SELECT LIST OF PLANTS 
With their Means of Increase. 
Asigs (Picea).—Propagation is effected principally by 
seed sown out of doors in April, sometimes by cuttings 
and by layers. The cones bearing the seeds should be 
quite mature when gathered. With certain kinds it is 
necessary to heat them in a kiln or an oven to cause the 
scales to open and so to release the seed. Care is 
necessary not to expose them to such a high temperature 
as would destroy the germ. 
ABUTILON.—Increase by cuttings in spring in sandy 
soil with a temperature of 65 to 75 degrees or by seed 
sown in pots or pans in gentle heat. 
AcaciA.—From seed sown when ripe after soak- 
ing in warm water. By cuttings of half-ripened wood 
in well-drained pots of sandy peat under bell-glasses in 
a cold frame or in heat, according to whether green- 
house or stove sorts. Some species have been reared 
from root-cuttings, such as A. melanoxylon. 
AcALypHaA.—Cuttings from stock plants in heat at 
almost any season. Roots form most quickly in spring. 
AcCANTHUS.-——Sow seed in gentle heat in spring, divide 
rootstocks in autumn. Root-cuttings also succeed if 
made 2 inches long and planted in pots of sandy loam. 
AcER.—Seedlings may be raised from seed sown as 
soon as ripe or stratified and sown in spring. The
