the glass so that they may not be drawn up weakly. 
When potting off, keep the corms well up to the surface 
and grow on in a temperature of 60 to 65 degrees. The 
hardy kinds can be also raised from seed sown in a cold 
frame in October, to transplant the following year. 
CypERUS.—Propagate by seed and division. The 
Umbrella Plant (C. alternifolius) can also be increased 
by shortening the leaves of the crowns and planting 
them with an inch or two of the stem in moist, light 
compost to induce growths to start from the axils of the 
leaves. 
Cytisus.—The greenhouse kinds, such as C. race- 
mosus, now called C. elegans, so largely grown for 
market, are propagated from cuttings, about 3 inches 
long, of young wood with a heel in a close, warm frame 
in spring. The hardy kinds are reared from seed, by 
cuttings of half-ripened shoots in a warm case, by 
layering in October, and by grafting on the Common 
Laburnum in March and April. 
DactyLis.—The variegated form of Cock’s-foot Grass 
is somewhat extensively employed in bedding. It is 
propagated by division of the tufts in October or April, 
as seed cannot be relied on to come true. 
Dauiia.—The principal methods employed in propa- 
gating these popular plants are by cuttings, by division 
of the roots when planting, by seed, and rarely by 
grafting. To obtain an abundant supply of cuttings, 
the roots are brought from their place of storage in 
spring, placed on a gentle bottom heat, and thinly 
covered with leaf-mould or soil, the crowns being left 
bare. A slight moisture, with warmth and daily syring- 
ing, induces the young shoots to grow plentifully ; these, 
taken off and inserted as cuttings, when 2 or 3 inches
