LIST OF PLANTS 103 
The silver-leaved kinds used for bedding are mostly 
raised from seed sown in gentle heat in February or 
March to plant out in May; also by cuttings of side- 
shoots in spring and autumn in a close frame with slight 
bottom heat, no water being applied over the foliage 
owing to their liability to damp off otherwise. 
Cissus.—Propagate in spring. When the. young 
shoots have grown a couple of inches long, cut them 
smoothly with an entire piece of the old wood just below 
a joint, insert in pots of sandy peat, plunge in bottom 
heat, and cover with a bell-glass in a temperature of 75 
to 85 degrees. | 
Cistus.—These are reared from seed sown early in 
spring with gentle bottom heat, also by cuttings, 3 or 
4 inches long, inserted firmly in sandy peat and covered 
with a handlight either in spring or autumn, with, of 
course, shade from sunshine. 
Cirrus.—The Orange family are chiefly propagated 
by budding, grafting, or inarching on seedling stocks 
raised from lemon or orange pips. August is a good 
time for the budding operation, and the worked plants 
are placed under handlights or in a close case with a 
bottom heat of 85 degrees. Either side- or splice-graft- 
ing is done in March. Inarching is effected whenever 
the branches are sufficiently firm, but not hard, and 
when the union is complete the parent is by degrees cut 
through until completely severed. 
CLEMATIS are principally propagated by grafting on 
fleshy roots of free-growing common species, such as 
C. Vitalba and C. flammula. The roots with some fibres 
attached are cut into lengths of about 5 inches, split 
at the upper end, and a wedge-shaped scion is inserted 
and tied with raffia; they are then potted and placed in
