A tree' attaining in South America, though rarely, a height of 160 feet. 

 Branchlets tetragonal. Leaves equal in size and uniform in shape in the four ranks ; 

 those on the ultimate branchlets about yV inch long, adnate only at the base, the 

 remaining part free and spreading ; ovate, acute, or rounded at the apex, keeled on 

 the back, concave and glaucescent above ; those on primary axes larger, adnate for 

 the most of their length, the apices only being free and spreading. 



Cones on long branchlets, less than \ inch long, brown. Scales four, minutely

' This tree has been confused by travellers with Fitzroya palagonica, which has very similar foliage when old. In the 

 former, the leaves gradually taper to a rounded or acute apex ; in the latter they are broadest in their upper third, close to the 

 rounded apex. The cones are entirely different.
