A shrub or tree attaining a height of 50 feet or more, with a hard, compact, 

 furrowed bark. Branchlets with the decurrent leaves, rigid, coarse, the latter 

 dr}dng a fresh green in the herbarium specimens, and are more robust than in any 

 other species of Callitris except C. Roei. Free ends of leaves appressed, margins 

 scarious, obtuse, the decurrent portion of the leaf forming an acute angle, the 

 three producing an equilateral triangular prism — the angles being more acute 

 than in C. calcarata, and the internodes sometimes measuring 6 lines in length. 

 ]\Iale amenta terminal, mostlv solitarv. Female amenta not seen. 



Fruit cones somewhat globose, but in the middle stage when half-grown 

 and on to maturity they are quite top-shaped and glaucous, mostlv solitarv, yet 

 numerous at the base of the older branchlets, drving a light-brown colour, 

 scabrous when young, smooth or slightly rugose in advanced age, under 8 lines 

 in diameter ; the valves are stout, alternateh- rather shorter and more acute, 

 valvate, the dorsal point not very distinct.
