DESCRIPTIONS OF THE SHRUBS 



The plainest peculiarity of the plants is the sheath around the stem above

FIG. 529. Sacaline. 



* Bushy-growing plant with graceful curving stem 3-5 feet high ; leaves 



large, about as wide as long, and peculiarly square at base ; white 

 flowers abundant. SIEBOLD'S POLYGONUM (528) Polygonum 

 cuspidatum (P. Sieboldi). 



* Larger and more vigorous plants 8-12 feet high with larger and pro- 



portionally narrower leaves, sometimes a foot or more long, dis- 

 tinctly heart-shaped at base. This plant is too luxuriant and with 

 such a tendency to spread as to become a pest. SACALINE 

 (520) Polygonum sachaline'nse.

 nate leaves covered on one or both sides with silvery scales. These leaves 

 are either entire- or crisped-edged. The fruit is olive-like, 1-seeded. 

 There are many species in cultivation for the silvery foliage and the edible
