The primary root is strong; the adventitious roots may some- 

 times also become strong, and then new plants may be produced 

 by their agency (Haglund). Dormant buds occur.

 which arise from the base ; these shoots die after a period 

 of three to four years and are replaced by three to four new 

 shoots near the apex (compare also Sylvén).

Not until then, and therefore when it is several years old, 

 does it appear that the plant flowers. According to Haglcnd 

 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
