Xiewisia rediviva, Pursh. 



North-Western America. The root of this herb is large and 

 starchy, was formerly extensively used by the native inhabitants, 

 and called by them " The Gift of the Great Spirit." The plant 

 deserves trial-culture. 



Leyssera g-naphaloides, Linne. 



South-Africa. A perennial herb of aromatic scent and taste. 

 Much used there as a medicinal tea. 



Ziiatris odoratissima, Willdenow. 



Southern States of North-America. A perennial herb, occurring 

 iu swampy places. The leaves are sometimes used, for the sake of 

 their aromatic odor, to flavor tobacco and other substances [Saun- 

 ders]. L. spicata (Willdenow) is the "Button-Snakeroot," medici- 

 nal in the Eastern States. 



Iiibocedrus Chilensis, Endlicher. 



In cold valleys 011 the Southern Andes of Chili, at from 2,000 to 

 5,000 feet. A fine tree, sometimes 80 feet high, furnishing a hard, 

 resinous wood of a yellowish colour. Libocedrus as a genus is 

 hardly to be distinguished from Thuya, as pointed out more partic- 

 ularly by Bentham. 



Iiibocedrus decurrens, Torrey. 



White Cedar of California, growing on high mountains, in fine 

 groves, up to 9,000 feet, in what Hinchcliff calls the noblest zone of 

 Coniferae of the globe. Attains a height of fully 200 feet, with a 

 stem to 25 feet in circumference. The wood is light, pale-coloured 

 and soft, yet strong, used for exquisite cabinet-work, but also 

 suitable for superior fence-rails and building purposes. According 

 to Dr. Gibbons, the tree is well adapted for wind-breaks, and 

 can be trained into tall hedges.
