Branchlets tetragonal. Leaves equal in size and uniform in shape in the four ranks ; 
those on the ultimate branchlets about 7, 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 4 inch long, brown. Scales four, minutely

3 This tree has been confused by travellers with /2tzroya patagonica, 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.
