A tree with the general appearance of A. Douglass. Branches and branchlets

 direction, resupinate from being twisted at the base, linear, mucronulate, in- 

 curved ; silvery beneath, articulated with an elevated tubercle, very short, 

 not more than 2 in. long, rigid, rather sharp-pointed, and very soon falling off 

 the dried specimens. Cones pendulous, cylindrical, 3 in. long. Only a very 

 few plants of A. Menzieszz were raised in the Horticultural Society's Garden 

 in the year 1832 ; so that the species is at present extremely rare in this 

 country. Readily propagated by cuttings. '
