth.

handsome species, that require the most

This handsome stove Acanthad is another 
of the select number of plants whose time 
of flowering occurs during the autumn or 
winter months, and on this account it is 
especially valuable. Its bright red tube- 
shaped flowers are produced freely from the 
points of the shoots of the current season’s 
growth. It has a somewhat erect habit, 
but by attention to stopping in the younger 
stages of growth it assumes a bushy form. 
It is one of those quick-growing plants 
that are usually propagated annually in 
the spring for flowering in the ensuing 
winter, a mode of treatment by many con- 
sidered preferable to that of growing the 
old plants on a second season, although by 
the latter course they can be had in a 
larger state. It forms a handsome object 
in the stove during the dull season, and 
the flowers when cut will stand fairly well 
if the previous treatment of the plants has ~ 
been such as to enable them to attain all 
the strength of which they are capable. 
Cuttings made from the young shoots 
which the plants, after blooming, will pro- 
duce in ordinary stove heat, taken off in 
March and treated in the usual way in a 
moderately moist, confined atmosphere, 
will soon strike root; then put them singly 
into 4-inch pots, pinch out the points as 
soon as they begin to grow, and repeat this 
when a second growth has been made. As 
in the case of other quick-growing plants 
it is necessary to give it plenty of light, 
otherwise a weak condition is sure to 
follow. A single shift from the pots they 
are now in to those in which the plants 
are to bloom will be enough ; this should 
be given them about the end of May; 8 or 
9 inch pots will suffice, as when the soil 
gets full of roots they can be kept going 
by the use of manure-water. A low pit 
where they can be near the glass will be 
the best place onwards after the second 
potting, giving air freely in the middle of 
the day, during which time the plants will 
bear a day temperature of from 70° to 80°, 
with from 60° to 65° at night. Syringe 
daily to promote growth and keep down 
insects, using a thin shade when the sun is 
very bright; the shoots should be again 
stopped as soon as the roots have got esta- 
blished in the soil. The treatment re- 
quired through the summer will be of a 
routine character until September; then 
give more air and expose the plants to all 
the light possible with a view te solidify- 
ing the growth and checking a disposition 
to over-lengthening of the shoots. As the 
days get shorter reduce the temperature in
