oil upright spikes; they are for the most 
part brown, spotted, and blotched with 
yellow, but all are deliciously fragrant. 
For culture it may be referred to the 
preceding genus. 
CYNOGLOSSUM (Linn.) Nat. Or. 
Boraginacea . Pretty border plants, pro¬ 
ducing flowers of almost all colours; 
they grow in any common soil, and are 
not very particular as to situation; in¬ 
crease is readily obtained by division of 
the stools in spring. 
CYPRIPEDIUM (Linn.) Nat. Or. 
Orchidacees. Curious dwarf species of 
the terrestrial class; the sepals and pe¬ 
tals are broad and expansive, the lip 
large and helmet-shaped, and the colour 
of the whole green, blotched and barred 
with purple. They are easily grown in 
rough peat, in a somewhat lower tempe¬ 
rature than is necessary for most other 
plants of the order. 
CYRTANTHUS (Aiton.) Nat. Or. 
AmarylUdacete. Yery handsome green¬ 
house bulbs, with red, crimson, or orange- 
coloured flowers; the plants require to 
be potted in sandy peat and loam, and 
to have an airy station where abundance 
of light can be admitted through the 
summer, and in winter they should be 
kept dormant. 
CYRTOCHYLUM (Kunth.) N.O. Or- 
chidaceee. A genus of beautiful epiphytes, 
whose flowers closely resemble those of 
Oncidium; they succeed in pots of light 
eat and moss, having the base of the 
ulbs elevated two or three inches above 
the rim of the pot. In the growing 
season they should be liberally watered, 
and, by raising the temperature of the 
house in the early part of the day, al¬ 
lowance is made for the admission of air 
for an hour or two about noon, which 
will be found most beneficial to the young 
pseudo-bulbs, and, as they draw towards 
maturity, the supply may be increased, 
and a diminution of water take place, 
which will leave the plants in the re¬ 
quired dormant condition most conducive 
to the free production of flowers in the 
ensuing season. 
CYRTOPODIUM (R. Brown.) Nat. 
Or. Orcliidacea. Another genus of Or¬ 
chids of noble character, their pseudo¬ 
bulbs being, when well grown, from 
three to four feet in height, and the 
flower scape as much more, containing 
several hundred richly scented yellow 
blossoms. The plants require large pots, 
filled with the usual compost, which must 
be thoroughly incorporated and well 
drained; the temperature should be for 
the average 75° through the growing sea¬ 
son, and if bottom heat can be applied 
at this time, the plants will be much 
benefited. In the winter they may be 
kept nearly or quite dry, reducing the 
heat to an average of 60°; with this 
treatment the new shoots are developed 
with great vigour, and the production 
of flowers becomes a matter of certainty. 
DAHLIA (Cavanilles.) Nat. Ord. 
Composites. In no particular instance 
has the skill of the florist ever been 
more forcibly evinced than in the culture 
of this genus. In 1789 the first species, 
I), superjiua , was introduced, a tall un¬ 
sightly plant, with one wliorle of flo¬ 
rets, or, as it is commonly termed, a 
single flower, and from this have sprung 
the multitudinous varieties which now 
grace our gardens with their nume¬ 
rous large brilliant blossoms through¬ 
out the end of summer and autumn. To 
affect an indifference to the progress of 
the art of hybridizing, with such splen¬ 
did results of its practice apparent on 
every side, must require a stoicism 
we do not envy. The months of Ja¬ 
nuary and February may be regarded as 
the commencement of the Dahlia- 
grower’s operations; the roots are then 
drawn from their resting place, aud after 
being carefully examined, all traces of 
rottenness removed, and the labels made 
right, they are either potted and plunged 
into a gentle hot-bed, or placed in the 
heat without other preparation. As soon 
as the new shoots have grown from two 
to three inches in length, they are taken 
off with a sharp knife, the heel or base 
of the cutting pared square, and then 
placed by itself with its name into a 
small pot filled with sand, leaf-mould, 
and loam. Each cutting, as it is potted, 
should receive a gentle watering, and be 
immediately returned to the hot-bed,
