are called ‘‘ spawn.” Varieties that do not produce 
spawn may generally be induced to do so by slightly 
wounding or slashing the corm with a knife, but if so 
treated they must not be subjected to too much moisture 
when planted or they will rot. Cyclamens are best raised 
from seed, and the perennial corms so obtained will 
flower well a second season. Caladiums also belong to 
this section, and may be increased by division or by 
cutting out the growing eyes with a small portion of the 
fleshy mass and roots attached when growth is starting 
in early spring.

Tubers. 
Good examples of these underground fleshy stems 
covered with buds are the Potato and the Jerusalem 
Artichoke. It is well known that these may be cut into 
as many pieces to rear new plants as there are buds— 
generally called eyes—present. Or the sprouts of 
Potatoes, when number rather than size is desired, may 
be broken off and planted; and a second or a third crop 
will then quickly be ready for similar treatment. 
The large solid masses attached to Dahlias are not 
true tubers, as they do not bear buds, but are fleshy
