little close for a short time after potting, 
when they may be given a fair amount of 
air in the early part of the day ; close the 
house in good time in the afternoons, and 
syringe them freely always when the air is 
shut off. This must not be omitted after 
growth has commenced and the weather 
gets at all warm, as they are very subject 
to red spider; but, by timely and con- 
tinuous syringing through the summer, 
no inconvenience will be experienced ; 
turn them round once a week, so that 
they may get their leaves regularly wet 
on all sides. They will probably not 
require anything more, except a regular 
supply of water to the roots when the 
soil seems to want it; do not let the 
latter become so dry before water is given 
asis necessary with plants of amore tender 
nature. 
If any shoots show signs of out-growing 
the others pinch out their points; give 
more air by the middle of August, but keep 
on using the syringe until the end of Sep- 
tember—it will not induce a soft condition 
of the wood, as with some things, and as 
this Clianthus is not much lable to mil- 
dew no harm will be done by the continued 
use of water overhead. Winter them as 
advised for the preceding season, and again 
pot in the spring ; this time, if they have 
done well, they will require a 3-inch shift, 
with soil as before recommended. Still 
keep the shoots trained out, using a few 
neat sticks to keep the branches in their 
wonted position, but it is a plant that does 
not need much support ; treat after potting 
and during the summer as last year. They 
will most likely flower from the principal 
shoots in July or August, consequently 
these must not be stopped, or the blooming 
will be interfered with ; when in flower 
they can be placed in the conservatory, 
where their bright-coloured blooms, dif- 
ferent in every way from most of the other 
occupants, will make them _ noticeable. 
After they have done flowering shorten 
the strong shoots back, and treat as during 
the previous autumn and winter. Again 
move them in the spring, giving pots as 
much larger as last season ; this summer 
the plants will make a good deal more 
erowth, from the increased root-power 
which they have attained, and will pro- 
duce more flowers. If the pots are well 
filled with roots the ensuing spring, and it 
is deemed advisable to grow them into 
large specimens, they may be again moved 
into bigger pots; but if moderate-sized 
plants are preferred give manure-water 
once or twice a week, and in the spring 
remove 2 or 3 inches of the surface soil, 
and replace with new, to which has been 
added one-fifth of rotten manure : treated 
thus they will last for years. 
This Clianthus makes a good plant for 
covering a back wall or clothing a pillar, 
either planted out or grown in a large pot, 
the principal thing being to keep it well 
and regularly syringed all through the 
growing season. Handsome as it is, with 
many growers it has got into bad repute, 
because it is subject to red spider ; this, if 
allowed to accumulate upon it, makes the 
leaves shabby and prevents free growth, yet 
nothing more is required to dislodge it than 
the free use of thesyringe, asalready advised. 
C. magnificus differs little in its flowers 
from the preceding, but is of a rather more 
vigorous or larger habit of growth. It re- 
quires the same treatment in every way, 
and is in some respects a better plant for 
training to a pillar or similar situation ; 
like C. puniceus, it must have a free appli- 
cation of the syringe. 
Insects.—These Chanthus are not much 
troubled with insects, except scale and 
spider, as already mentioned ; if they get 
affected with brown scale they should be 
occasionally well sponged over, and in the 
winter, when at rest, syringed with insecti- 
cide. If the white species of scale gets upon 
them there is no recourse but heading back 
into the hard wood when the plants are in 
a dormant state, and washing repeatedly 
with a strong solution of insecticide. Should 
they be attacked by aphides, fumigate.

Where quick-growing evergreen green- 
house climbers, such as will cover a large 
space in little time, are required, these 
plants suit. Although their flowers are 
not showy they are borne in the greatest 
profusion, and from their graceful droop- 
ing habit of growth they are very effective. 
Cobzeas may be propagated either from 
seeds or cuttings; if the latter course is 
adopted pieces about 3 or 4 inches long 
should in spring be taken off with a heel 
and put in small pots in a mixture of sand 
and loam, in moderate heat under a bell- 
glass. Kept moist and shaded they will 
root in a short time, and when the soil is 
fairly filled with roots move them into 
pots 6 or 7 inches in diameter, using 
ordinary sandy loam well enriched with 
rotten manure. Each plant should have a 
tall stick to support the shoots ; after they 
have begun to grow freely a greenhouse 
temperature will be best; give air daily 
and water sufficient to keep the soil moist, 
and sprinkle overhead every day with the 
syringe. By the end of July the plants 
should be large enough for turning out
