404 CLASS XXIII. ORDER II. 



teeth; the corolla five petals, which are oval, reflexed and decid- 

 uous. Stamens five, with oblong anthers. Styles two, reflexed, 

 persistent; germ large, inferior, ovate-heart shaped, compressed. 

 The berries are kidney shaped, retuse at both ends, compressed, 

 of a bright scarlet color, crowned with the calyx and styles, and 

 containing two semii-ircular seeds. In most umbels there are 

 flowers with only one style, in which case the berry has a semi- 

 cordate form. Sometimes there are three styles and three seeds. 

 The outermost flowers ripen first, and their berries often obtain 

 their full size before the central ones are expanded. The middle 

 flowers are frequently abortive. There are also barren flowers, 

 on separate plants, which botanists describe as having larger 

 petals and an entire calyx. — In Northampton and on the Ascut- 

 ney mountain. — June, July. — Perennial. 



The root of Ginseng is in high estimation among the Chinese,
