300 PLANTS OF NEW ZEALAND 



Araliaceae. 



The Family of Akaliads, or Ivyworts. 



Distribution. — This family is closely allied to the Umbelliferae, but is 

 chiefly tropical in its distribution, though some species are found in Canada, 

 N.W. America and Japan. The New Zealand species are all endemic. The 

 British Hedera Helix, the Common Ivy, is well-known, and much cultivated. 

 The berries are emetic and purgative. TetrapaJiax x>o.pyrifera furnishes the 

 rice-paper of the Chinese. The stems of this plant, which is found only in 

 the island of Formosa, are filled with a pure white pith, from which the 

 paper is made. This pith is also used in the making of artificial flowers. 

 Some of the species of Aralia have slight medicinal properties.

We have followed Engler and Prantl {Pflanzenfamilien III., 8, 57) in 

 placing Kirk's Aralia Lyallii under the genus Stilbocarpa, thus restoring it to 

 the position originally given it by Mr. J. B. Armstrong.
