their development, will infallibly cause 
them to fall off. A temperature of about 
65° is the most proper for such as are 
desired to flower in the following win¬ 
ter; 45° or 50° will be Sufficient for the 
next, or those which may be said to bloom 
naturally, while the portion required to 
furnish flowers for the late spring months 
should be placed out of doors. This 
treatment must be continued until the 
new growths are completed, and the in¬ 
cipient blossom-buds can be discovered, 
when a cool, shaded situation, as recom¬ 
mended at the beginning of this article, 
should be provided for each section as 
they require it; observing to supply them 
bountifully with water during the whole 
period of growth, with an occasional 
sprinkling over the foliage, and constant 
shade. Any situation secure from frost 
will preserve them through the winter, 
and, as the flowers are expanded, the 
plants may be removed wherever their 
presence may be deemed most ornamental. 
Camellias may also be grown without 
protection in the open ground, For this 
purpose a northern aspect should be se¬ 
lected for them, that their season for 
flowering may be retarded as long as 
possible, or the flowers are liable to be 
injured by the frosts in spring. 
To obtain new varieties recourse is 
had to raising seedlings. The seed can 
only be obtained from the single or semi¬ 
double kinds, such as the o]d reds, or 
Waratah; these impregnated with pollen 
from any kind from which it can be 
had, will produce a few seeds; the 
latter part of the business is the most 
difficult, as so few of the double va¬ 
rieties have any anthers. The seed is 
sown as soon as it is ripe in pans of sandy 
peat, and plunged in a gentle heat; the 
plants obtained are afterwards potted and 
treated as has been described until they 
flower, when a large proportion are 
usually single, and therefore worthless, 
except for grafting esteemed varieties 
upon. This is the most usual mode of 
propagation, though plants may be had 
from cuttings. The latter are struck in 
pots of sand, placed in a cool pit or frame, 
though it is a tedious operation. Increase 
is much more readily effected either by 
grafting or inarching, either of which 
should be done as soon as the new wood 
is firm enough to handle: the subjects 
operated on should be placed in a close, 
humid, and somewhat raised atmosphere, 
such as is afforded by a common hand¬ 
glass placed over a bark-bed. The union 
takes place in a few weeks, and with 
encouragement the scions will form fine 
plants in one season. The following are 
preferable varieties : Alba plena , CJian- 
dlerii , Colvilii rubra, Donkelaarii, Double 
Red, Eclipse, Fordii, Gloria mundi, Gile-

CAMEHARIA (Linn.) Nat. Order 
Apocynacece. Handsome flowering plants, 
easily grown in an ordinary stove; their 
flowers are white or orange, and they 
may be propagated either by cuttings or 
from seed. 
CAMPANULA (Linn.) Nat. Ord. 
Campanulacece. In this genus we are 
presented with a most extensive assem¬ 
blage of really beautiful forms, most of 
them too of the easiest culture in the 
open ground. Campanulas form an im¬ 
portant feature in the flora of nearly 
every country in Europe, nor are our 
own pretty C. rotundij'olia, C. trachelium, 
and their varieties, inconspicuous even 
among the multitude of species; the 
former, though frequent on every common, 
is never passed without a glance of ad¬ 
miration even from the most indifferent. 
In a cultural sense the genus may be 
divided into three sections : the tender 
kinds requiring to be grown in the green¬ 
house, at least through the winter, the 
hardy perennial kinds, and those of an¬ 
nual duration. The first occasion but 
little trouble, if grown in pots of rich 
loamy soil, and encouraged with occa¬ 
sional waterings of liquid manure; they 
form handsome ornaments for balconies 
or similar places through the summer, 
and in winter should be kept nearly dry 
in a situation where they can receive 
the light without prejudice from frost; 
among tliis class is the well-known C. 
pyramidalis, an ancient favorite for deco 
rating halls, &c.; along with it may be
