The primary root is strong; the adventitious roots may some- 
times also become strong, and then new plants may be produced 
by their agency (Haczunp). Dormant buds occur.

Not until then, and therefore when it is several years old, 
does it appear that the plant flowers. According to Haczunn 
the buds are naked, but I am of opinion that the short, 
brown and somewhat erect leaves, which usually decay quickly, 
and which occur at the base of each year’s shoot and are
