most important of these is the Ginseng, (Pmiax quinque folium), which is native 

 from eastern Canada to Alabama and in woods from Kentucky to Iowa, Mis- 

 souri, Nebraska and Minnesota. This species is now widely cultivated, large 

 quantities of Ginseng being exported to China, where the roots are in great 

 demand. The Chinese Gingseng is P. ginseng. Several other species are 

 used in medicine, among them the Spikenard (Aralia racemosa), and Wild 

 Sarsaparilla (^Aralia nudicaulis). These plants are not officinal, but they are 

 quite commonly used. They have aromatic and stimulating properties. Barring- 

 tonin, CjgH2jOj(OH)3, is found in Barringtonia, a Japanese Aralia, Panax, 

 and other genera. Araliin occurs in the roots of Fatsia horrida. The terpene, 

 oralien, Cj^H^^, occurs in Aralia nudicaulis. Some members of this order are 

 occasionally weedy, especially the Sarsaparilla. Rice paper is made from 

 Tetrapanax papyrifera, native to Formosa. It is a small tree about 10 feet high. 

 The tree is cut into to obtain the pith, which is divided into thin slices and the 

 paper cut with a sharp knife.

 A number of the plants of the family are of economic importance, among them
