It is an evergreen tree, varying in height according to 
environment. In the far interior it is stunted in growth, 
whilst towards the main Dividing Ranges it attains a height 
of over 100 feet with a diameter from 2 to 3feet. The bark 
is hard, compact, furrowed, but lighter in colour than that 
of C. calearata, R. Br., which forms with it the principal 
Pines of the interior. 
Leaves at first triangular, then decurrent in whorls of 
three, glaucous; branchlets at first terete, the internodes 
being shorter than obtain in most species; the “‘teeth or 
leaf scales’’ short, acute, the decurrent portion only slightly 
rounded. 
Male amenta small, two to four lines long, cylindrical 
oblong or ovoid, very humerous, occurring in general in 
threes at the end of the (leaf series); the stamens in whorls 
of threes, the scale like apex concave, cordate; anther 
cells two to four. Female amenta solitary or not often 
found in clusters, situated generally at the lower part of 
the branchlets. 
Fruiting cones globular, rarely pointed at the top, about 
half inch, exceptionally three-quarter inch in diameter, 
slightly scabrous, valves six alternately large and small, 
the latter about a quarter less in size than the larger ones, 
valvate, channelled at the base; dorsal point scarcely per- 
ceptible. Seeds two or three winged; the central colu- 
mella under two lines. 
Habitat.—It is perhaps quite safe to say that this species 
is facile princeps over its congeners in extent of geo-
