under bell-glasses, in strong moist) 
heat, with scions of the young wood, 
on stocks formed of cuttings struck 
the same season. From the Ca- 
mellia being an evergreen, and its 
leaves being large, dark-green, and 
shining, it makes a very fine ap- 
pearance against a conservative 
wall; and no plant whatever is| 
more magnificent in a conservatory. 
It must be observed, that all the va- 
rieties of C. juponica cannot bear 
too much heat, and they prefer the 
shade to broad sunshine; also that 
when they are planted against a 
wall, it is better with a southeast 
aspect than full south. C. Sasdn- 
qua, and iis beautiful variety, C. S. 
malificra, are the most tender. C. 
reticulata is quite a different spe- 
cies from C. japonica; and it is 
certainly a-noble plant, from the 
large size and brilliant colour of the 
flowers. It was first thought ten- 
der, but it is now found to be quite 
as hardy as C. japonica, only re- 
quirmg a slight protection during 
winter. [The Camellia cannot be 
safely trusted in the open air during 
winter in any part of this country 
north of Charleston, 8. C.—Eb.]

Keeautir ul herbaceous plants, natives

of Europe and Asia; the greater 
part of which are perennials, and 
are hardy in British gardens. There 
are also some handsome hardy bien- 
nials and annuals, and one or two 
greenhouse species. Many of the 
hardy perennials are dwarf plants, 
which produce a profusion of flow- 
ers, more conspicuous than the 
The French nurserymen have | 
C. pyramiddlis, the pyramidal Bell- 
flower; C. Trachélium, the Throat- 
wort, &c. C. pyramiddlis is one 
of those plants that by repeated 
repotting can be brought to an ex- 
traordinary size, either as a nar- 
row cone covered with deep blue 
flowers from the base to the sum- 
mit, or trained against a frame in 
the fan manner. By either mode 
it makes a very splendid object ; 
and all the art required to produce 
it, consists in employing rich soil, 
and in shifting the plant for two 
years into pots always a little 
larger and larger, so as to prevent 
it from coming into flower till it 
has acquired extraordinary vigour. 
Some of the prettiest little species 
for pots, or rockwork, are C. ceni- 
sia, and C. unifléra, which dazno 
exceed three inches in height, and 
are covered during June or July 
with blue flowers; C. carpdthica 
C. rotundifolia, C. gargdnica, ane 
upwards of fifty others, which do 
not exceed six inches in height. Adl 
these are very valuable for forming 
beds in a geometric or regularly- 
shaped flower-garden, from their 
dwarf and compact habit of growth, 
and from the great profusion of 
their Jeaves and brilliant-looking 
flowers. C. médium, the Canter- 
bury Bell, is one of the most orna- 
mental of biennials; and C. Spécu- 
lum, Venus’s Looking-glass, is a 
well-known and pretty annual. 
This last species has been, how-
