much exposed, and entirely without artificial protec- 

 tion. 



The J. tetragona is very abundant on the mountains of 

 Mexico, especially at high elevations, and forms a large 

 spreading bush not exceeding 4 or 5 feet in height. It is 

 exceedingly beautiful and well worthy of trial. The 

 branches are numerous and spreading, with the ends in- 

 curved, densely covered with leaves and very numerous, 

 stiff, spreading branchlets. This species must not be con- 

 founded with J. Phoenicia, of Linnaeus, which latter plant 

 is known by some writers on the Couiferse as J. tetragona, 

 of Msencb.
