IL SYSTEMATIC. 



This is a stunted tree or shrub attaining a height of 20 to 30 feet with a 

 thick, compact bark. Branchlets, when compared with other species, are short, 

 \'ery numerous, erect, compact, terete, and drying a bright green colour ; the 

 internodes are very short, averaging a line long on the penultimate branchlets. 

 Free ends of leaves acute, incurv^ed, the decurrent portion quite rounded on the 

 back, the dorsal ridge being only slightly marked. Male amenta terminal, two 

 to five, but mostly in threes, scarcely exceeding a line in length when matui^e, 

 ovoid to cylindrical in shape. Antheral bracts ovate-orbicular, ciliate, anthers 

 two to three, about half the length of the bract. Female amentum solitary, 

 about one line in diameter. 



Fruit cones solitary, on short thick branchlets, sometimes occurring in 

 clusters, nearly globular, about six lines in diameter before dehiscing, and about 

 I inch in diameter when fully opened; valves valvate, the alternate larger ones 

 about twice the width of the shorter, covered, when mature, with large 

 numerous warts; the dorsal iK)inl almost entirely absorbed in the indurated 

 sporophyll. The central columella three-sided, ])ointed, about Iwo linos long. 

 Seeds two-winged.

 (b) Anatomy. 



In general contour, a cross section through the three decurrent leaves may 

 be said to resemble that of C. glauca, but internally the skeletal structure is 

 specifically different, for in this species it is only occasionally that a leaf trace or
