UMBELLALES — UM BELLI FERAE 647 most important of these is the Ginseng, (Pmiax quinquefolium), 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. Umbeixiferae. Carrot Family.
